WHAT HAPPENS DURING $EX

While most of us are sure that we like to have $ex, most of us also haven't spent much time thinking about what happens physiologically while we are engaged in the act. The $exual-response cycle is divided into four phases: excitement, plateau, orgasm and resolution. There is no distinct beginning or end to each phase -- they're actually all part of a continuous process of $exual response.

Keep in mind that this is a very general outline of what happens to each of us as we become $exually aroused. There is much variation among individuals, as well as between different $exual events.

Simultaneous Orgasms

Both men and women go through all four phases, except the timing is different. Men typically reach orgasm first during intercourse, while women may take up to 15 minutes to get to the same place. This makes the likelihood of simultaneous orgasm during intercourse a rare event.

Phase One: Excitement

This phase usually begins within 10 to 30 seconds after erotic stimulation, and can last anywhere from a few minutes to many hours.

Men: The penis becomes slightly erect. A man's nipples may also become erect.

Women: Vaginal lubrication begins. The vagina expands and lengthens. The outer lips, inner lips, clitoris and sometimes breasts begin to swell.

Both: Heart rate, blood pressure and breathing are all accelerated.

Phase Two: Plateau

The changes that started in the excitement phase continue to progress.

Men: The testes are drawn up into the scrotum. The penis becomes fully erect.

Women: The vaginal lips become puffier. The tissues of the walls of the outer third of the vagina swell with blood, and the opening to the vagina narrows. The clitoris disappears into its hood. The inner labia (lips) change color (although it's a bit hard to notice). For women who've never had children, the lips turn from pink to bright red. In women who've had children, the color turns from bright red to deep purple.

Both: Breathing and pulse rates quicken. A "$ex flush" may appear on the stomach, chest, shoulders, neck or face. Muscles tense in the thighs, hips, hands and buttocks, and spasms may begin.

Phase Three: Orgasm

This is the climax of the cycle. It is also the shortest of the four phases, usually only lasting a few seconds.

Men: First, seminal fluid collects in the urethral bulb. This is when a man may have the sensation that orgasm is certain, or "ejaculatory inevitability." Next, semen is ejaculated from the penis. Contractionsoccur in the penis during the orgasmic phase.

Women: The first third of the vaginal walls contract rhythmically every eight-tenths of a second. (The number and intensity of the contractions vary depending on the individual orgasm.) The muscles of the uterus also contract barely noticeably.

Both: Breathing, pulse rate and blood pressure continue to rise. Muscle tension and blood-vessel engorgement reach a peak. Sometimes orgasm comes with a grasping-type muscular reflex of the hands and feet.

Phase Four: Resolution

This phase is a return to the normal resting state. It can last from a few minutes to a half-hour or longer. This stage is generally longer for women than men.

Men: The penis returns to its normal flaccid state. There is usually a refractory period, where it's impossible to orgasm again until a certain amount of time has passed. The amount of time varies among men by age, physical fitness and other factors.

Women: The uterus and clitoris return to their normal positions. Some women may be able to respond to additional stimulation with additional orgasms.

Both: Swelling recedes, any $ex flush disappears, and there is a general relaxation of muscle tension.

Understanding what's happening to you and your partner's bodies during $ex can only aid in the full enjoyment of the experience. Combine this with some good communication skills, and you've found the key to unlock $exual pleasure and your heart's desires.

WHY DO MOSQUITOES BITE SOME PEOPLE MORE THAN OTHER ?

