The fact the matter is that different individuals require different amounts of sleep. In this article we shall take a brief look at this aspect.

The need for sleep

Sleep is a time when the body is able to completely relax and tissues have an opportunity to rejuvenate. Every person requires a minimum amount of sleep every day that can help them perform any form of activities that they are involved in optimally.

People who follow sedentary lifestyles may not require a great deal of sleep while those who have extremely active lifestyles and are involved in a great deal of physical exertion may require longer duration of sleep.

If adequate sleep is not achieved, individuals may go into what is known as ‘sleep debt’ – a condition where there is an accumulation of hours of sleeplessness that have amassed over a period of time.

How much sleep do we need?

The National Sleep Foundation has recommended different hours of sleep for individuals of different age.

For example, newborns between 0 to 2 months require up to 18 hours of sleep a day.

Toddlers between 1 to 3 years require between 12 to 14 hours of sleep a day.

Teenagers require between 8.5 to 9.5 hours a day while adults over the age of 18 require 7 to 9 hours of sleep a day.

The bottom line with the requirements is that there is no fixed number of hours that each and every person needs to follow when it comes to sleep.

However, there is plenty of evidence that getting adequate amount of sleep every night can help keep an individual alert and maintain optimal physical performance. This sleep pattern must be followed on a regular basis and any deviation from what the individuals normal sleep pattern is can result in sleep debt and an alteration in the normal circadian rhythm.
