Most of us know hair are dead cells being rejected from the body building up as keratin and proteins on top of the head. But those beautiful luscious locks of yours aren't as dead and useless as you think. Besides completing our style as human, hair is part of the nervous system. Give yourself a moment to let that sink in. Though hair is dead and has no pain receptors, getting your hair cut can still be a painful experience for some. But that's neither here nor there. Our hair is connected to an entirely different sense, a sixth sense? Of all five major senses, tactile (touch) perception is the least understood. More than two dozen unique types of nerve endings are programmed to transmit vast amounts of information through the skin and to the brain within seconds, and science still doesn't understand how this happens. Hair, being part of this system, acts as a type of antennae to the body. So, not only does hair sense touch, but it could also help sense when environments are 'strange' or dangerous. Has your hair ever risen when you're scared or when you've sensed something uneasy in your surroundings? Hair is also connected to our feelings and emotions, turning grey or even falling out when someone goes through a big shock in their life. There is actual evidence that when Jesus was sentenced to crucifixion, his hair turned grey over night. Native Americans believed that hair helped them with their intuition. Many used their hair to heighten their awareness and special abilities. There's a story about how Native Americans were used in the Vietnam War as trackers because of their sensitivity to subtle changes in the environment and their intuitive abilities. But once their hair was cut off for the military, all of their abilities went away. In the Ayurvedic beliefs, hair is strongly linked to the nervous system--so strongly that the condition of the hair reflects the state of balance of that person's nervous system. It's said that very dry, wild hair is related to anxiety, and prematurely greying or balding is a sign of high stress and even anger. Ayurveda sees hair as an extension of the etheric spine, acting like the antennae for the energetic world around us. It not only absorbs nutrients like vitamin D from the sun but also the universal life force that increases our vitality and intuition. The longer the hair, the stronger a connection you have to the energetic vibrations. They believe that cutting your hair is cutting the connection to the environment. Many cultures believe that keeping your hair long increases sensitivity, health and spirituality. Many ancient and native people wouldn't voluntarily cut their hair unless for mourning purposes, to retreat from the world, or hygiene purposes. In some cultures, short hair was a sign of defeat or slavery. In religious cultures, hair is often hidden by women protecting their beauty and showing modesty. There are even some mystic ideologies about why women cover their hair and it goes back to hair being an antenna and protecting themselves from negative energy. In modern times, hair is viewed as nothing more than an accessory to fashion. Both men and women cut their hair regularly, depending on what trends are in. Even now, our hair relates to our emotions, depending on what type of day you're having. Ever had a bad hair day? Didn't you feel less confident or unmotivated to carry on that day? It's amazing how connected we are to our hair, especially since it is nothing more than "dead cells." It's part of our every day, whether it's part of your look or even your security blanket. There's so much more to it than that; a whole new sense that we aren't fully aware of. Either way you look at it, hair is a part of us and has a greater purpose than being "just hair."
