There is no substitute for adequate sleep to maintain physical and mental health. But sleeping too much is just as bad for health as sleeping too little. Again, the need for sleep in childhood, adolescence, youth, youth, and old age is also different. The US National Institutes of Health has recently published age-based sleep time guidelines based on several studies. Here are age-specific bedtime recommendations from The Guardian.

Eighteen researchers from the US National Sleep Foundation developed these age-based sleep guidelines. The country’s sleep experts finalized the guidelines after reviewing 320 research reports conducted over the years.

In developing this advisory, they also examined the health benefits and risks of sleep. A few nights of sleep deprivation can leave you feeling tired and distracted and can lead to depression and anxiety. If this sleep deprivation continues, the risk of diabetes, high blood pressure, and stroke may increase. On the other hand, regular oversleeping can increase these health risks.

Sleep needs also differ in childhood, adolescence, youth, and old age. For example, children need a little more sleep than elders and adults. How much sleep is necessary for a person according to age? The National Sleep Foundation of the United States has published a report on this.

Know how many hours you should sleep at any age.

* Babies aged zero to 3 months need 14 to 17 hours of sleep.

* Babies aged 4 to 11 months need 12 to 15 hours of sleep.

* Children aged 1 to 2 years need 11 to 14 hours of sleep.

* 10 to 13 hours for 3 to 5 year old.

* Children aged 6 to 13 need at least 9-11 hours of sleep. But even if they can sleep properly for            7-8 hours regularly, they can continue themselves.

* 14 to 17-year-olds need 8-10 hours of sleep.

* People aged 18 to 25 need 7-9 hours of sleep daily.

* People aged 26 to 64 need 7-9 hours of sleep daily.

* People above 65 need 7-8 hours of sleep.


Health science says people can survive for 14 days on a hunger strike. Can’t survive more than ten days without sleep. So sleep is essential to keep the body healthy, work well, and recharge the brain. Lack of sleep will also make you mentally ill. And with adequate sleep, the body, mind, and brain are usually ready to work. As a result, work performance or output is better.