Blood type, metabolism, exercise, shirt colour and even drinking beer can make person so delicious to mosquitoes

You’re not alone. An estimated 20 percent of people, it turns out, are more delicious for mosquitoes, and get bit more often than normal.  while scientists don’t yet have a cure for the ailment, other than preventing bites with insect repellent.  They do have a number of ideas regarding why some of us are more prone to bites than others. Here are some of the factors that could play a role:

Blood Type

As mosquitoes bite us to harvest proteins from our blood—research shows that they find certain blood types are more tasty than others. One study found that in a controlled setting, mosquitoes landed on people with Type O blood nearly twice as often as those with Type A. People with Type B blood fell somewhere in the middle of this itchy spectrum. Additionally, based on other genes, about 85 percent of people secrete a chemical signal through their skin that indicates which blood type they have, while 15 percent do not, and mosquitoes are also more attracted to secretors than

Carbon Dioxide

Mosquitoes locate their targets is by smelling the carbon dioxide emitted in their breath—they use an organ called a maxillary palp. With the help of it can detect carbon dioxide from as far as 164 feet away. As a result, people who simply exhale more of the gas over time—generally, larger people—have been shown to attract more mosquitoes than others. This is one of the reasons why children get bit less often than adults, on the whole.

Exercise and Metabolism

In addition to carbon dioxide, mosquitoes find victims at closer range by smelling the lactic acid, uric acid, ammonia and other substances expelled via their sweat, and are also attracted to people with higher body temperatures. Because strenuous exercise increases the buildup of lactic acid and heat in your body, it likely makes you stand out to the insects. Meanwhile, genetic factors influence the amount of uric acid and other substances naturally emitted by each person, making some people more easily found by mosquitos than others.

Beer
Just a single 12-ounce bottle of beer can make you more attractive to the insects, one study found. But even though researchers had suspected this was because drinking increases the amount of ethanol excreted in sweat, or because it increases body temperature, neither of these factors were found to correlate with mosquito landings, making their affinity for drinkers something of a mystery.

Pregnancy

In different studies, pregnant women have been found to attract roughly twice as many mosquito bites as others, likely a result of the fact the unfortunate confluence of two factors: They exhale about 21% carbon dioxide and are on average about 1.26 degrees Fahrenheit warmer than others.

Clothing Colour

This one might seem absurd, but mosquitoes use vision (along with scent) to locate humans, so wearing colours that stand out (black, dark blue or red) may make you easier to find, at least according to James Day, a medical entomologist

Genetics

As a whole, underlying genetic factors are estimated to account for 85% of the variability between people in their attractiveness to mosquitoes—regardless of whether it’s expressed through blood type, metabolism, or other factors. Unfortunately, we don’t (yet) have a way of modifying these genes.

WHAT HAPPENS WHEN YOU SLEEP ?

When we sleep well, we wake up feeling refreshed and alert for our daily activities. Sleeping affects how we look, feel and perform on a daily basis, and one can have a major impact on our overall quality of life. We spend about 1/3 of our lives sleeping. But far from being wasted time, from the moment we slide into unconsciousness, a whole raft of functions takes place to make sure that we get optimal benefit from our nightly rest. To get the most out of our sleep, both quantity and quality are most important. Teens need at least 8 hours and on average 9¼ hours a night of uninterrupted sleep to leave their bodies and minds rejuvenated for the next day. Sleeping is the time the body can undergo repair and detoxification. Poor sleep patterns are linked to poor health - and those who sleep less than six hours a night have a shorter life expectancy than those who sleep for longer.  If sleep is cut short, the body doesn’t have time to complete all of the phases needed for muscle repair, memory consolidation and release of hormones regulating growth and appetite. Then we wake up less prepared to concentrate, make decisions, or engage fully in school and social activities.

Sleep is the time the body can undergo repair and detoxification. Poor sleep patterns are linked to poor health - and those who sleep less than six hours a night have a shorter life expectancy than those who sleep for longer. So sleep has a profound effect on our mental, emotional and physical wellbeing.

How Does Sleep Contribute to All of These Things?

Sleep architecture follows a pattern of alternating REM (rapid eye movement) and NREM (non-rapid eye movement) sleep throughout a typical night in a cycle that repeats itself about every 90 minutes.

What role does each state and stage of sleep play?

