It is common knowledge that sound sleep is essential for good health. It is only during sleep that the worn out body tissues are repaired and revived. No gland or organ in the body can function properly unless we sleep well. Deeper the sleep, better is the tissue rejuvenation.
Unfortunately in today’s world, natural sound sleep is extremely rare. People lead a highly stressful life and carry their stress to bed. The brain remains active thinking and analysing the day’s problems. When the mind is thus not relaxed, the body cannot let go of its tension. With a tense body and mind, restful sleep is not possible.
Even if one manages to fall asleep in that condition, the sleep generally is not of high quality. The person keeps tossing and turning all through the night and may wake up a few times during that period. Obviously, the body parts do not get a good chance to rejuvenate themselves well. In such a condition, one starts the day with less efficient glands and organs.
