Sleep physiology and wakefulness

In general, most of the adults take 7-8 hour per day. Timing, duration, and pattern of sleep vary from person to person. This pattern may be affected by age also. This also disturbed by an environment, drugs or due to some illness. Studies by the University of California proved that 3% of people feel good by 6 hours of sleep due to a gene they have. This prepares us for whole day energy and relaxation. During sleep, our muscles have time to repair and release of hormones needed for growth and development.

States and stages of sleep

Two states 
 (1) NREM- nonrapid eye movement sleep. NREM  has 4 stages. Both of these two make a cycle. NREM  75% of night and REM 25% of night time.
When we fall asleep first we enter in NREM. It has 4 stages;

Light sleep
Stage 2
Heart rate and respiration become regular
Stage 3 and 4

            Repeat after every 90 minutes. During this time brain become more active. We see dreams. Energy to brain and body increases One third of our life we spend in sleep to stay fit for rest two third of life. So good sleep is necessary for health. This affects our looks, energy level and performance. So quality and quantity both are important.
