Sleep - a Miracle to Healthy Life

Sleep is a word that is defined differently by different people. When a human is born, the baby is said to be kept sleeping for 12-15 hours, which is essential for his growth. But, as we grow older and older, the sleep pattern changes over time, and we end up getting only 5 to 6 hours of sleep every day.

Sleep, as we say, is a state in which all our body mechanics come to a rest position. Sleep consists of REM cycle in which the person does rapid eye movement, where we can say that the individual is dreaming and is completely sleeping. This REM is very much essential to complete the sleep cycle. Recent studies have found that an adult needs a complete 7 to 9 hours of sleep per day. Nowadays, people are getting too busy in their work life that they are not getting much time for good sleep. This has become a routine part of everyone’s life, but they do not realize the consequences they have to face in the next 5 to 6 years because of such negligence.

Sleep will always remain of paramount importance for everyone, and everyone should get a minimum of 8 hours of sleep no matter how important is the work next day or how urgent you are supposed to reach your office next morning.