NREM (75% of night): As we begin to fall asleep, we enter NREM sleep, which is composed of stages 1-4

Stage 1

• Between being awake and falling asleep
• Light sleep

Stage 2

• Onset of sleep
• Becoming disengaged from surroundings
• Breathing and heart rate are regular
• Body temperature drops (so sleeping in a cool room is helpful)

Stages 3 and 4

• Deepest and most restorative sleep
• Blood pressure drops
• Breathing becomes slower
• Muscles are relaxed
• Blood supply to muscles increases
• Tissue growth and repair occurs
• Energy is restored
• Hormones are released, such as: Growth hormone, essential for growth and development, including muscle development
• REM (25% of night): First occurs about 90 minutes after falling asleep and recurs about every 90 minutes, getting longer later in the night
• Provides energy to brain and body
• Supports daytime performance
• Brain is active and dreams occur
• Eyes dart back and forth
• Body becomes immobile and relaxed, as muscles are turned off.

ARE YOU SLEEPING CORRECT ? KNOW WHICH POSITION IS CORRECT.

Sleep is a natural part of the daily biological functions and we spend some time of the 24 hours sleeping. Sleep cycles are different for different persons and while 5 to 6 hours of sleep may be enough for some people, others may need up to 8 hours of sleep to feel refreshed. How you sleep is as important as the duration. This is one area which is often neglected by people.

Why sleeping positions are important? Sleeping positions are very important as you stay in a single position for hours at a time every day, and if these habits are bad, they can contribute to spinal problems. Thus, many of the spinal problems can also be alleviated by sleeping correctly.

Some of the bad sleeping positions that may adversely affect your spine are as follows.

• On your stomach - This position is in overall a bad position as it curls up the spine, especially where the neck meets the spine and can cause spinal deformities over a long period of time. Certain adjustments to this position can lessen the effects, but it is important to try to change habits and sleep in a better position.
• The fetal position - Although this is one of the more natural positions and most babies are crouched up in this form in the mother's womb; as a sleeping position, it has its disadvantages as well. The lower spine is especially put under a lot of stress when someone curls up in this position.
• On your side - Although this is safer compared to the other two, sleeping on your sides straight would cause blood circulation issues and also put a lot of stress on the relevant organs, depending on the side you were sleeping on.

In all of the cases, slight adjustments to these positions will lessen the stress on the spine and also help you sleep better.

Some of the adjustments that you can make are:

1. Sleep with a pillow between your knees to align your hips and cause less strain on the spine.

2. If you don't have sleep apnea, put a pillow under your knees to raise them while lying on you back.

3. If you sleep on your back, try to consciously change your position to sleep on the side.

4. Try and actively change your posture throughout the day to ensure good sleeping position at night.

How to Keep Your Lungs Healthy

The lungs are an essential respiratory organ. Their main function is to transport oxygen from the atmosphere into the bloodstream and to release carbon dioxide from the bloodstream into the atmosphere. The lungs never rest. In just one day, a healthy person breathes nearly 25,000 times. The body has a natural defence system designed to protect the lungs. This works very well most of the time, keeping out dirt and fighting off germs. However, several harmful substances can damage the airways and threaten the lungs’ ability to work properly, which can lead to lung disease.

Some common lung diseases are asthma, chronic obstructive pulmonary disease (COPD), bronchitis, pneumonia, emphysema, cystic fibrosis, tuberculosis, lung cancer and acute respiratory distress syndrome (ARDS). People with lung disease have difficulty breathing and some diseases can even lead to respiratory failure. There are many things that you can do to keep your lungs functioning properly. Simple lifestyle changes, dietary changes and healthy habits can be highly beneficial for your lungs.

how to make lungs healthy

Here are some of the ways to keep your lungs strong and healthy.

