Sleep is a natural occurring state of all human being during which all the organs are at rest. The mechanism and purpose of sleep are not clearly understood by scientists even now and different theories and explanations are being evolved.  But sufficient and sound sleep very essential for every human being for the brain to be healthy and be able to work properly. The time of sleep and the amount of sleep that a person gets daily is very important. Normally people sleep from 22.00 to 6.00 or 7.00. Eight hours sleep per day is considered to be the optimum quantity of sleep required by a grown up adult. Good sleep hygiene can lead to improved quality of sleep. Avoiding emotional conflicts before the hours of sleep, going to sleep and awaking after sleep at a constant pre fixed time, sleeping in cool, dark place without any illumination, daily exercise and avoiding heavy meals before sleeping etc are some good practices which can be helpful in producing sound sleep.

As a result of the blockage to the air way, a part of the air inhaled by a person gets blocked. This air goes out through the mouth instead of going to the lungs. The air that goes out through the mouth produces a negative pressure and causes vibration of the soft palate producing the sound known as snoring.  Occasionally, every one snores. But if the snoring becomes frequent it may affect the quality and quantity of the sleep of a person and it can cause irritation to your family members and roommates. Snoring leads to daytime fatigue, irritability and health problems. Sleep apnea is a disorder in which your breathing during sleep may be disrupted for at least 10 seconds. Another form of sleep apnea is central sleep apnea in which breathing in your sleep is not properly controlled by the brain. The prevalence of snoring habit is considered to be 2 to 3 % among the general population which increases to 10 to 20  % among children
