Why Do Humans Need Armpit Hair?

#1 We Were Once Covered Completely By Hair

Everybody knows that ancient 'people' were completely covered in hair. But as time went by, and Man began to evolve, and the hair disappeared little by little. Nevertheless, even today, some people still have hair in certain places on their bodies, some much more than others.

#2 Some Hair Is Needed

Some of the hair left on our bodies through evolution is required for certain things. For instance, eyelashes keep dust and debris from getting into our eyes. The eyebrows keep sweat from dripping into your eyes and causing irritation.

#3 That Pesky Nose And Ear Hair

Hair in your nose and your ears prevent tiny objects from getting into your body. The hair in the nose helps you when smelling certain things as the scents stick to the follicles. In the ears, the hair follicles act as tiny antennas, picking up noise or blocking it by vibrations.

#4 Some People Have Hair In Unusual Places

A lot of people grow hair in places they wish they it never would, and usually, they don't know the reason why. Like chest hair. Some like it and some not so much, especially females. But it does grow on women's chests when their hormones are out of balance. Body hair serves as a defensive barrier against injuries. A thick layer of body hair acts as a pillow and can actually soften any impact. Hair on the toes and feet are likely caused by the same thing but are often overlooked as normal, especially if the hair is light and thin.

#5 The Hair On Your Head Keeps You From Getting A Brain Freeze Or Overheating

That hair growing on your head actually prevents you from getting too hot or too cold. In the Summer your head doesn't overheat and in the Winter your head stays just the right temperature because of your hair. Your body regulates its temperature based on the hair on your skin and acts accordingly.

#6 The Hair On Your Body Act As An Extra Layer Of Warm Skin

Your pesky body hair, that everybody is trying to get rid of all of a sudden, does basically the same thing as the hair on your head. Air running through your hair keeps you warm and can act as a layer of clothing. If you've noticed that when you get cold your hair stands on end and you get goosebumps, that is because each one of your hairs is connected to a muscle causing the 'chicken' bumps to occur, alerting your body that the temperature is changing.

#7 Armpit And Pubic Hair Do Not Grow By Accident

It is in those place on the body where the lymph nodes are located and overheating is not good for them. Armpit and pubic hair reduced friction when you walk or move your arms. Armpit hair and pubic hair also increase your attractiveness because they trap the secretions segregated by sebaceous glands. When bacteria destroys those fluids, a musky odor, which can be very sexually stimulating, appears and is trapped in the hairs.

#8 The Sweaty, Musky Odor Emitted By Armpits And Pubes Attract The Opposite Sex

When bacteria destroys those fluids, a musky odor, which can be very sexually stimulating, appears and is trapped in the hairs. A lot of people are now trimming their pubic hair and this can be dangerous, also causing bacteria to build up around the genitals when it once would have been trapped by the hairs protecting them. That doesn't mean it's okay to stop washing or keeping your armpits and pubes fresh and clean in order to get the attention of the opposite sex. It does not work because that musky smell soon turns into a foul odor after 16-24 hours, and that's not very attractive.

#9 Armpit Hair Is Sexy To Some

The armpit hair is another issue, and many women worldwide have agreed that it is not healthy to keep it totally shaved off, though it is considered more attractive to the male eye. Men have never worried about their armpit hair, and in many cultures, it is considered sexy, even when they sweat. Of course, again we stress that you need to keep up your hygiene.

#10 You Have To Keep That Hair And Where It Grows Clean

Different cultures have different standards on the removal of body hair, but most everyone agrees that you should always keep your armpits and pubic areas clean. Not following the normal hygiene rules can have the opposite effect from alluring someone to you sexually, causing you to completely turn off the opposite sex and everyone else as well.

#11 Interesting Facts To Ponder About Your Hair

Humans have over 130,000 hairs growing on their heads. More than 90% of them are growing right now at a speed of one centimeter per month. The other 10%, sadly, is dying.

#12 Hair Also Has A Lifespan

The lifespan of a single hair is 2-4 years for men and 3 to 5 years for women. Every day, we lose over 100 individual hairs. So don't worry if you see a hair in your salad, it's pretty normal. Everyone is losing hair, though it's disgusting. Your armpit hair takes three more years on average to die off for both sexes.

#13 Your Hair Knows More About You Than You Do

Your hair also has a memory and can tell a story of your life. Three centimeters of your hair are enough for scientists to figure out what you've been eating the last month, where you live, if you've taken medications, and even if you've been feeling sad or happy. That's the reason detectives on TV look so happy when they find strands of hair at a crime scene.