1. Quit Smoking

If you smoke, it is time to quit to improve the condition of your lungs. Cigarette smoke contains thousands of harmful chemicals, some of which can cause health problems. In fact, smoking is the major cause of serious lung diseases like lung cancer and COPD. Cigarette smoke can narrow the air passages and make breathing more difficult. It causes chronic inflammation or swelling in the lungs. With time, cigarette smoke can destroy lung tissues, which in turn increases your risk of lung cancer. If you suffer from any kind of lung disease, giving up smoking can help manage your condition and improve your quality of life. Be determined to quit smoking and get help from professionals if needed.

 2. Avoid Second hand Smoke

Non-smokers must avoid exposure to second hand smoke to improve the condition of their lungs. Second hand smoke is highly toxic and can cause havoc to your lungs and your overall health. 

Here are some things you can do to avoid second hand smoke:

Do not allow other people to smoke in your home, car or workplace.

Support businesses and activities that are smoke-free.

Avoid public places that permit smoking.

Stay at smoke-free hotels when travelling to avoid residual smoke from previous patrons.

3. Limit Your Exposure to Pollutants

In addition to cigarette smoke, there are various other pollutants present in the air that are harmful for your lungs as well as overall health. Even the synthetic fragrances used in various laundry products and air fresheners emit toxic chemicals. Avoid highly polluted and industrialized areas. Do your bit to minimize outdoor pollution and help create a cleaner environment. For example, whenever possible, walk or ride your bicycle instead of driving.

When building or remodelling your house, opt for eco-friendly options like formaldehyde-free cabinetry, linoleum instead of vinyl flooring, low or no VOC paints, etc.

4. Improve Indoor Air

In a late 1980s NASA study, it was found that several houseplants act as natural air purifiers as they filter out common volatile organic compounds (VOCs) including formaldehyde, benzene and trichloroethylene. Use at least 2 houseplants per 100 square feet of space. These plants should be in 10- to 12-inch pots. Get indoor plants such as a fern, spider plant, peace lily, bamboo palm, aloevera, English Ivy, dracaena, and others. Make sure to keep the foliage dust-free. Also, do not overwater the plants as it may lead to mold growth.

Minimize the use of harsh cleaners and cleaners with strong fragrances. Avoid using aerosol sprays. Ensure adequate ventilation.

5. Do Deep Breathing Exercises Daily

Breathing feeds oxygen to every cell in the body. Without sufficient oxygen, people are more prone to lung problems and even heart disease. With regular deep breathing exercises, you can easily strengthen your lungs. It can also help clear out toxins that may have built up in the lungs. This in turn helps improve lung performance and clear airways. Sit down in a relaxing and quiet place. Close your eyes, and breathe in deeply through your nose. Count to five, slowly inhaling the entire time. Hold your breath for a few seconds, then exhale slowly. Repeat this breathing exercise 6 to 8 times.

Perform this deep breathing exercise on a daily basis to help cleanse your lungs and keep you stress free. If you are not able to master the art of deep breathing, join a breathing club where people with lung and breathing problems can learn about this technique.

6. Play a Wind Instrument

You can play a wind instrument like a flute, oboe, tuba, saxophone, mouth organ or clarinet to improve your lung health. You need to use your lungs’ capacity to the fullest to play any of these instruments. This gives your lungs a regular workout and helps improve their air capacity.

Learn how to play a wind instrument to increase your lung capacity. Also, singing works the diaphragm and keeps your lungs healthy. If music and singing are not for you, try to blow a balloon using deep breaths to increase lung capacity. Blow a few balloons daily to improve your lungs’ ability to pump more air, stronger and longer.

HOW EYE DISCHARGE WHEN YOU SLEEP ?

Eye discharge, or "sleep" in your eyes, is a combination of mucus, oil, skin cells and other debris that accumulates in the corner of your eye while you sleep. It can be wet and sticky or dry and crusty, depending on how much of the liquid in the discharge has evaporated. Other slang terms used to describe eye discharge include eye boogers, eye mattering, eye gunk and eye pus. Sometimes called rheum, eye discharge has a protective function, removing waste products and potentially harmful debris from the tear film and the front surface of your eyes.Eye discharge

Abnormal eye discharge could indicate an eye infection or disease.

