Discover the magic that happens when you go to sleep

Electrical activity measured in the brain during sleep indicates that healthful physiological changes occur in 90-minute periods throughout the night, which means that the active biological clock in a person is set to operate in a circadian rhythm of 90-minute cycles that repeats every 25 to 28 hours. This clock is set and reset according to the amount of natural daylight available each day, thus evening sleep begins later when we have longer days and shorter nights.
As we tend to wind down from our daily activities sometime after 9:00 p.m., our body temperature falls again, and we are lulled into a state of drowsiness during which the brain converts low-voltage “beta” waves into higher voltage “alpha” waves. As these alpha waves are, in turn, converted to slower “theta” waves during what are known as sleep stages 1 and 2, the skeletal muscles relax, causing the “hypnotic jerk” or “nodding” experience. When nodding off is not resisted or interrupted, the theta waves soon turn into even slower “delta” waves of the third and fourth stages of deeper sleep.
During these stages, rapid-eye-movement {REM} sleep, dreams, and actual muscle paralysis take place. If, for some reason, muscle paralysis does not occur, the vividness of the dream state will physically draw the dreamer into an active state of sleepwalking or, worse yet, intense physical activity that will further break down exhausted muscle tissues already in need of repair.

During undisturbed sleep or slow-wave sleep, the plasma growth hormone (human growth hormone – somatropin – ) in humans is found to be at its highest levels. If the sleep stage process is interrupted, complete repair of soft tissues is impossible due to the resulting decrease or absence of human growth hormone – somatropin – .

Unfortunately, when sleep is altered (reduced or extended), performance and mood are both affected. Achieving that elusive perfect night’s sleep, then, would seem to depend upon enjoying a low-key day in a stress-free environment followed by seeking sleep at a routine time in a quiet, totally dark room…
