You’ve finally had a chance to unwind from the day and are plumped on your sofa watching your favorite television program. As time passes the temperature in the room becomes hotter and hotter, and you begin to feel uncomfortable. As an innate (natural) defense mechanism, your body strives to maintain a comfortable body temperature; also related to homeostasis. Once your brain determines that you’re uncomfortable it commands various systems in your body to find, then push water to the surface of the skin to cool yourself off, creating perspiration. The water (sweat) is taken from within muscle tissues, organs, the bloodstream and even your brain.
According to many studies, muscles, on average, are comprised approximately 70% water, the brain is 80% and blood comes in at 90%; reason why many regard blood as liquid tissue.
This is yet another one of our survival mechanisms Mother Nature has equipped us with to cool us off in hot temperatures. And, in reverse, we’re also equipped to turn up the heat when things become too cold . . .
… You’re still trying to enjoy your favorite show, but now the temperature drops to freezing. Without telling your body to quiver it automatically triggers a homeostatic reaction that provokes your body to shiver and shake while your teeth begin to chatter. All of the shivering and shaking and chattering are the body’s way it can create friction that releases internal heat, much like starting a fire by rubbing two sticks together.
The brain also controls body temperature and hydration levels. So the healthier your brain is the more comfortable and productive your life becomes. And it’s a prudent idea to drink plenty of water and make sure your dwelling has a functional thermostat that compliments the one inside your body!