Your eyes produce mucus throughout the day, but a continuous thin film of tears bathes your eyes when you blink, flushing out the rheum before it hardens in your eyes.

When you're asleep -and not blinking — eye discharge collects and crusts in the corners of your eyes and sometimes along the lash line, hence the term "sleep in your eyes."

Some sleep in your eyes upon waking is normal, but excessive eye discharge, especially if it's green or yellow in color and accompanied by blurry vision, light sensitivity or eye pain, can indicate a serious eye infection or eye disease and should be promptly examined by your eye doctor.

Where Does Eye Mucus Come From?

Eye discharge is a function of your tear film and a necessary component of good eye health. Eye rheum primarily consists of thin, watery mucus produced by the conjunctiva (called mucin), and meibum — an oily substance secreted by the meibomian glands which helps keep your eyes lubricated between blinks. When not washed away by tears, the accumulated debris, or "mattering," collects in the inner corner of the eye as well as along the lash line.

Causes of Eye Discharge

Sleep in your eyes usually isn't cause for alarm, but if you notice a difference in consistency, color and quantity of eye gunk, it could indicate an eye infection or disease.

Common eye conditions associated with abnormal eye discharge include:

Conjunctivitis: Eye discharge is a common symptom of conjunctivitis (pink eye), an inflammation of the conjunctiva — the thin membrane that lines the "white" of the eye (sclera) and the inner surface of the eyelids.

In addition to itchy, gritty, irritated and red eyes, conjunctivitis typically is accompanied by white, yellow or green eye mucus which can form a crust along the lash line while you sleep. In some cases, eyelid crusting can be so severe that it temporarily seals your eye shut.

UNKNOWN FACTS OF BASIL PLANT

• When suffuring form cold, fever and cough, if your eat 4 basil leaves you will have instant relief . If not take a glass of water and add some basil leaves and warm the water for some time after some and by drinking the warm water will help you to fight against the infections in your body.  When you are facing unbearable cough take a glass of water and add  cloves and basil leaves and warm it. By having them will help you from unbearable cough.
• People having less immunity power are advised to take basil leaves. Antibodies  present in basil leaves increases your immunity power.  When your are feeling stress, if you eat basil leaves they will release hormones that helps to reduce stress. If your are more prone to stress it is advised to take 10-12 basil leaves.
  
• By eating basil leaves blood also get purified. It contains vitamin "A", it will improve your vision and anti-oxidants present in them are helpful for heart.
• So many people are facing indigestion problem, then add some honey in basil juice and having it will help you from that. When you are facing head ache have some basil leaves in steaming machine and having it to head will rejuvenate nerves in head region and reduces head-ache. In diabetes people when sugar levels increases in blood, add basil leaves in decoction and having it will reduces sugar levels.
• One of the basil plant’s uses is that its leaves have a strengthening effect on the kidneys. In case of renal stones, the consumption of juice of basil leaves mixed with honey helps remove these stones through the urinary tract. Basil being a detoxifying agent can help to reduce uric acid level which is the main reason behind kidney stones.
• Basil juice is an effective remedy for sore eyes and night blindness, which is generally caused by lack of Vitamin A. Two drops of basil juice can work wonders for the eyes. It soothes eyes and reduces stress. Also, it can protect from conjunctivitis, boils and other problems of the eyes which are caused mainly due to bacterial and fungal infections by washing eyes with water soaked in basil leaves.
• Basil leaves act as relaxants for your eyes to sooth stress induced fine lines. Chewing a couple of basil leaves helps to ward off eye problems caused by free radicals such as vision degeneration, cataracts and glaucoma. Basil leaves juice is an effective remedy for sore eyes and night blindness.
• Chain smokers can try chewing basil leaves to get rid of their addiction. These can be more beneficial than nicotine patches, flavored gum or even plain candy to curb the urge. While the juice has a cooling effect on your throat, the chewing will distract you and the antioxidants will repair the damage caused due to years of smoking.
• This herb also prevents insect stings and bites. A teaspoon of fresh juice should be applied on the affected areas and repeated after a few hours. A paste of fresh roots is also effective in case of bites of insects and leeches. Apply a paste of basil leaves and roots ground together on the sting of the scorpion. It will completely eliminate the effects of poison. Also in such cases, crushing a few leaves of basil and mixing it with lemon helps too. Apply it on the area of the sting and it will cure the problem. The pain caused by the sting can be reduced by drinking basil juice and also by applying it on the sting.

