Why Is Hair Important To Us?
For literal millennia, human societies have ascribed meaning to hair. Today, a good head of hair is associated with feminine beauty and male virility. On a deeper level, our hair also communicates our social status, our sexuality, and even a level of personal responsibility via our control over our hair.
1.Hair regulates body temperature. Being indoors in a cold room or outdoors in cold weather makes our muscles contract, causing them to pull the hair into an upright position. These erect strands trap air and serve as insulation to protect the body from the cold. This explains why a person who has more hair feels warmer than someone who has little or none at all. Hot temperatures have an opposite effect. As our sweat glands secrete sweat that evaporates to cool us down, the muscles relax, making the hair lie flat to release heat
2. Hair extends our sense of touch. It’s amazing how even before an object touches our skin, our hair makes it possible for us to feel something.
3. Hair protects our bodies from harmful objects. Hair covers almost all of our body except for the palms of our hands, soles of the feet, and lips. Aside from providing cover from the heat of the sun, body hair such as eyebrows, eyelashes, and those found in nostrils help keep dust and foreign matter out.
4. Hair identifies you. Your hair may be a dead giveaway for forensic analysis and paternity testing, but for many, hair is simply the ultimate form of expression.
