What keeps you awake at night? 4/5 (1)


In recognition of the fact that good sleep is one of the most necessary ingredients to good health, Australia celebrated sleep awareness week from 4th to 10th July.

About sleep:
Sleep is guided by our bodies’ circadian rhythms, being activated automatically every 24 hours. Sleep does not have a static nature. A person undergoes different cycles of sleep in one night. We move on from light sleep to deep sleep to REM (Rapid Eye Movement) sleep and back again every 90 to 120 minutes. The cycle repeats every one and half to two hours.
Each type of sleep is important. REM sleep activates the learning area of our brain and causes dreams. Non-REM sleep is important for resting, repairing and growth of the body.