HOW HEIGHT EFFECTS ON HEART

When compared with height people short people will face more heart problems. The reason behind this is gene problem. In human body 180 genes will be responsible in determining height. In those genes which will responsible for shortness will have LDL cholesterol, triglycerides in higher quantities which will be responsible for blocking of blood vessels. Britain researchers found that for decrease of  every 2.5 inches will have 14% of chances of getting heart attacks. When compared with females it is more in males. But being short is not your fault so don't get disappointed. As we don't have chance to choose our parents, we can choose our health habits. By this we can win against genes. By Having healthy diet, maintaining good weight, reducing the stress, we can keep our health in safe up to 90%. Smoking and having high cholesterol can be more dangerous than being short. Even height people will have heart problems. So without comparing with height those who follow following tips can have healthy heart. 

1. Quit smoking:

If you smoke, you are more than twice as likely to have a heart attack as nonsmokers, and you’re much more likely to die if you do have a heart attack.

2.Improve cholesterol levels:

You're more likely to get heart disease if you have:

Total cholesterol level over 200

HDL ("good") cholesterol level under 40

LDL ("bad") cholesterol level over 160

Triglycerides over 150

Cholesterol isn't the only thing that matters. To help lower cholesterol levels, eat a diet low in cholesterol, saturated fat, and refined sugars.

3.Control high blood pressure:

More than 50 million people in the U.S. have hypertension, or high blood pressure, making it the most common heart disease risk factor. Exercise and healthy eating help. Some people may need medicine to control their blood pressure, too.

4.Get active:

People who don't exercise are more likely to get heart disease, and die from it, than people who are active. Check with your doctor before starting a new exercise program, especially if you aren't active now. She can tell you what you can do.

5. Follow a heart-healthy diet:

Eat foods that are low in fat and cholesterol. Just about everyone should eat more fruits, vegetables, whole grains, beans, nuts, legumes, and other plant-based foods. The fiber is good for your cholesterol, and you'll get vitamins the natural way, from foods. You can still eat fish (especially salmon or tuna, which are high in good-for-you omega-3 fatty acids), poultry, and meat, but make it lean and keep the portions modest. Also limit salt and sugar. Most people get too much of both.

6. Get to a healthy weight:

Losing extra weight is good for your heart. It can also help you lower high blood pressure and manage diabetes.

7. Control diabetes:

Diabetes makes heart disease more likely. Many people who have diabetes don't know it. Get tested and get treated.

8. Manage stress and anger:

Everyone has stress, and it's normal to get angry now and then. When stress and anger flare up, especially if it happens a lot, that's a problem. Managing your stress and handling your anger in healthy ways puts you back in charge.

