Leg hair and arm hair developed to help prevent chafing so we could move around without causing friction.
"Letting your body hair grow is what nature intended," says Dr. Nazarian. She adds that you'll be skipping the risk of irritation from razor blades and razor burn, which are two annoying consequences of regular shaving.
To be absolutely clear: There is no hygienic or medical reason you need to remove hair. In fact, the opposite is true. When hair is removed, no matter how it's done, the process may create microscopic traumas and expose you to infection.
If baldness runs in your family, hair loss can occur on your legs as well as your head. Losing hair on your legs is also connected with a number of health issues, like poor circulation, diabetes, thyroid conditions, fungal infections, folliculitis, hormone changes, and pituitary gland disorders.
Like so many things, it comes down to a mixture of genetics and hormones. We know that at least some of the genes for hairiness are carried on the X chromosome – and the way these genes are expressed varies between different men and ethnic groups – but hairiness also correlates with high testosterone levels.
Is body hair a sign of high testosterone? Testosterone can cause hair growth but it's not always a sign of high testosterone levels. Testosterone and oestrogen are sex hormones, and they help determine how your hair grows. This means not only where, but also the texture, thickness and colour of that hair.

H. Harris, publishing in the British Journal of Dermatology in 1947, wrote American Indians have the least body hair, Chinese and black people have little body hair, white people have more body hair than black people and Ainu have the most body hair.
China. China isn't fully westernized, so Chinese notions of beauty differ greatly than American ones (which is refreshing). In China, underarm or leg hair is nothing to be worried about; body hair is considered completely natural and acceptable in their culture. As a result, hair removal just isn't very popular there.
Not shaving reduces skin-on-skin contact friction, which means when you do activities that involve arm movement, like running or walking, your skin is much less likely to get irritated by the friction. This might lead to fewer skin issues like rashes and ingrown hairs.
Leg, chest and back hair
About two-thirds of Britons (64%) - 66% of men and 62% of women - think it's unattractive for women to have hairy legs. Conversely, just 5% say it's unattractive for a man to have hairy legs. A quarter (26%) find men's hairy legs attractive (21% of men and 30% of women said this).
It is totally normal to have pubic hair extend to the upper part of your thighs. Even after your period begins, your body keeps developing: your breasts get fuller and your pubic hair continues to spread for a couple of years. You might have a trail at the groin area of your upper thigh.
If you would prefer to remove your armpit hair, there are plenty of different options available. However, removing the hair only removes the 'house' for the bacteria. The bacteria themselves remain, so if you have no armpit hair but don't wash your armpits, you're still going to have odor.
Pubic hair plays a role in reducing friction during activities such as sexual intercourse. It also plays a role in preventing dirt and pathogens from entering the genitals. A person can safely remove their pubic hair if they wish to, but they do not need to.
Firstly, the sac from which the hair grows (the 'follicle') is oval in shape, compared to straight hair's more circular follicle. Next, curly hair exits the skin's surface at more of an angle than straight hair, causing it to curve as it grows.
Why Do Men Have Chest Hair? The reason men grow chest hair comes down to genetics and biology. It is theorized that chest hair was a positive physical attribute thousands of years ago that helped keep your body warm. Chest hair also made it easier to visually spot fleas on the body.
As people age, they may lose hair on their legs for a variety of reasons. Hair loss can occur on your legs just as it can on your head, and, similarly, genetics can play a role in this issue. If baldness runs in the family, you could also experience hair loss on other parts of your body, such as your legs.
If you feel like you have a lot of body hair, it might be serious. Body hair is normal, and it exists for an evolutionary reason: To keep us warm. But too much of a good thing can be a sign that something else is going on in your body.
The short answer is there isn't a proven link between orgasms and testosterone levels, so we don't know how it affects you in the short term. However, you can take comfort in knowing that masturbating will not negatively affect your testosterone levels—or other aspects of your life—long-term.
The individual occurrence and characteristics of chest hair depend on the genetic disposition, the hormonal status and the age of the person. The genes primarily determine the amount, patterns and thickness of chest hair. Some men are very hairy, while others have no chest hair at all.
Aromatic chemicals (namely testosterone) are released through these glands, which is what you might call the whole “manly musk.” In turn, chest hair traps those odors and even strengthens them, which is basically a way of saying “I am a man” very loud, via odor.
