7 Benefits of Body Hair That You Didn't Know

Thing are not as useless as they appear. There are certain things that we do not know the details of, but it does not mean that those have no purpose in them. It is only our lack of knowledge that the science has not discovered any good use for them so far. We notice that scientists are still working on things that are already known and are making new discoveries every day discoveries. With the advancement in technology, new aspects of already discovered things are being explored.

Hair on human body is one such thing. Besides head, eyebrows and eyelashes, hair on the rest of the body are considered unnecessary and are always unwanted. Every effort is made to get rid of them. Here are some interesting details about human hair on different parts of the body.

1. Body hair work like receptors. Scientists have experimented that people with more body hair are better bedbug detectors. Twenty-nine students were part of this experiment. Arms for half of them were shaved to verify how long it would take to detect bedbugs placed on their arm. The researchers found that body hair enhanced the ability to detect bugs on the body quickly. Thus, the hairs served as motion detectors.
2. Hair on the head serve multiple purposes. People have different types of head hair, some have short curly hair, while others have long hair styles. Their colors also vary ranging from black hair to brown. In addition to making your personality attractive by different hairstyles as well keeping the barbers employed who are involved in different hair makeover, they protect our skull from extreme cold or heat. They also help the skull to respire.
3. Hair on the eye brows are not only a thing of beauty. They are specially designed in a way that all of them lay down in the same direction i.e. starting from the mid of the face downwards. The special arrangement is helpful and is actually a protection for eyes against the perspiration or any other liquid coming down from the head. The liquid does not come down straight to the eye, rather changes its direction due to the hair on the eyebrows and passes from the sides.
4. Hair on the eyelashes protect the eyes against dust particles and other microscopic organisms from entering the eye. They are actually our first line of defense against bugs, dust and other irritating objects.
5. Hair in the armpits and in the groin area are often considered a problem and of no use. In addition to being a sign of maturity, the dry hair act as lubricant for shoulder and hip joint during the movement of legs and arms. I am all praise to nature for this wonderful design of human body. In the absence of these hair, friction at these areas would increase that would damage the skin being rubbed continuously during extended walk or manual work.
6. Hair are great defense against malaria as well. The type of mosquito that spreads malaria is Anopheles. That species hates body hair as they warn the person to start sweating and the mosquito does not succeed in its mission of spreading malaria. Although their bite is painless but the motion detectors present on the skin warn the body ahead of time and thus save us from the disease. This is the main reason kids are at higher risk for malaria as they do not have body hair at the early age.
7. It insulates the body against very high or low temperatures. In cold weather, the hot air is trapped in the body hair and thus help the body to lose less heat.
