The Importance of Sleep
During sleep, the pineal gland and the hypothalamus in the brain stimulate the secretion of melatonin, human growth hormone, and other substances that allow the body to rebuild muscle tissues and put the neurotransmitter receptors to rest. From these two basic functions of sleep spring the long list of preventive and restorative health benefits.
* In newborns, REM sleep helps develop the central nervous system.
* It enables the body to repair itself and regenerate.
* It helps the brain organize and store memories.
* It restores the body's energy.
* It reduces risks of cardiovascular disease, diabetes, obesity, and anxiety.
* It allows the brain to recharge.
The Brain and Sleep
Adenosine is a nucleoside composed of a molecule of adenine attached to a ribose sugar molecule which passes signals to the brain when the body needs rest. It is an inhibitory neurotransmitter, believed to play a role in promoting sleep and suppressing arousal.
Adenosine triphospate (ATP) releases energy to fuel reactions. With each burst of energy, ATP loses it triphospate molecule, and the adenosine binds to receptors. Rising levels of adenosine signal to the brain that the body needs rest. A person needs to get the proper amount of sleep (7 to 8 hours) daily in order to function well. It is directly related to the body's physiological functions, emotional balance, and mental performance.