HOW WILL PIMPLES PRODUCE

A pimple is a small pustule. Pimples are small skin lesions or inflammations of the skin - they develop when sebaceous glands (oil glands) become clogged and infected, leading to swollen, red lesions filled with pus. Pimples are also known as spots or zits. The development of pimples is primarily connected to oil production, dead skin cells, clogged pores and bacteria (although yeast infection can also cause pimples to develop). Sebaceous glands, which are located at the base of hair follicles, can become overactive due to hormone disregulation, which is why acne is most commonly associated with puberty, and why breakouts occur around the time of menses. The most likely parts of the body to be affected by pimples are the face, back, chest and shoulders due to the proliferation of sebaceous glands in these areas of skin. Pimples are a sign of acne, especially when a breakout occurs. Dermatologists and other experts are increasingly concerned about the long-term use of antibiotics for acne treatment, and its contribution to bacterial resistance. Experts from the Center of Evidence-Based Dermatology at the University of Nottingham, England, wrote in The Lancet that although pharmacies are well stocked with a wide range of acne medications, few studies have been carried out regarding their efficacy.

Sebaceous glands

A diagram of the sebaceous glands (image by Open Stax College)

The sebaceous glands are tiny skin glands which secrete sebum - a waxy/oily substance - to lubricate the skin and hair of mammals, including humans.

Sebaceous glands are found all over human skin with the exceptions of the palms and soles. There is a greater concentration of sebaceous glands on the face and scalp. At the rim of the eyelids, Meibomian or tarsal glands are a special kind of sebaceous gland that secrete meibum, a special type of sebum that helps maintain the eye's tear-film by preventing evaporation.

Several medical conditions are linked to an abnormality in sebaceous gland function, including:

• Acne (pimples).
• Sebaceous cysts - closed sacs or cysts below the surface of the skin.
• Hyperplasia - the sebaceous glands become enlarged, producing yellow, shiny bumps on the face.
• Sebaceous adenoma - a slow-growing tumor (benign, non-cancerous) usually presenting as a pink, flesh-colored, or yellow papule or nodule.
• Sebaceous gland carcinoma - an aggressive (cancerous) and uncommon skin tumor.

If a breakout occurs, doctors recommend that pimples be treated promptly to prevent the risk developing severe acne. There is also the danger that untreated severe acne may result in visible scars on the skin.

Causes of pimples / zits

The sebaceous glands, which produce sebum, exist inside the pores of our skin. The outer layers of our skin are being shed continuously. Sometimes, dead skin cells are left behind and get stuck together by the sticky sebum, causing a blockage in the pore. Pore blockage is more likely to occur during puberty (the process of physical changes by which a child becomes an adult capable of reproduction) as the sebaceous glands produce more sebum at this time. Where sebum and dead skin cells accumulate and block a pore, this encourages the growth of undesirable bacteria, including Propionibacterium acnes - the slow-growing bacterium linked to acne. Propionibacterium acnes generally exists harmlessly on our skin; however, when the conditions are right, it can reproduce more rapidly and become a problem. The bacterium feeds off the sebum and produces a substance that causes an immune response, leading to skin inflammation and spots. Researchers at the Washington University School of Medicine identified two unique strains of P. acnes in the skin of 20% of people with pimples, while those with healthy skin tended not to harbor these strains. The situation was reversed for another strain of P. acnes: those with pimples tended not to harbor this strain, but it was present in healthy skin. As such, it seems that particular types of bacteria determine the severity and frequency of pimples.

Pimples and acne have also been linked to yeast infections, with a group of yeasts called Malassezia thought to be the key culprit. These yeasts grow on the skin of the forehead and chest, but rarely on the sides of the face, and do not inhabit the same pores as P. acnes. As such, treatments that seek to eradicate these yeasts or P. acnes can unwittingly create ideal conditions for the other.

People prone to acne have been found to have skin that is especially sensitive to normal blood levels of testosterone - a natural hormone found in both males and females. In such people, testosterone can trigger the sebaceous glands to produce excess sebum, increasing the likelihood of clogged pores.

Despite being related to bacterial infection, pimples are not contagious. You cannot catch pimples from another person.

Researchers from New York University reported in the Journal of the Academy of Nutrition and Dietetics that dairy products and high glycemic index foods are linked to pimples. The researchers found that people who eat a lot of high glycemic index foods and dairy products are more likely to have acne. They also suggested that using medical nutrition therapy may help in the treatment of acne.

