Sleep is a
physiological process that occurs in humans and animals and is defined as a
recurrent state of reduced attention to the surrounding environment. The most
important functions of sleep are the restoration of body functions, synthesis
of proteins, and the prevention of lethargy. The number of sleep hours required
varies from individual to individual.
An adult person needs 6 to 8 hours of
good sleep daily to be alert during the day.Today the inability to sleep plagues millions
of people. Sleeping pills, including tranquilizers, represent the most
prescribed group of medications. Rather than simply treating the symptom,
nutritional research reveals that biochemical causes of insomnia can be
addressed by nutritional therapy, often resulting in permanent alleviation of
sleep difficulties.