In addition to following a low-Glycemic Index, dairy-free diet, it is also helpful to ensure a good intake of healthy polyunsaturated and monounsaturated fats. Despite pimples being caused by blocked pores due to excess sebum production, fat-free or very low-fat diets are not recommended for acne as too little fat in the diet can actually dry out the skin and prompt the body to ramp up sebum production.

A good intake of fats from nuts, seeds, and olive oil appears to help by keeping inflammation in check; supporting the body in maintaining healthy blood sugar levels; and maintaining good skin moisture levels so as to provide an effective barrier and immune response to prevent bacterial infection.

Having pimples or acne can be hereditary.

Symptoms of pimples

There are several different types of pimples and they have different signs and symptoms:

• Whiteheads - also known as a closed comedo. These are very small and remain under the skin, appearing as a small, flesh-colored papules.
• Blackheads - also known as an open comedo. These are clearly visible on the surface of the skin and are black or dark brown due to the oxidation of melanin, the skin's pigment. Some people mistakenly believe they are caused by dirt, because of their color, and scrub their faces vigorously - this does not help and may irritate the skin and cause other problems.
• Papules - these are small, solid, rounded bumps that rise from the skin. The bumps are often pink.
• Pustules - these are pimples full of pus. They are clearly visible on the surface of the skin. The base is red and the pus is on the top.
• Nodules - these are morphologically similar (similar structure) to papules, but larger. They can be painful and are embedded deep in the skin.
• Cysts - these are clearly visible on the surface of the skin. They are filled with pus and are usually painful. Cysts commonly cause scars.

How common are pimples (acne)?

Acne is the most common skin condition in adolescents. According to a review in the British Medical Journal:

• More than 80% of teenagers get acne at some point.
• A community sample of 14 to 16 year-olds in the United Kingdom revealed that acne affected 50% of them.
• A sample study of adolescents in New Zealand found acne was present in 91% of boys and 79% of girls.
• A sample study of adolescents in Portugal found that the average prevalence of acne (in both sexes) was 82%.
• 30% of teenagers with acne required medical treatment because of its severity.
• General practitioners (GPs, primary care physicians) in the UK reported that 3.1% of 13 to 25 year-old patients visited them complaining of acne.

NO MORE BLOOD CANCER WITH COLOSTRUM

Mother milk is also called as Colostrum in medical terminology. Colostrum (known colloquially as beestings, bisnings or first milk) is a form of milk produced by the mammary glands of mammals (including humans) in late pregnancy. It is very important to infants. It increases immunity power and helps to healthy growth of child. So at-least for 6 months infants should have mother milk (colostrum). This will help infants from infections, allergies, sudden death, etc. Now recent studies proved that colostrum helps to prevent blood cancer (leukemia ). Colostrum contains antibodies to protect the newborn against disease. In general, protein concentration in colostrum is substantially higher than in milk. Fat concentration is substantially higher in colostrum than in milk in some species, e.g. sheep and horses, but lower in colostrum than in milk in some other species, e.g. camels and humans.Colostrum has an especially important role to play in the baby's gastrointestinal tract. A newborn's intestines are very permeable. Colostrum seals the holes by "painting" the gastrointestinal tract with a barrier which mostly prevents foreign substances from penetrating and possibly sensitizing a baby to foods the mother has eaten. Colostrum also contains high concentrations of leukocytes, protective white cells which can destroy disease-causing bacteria and viruses.

The colostrum gradually changes to mature milk during the first two weeks after birth. During this transition, the concentrations of the antibodies in your milk decrease, but your milk volume greatly increases. The disease-fighting properties of human milk do not disappear with the colostrum. In fact, as long as your baby receives your milk, he will receive immunological protection against many different viruses and bacteria. So it is advised to have your child colostrum at-least for six months.
