How many hours should you sleep for?

Sleep is a very important part of our day, but with the pressures of modern society and the pace of our lives today, we may find ourselves getting less and less of it each night.

The amount of sleep each person needs can really vary.

Some people swear by a schedule of 8 hours every night, whereas others get by with only six and are fully functioning. Then you hear of entrepreneurs like Elon Musk who work over 80 hours a week to run billion-dollar empires, sacrificing sleep in the process.

It begs the question: how many hours do we really need?

It can be a personal thing, however there are some guidelines.

The role of sleep on you

Sleep is a natural human function that is part of our regular routine for health and well-being. Throughout the night, our minds are able to rest while our physical body repairs, and sufficient quality sleep leaves us refreshed and ready for another day.

When we are well rested, we are able to function better however, when we aren’t, we can suffer from daytime tiredness, frustration, a lack of concentration, headaches and much more.

To obtain sufficient sleep, you need to give your body enough hours in bed.

How many hours of sleep do we need?

There is no definitive number as medical opinions and research varies slightly.However, generally speaking, the average healthy adult requires approximately 7 to 8 hours per night, with a range from 5 to 10 hours.

This can vary with age. For example, teenagers need between 8 to 10 hours of sleep every night, and as people approach their seventies, sleep requirements drop by an average of 1.5 hours.

The National Sleep Foundation (NSF) recently reviewed their recommended hours of sleep each night, to produce the following guidelines:

  • Newborns (0-3 months): 14-17 hours
  • Infants (4-11 months): 12-15 hours
  • Toddlers (1-2 years): 11-14 hours
  • Pre-schoolers (3-5): 10-13 hours
  • School-age children (6-13): 9-11 hours
  • Teenagers (14-17): 8-10 hours
  • Younger adults (18-25): 7-9 hours
  • Adults (26-64): 7-9 hours
  • Older adults (65+): 7-8 hours

Just remember it’s not just about counting hours

In the end, the number of hours is just a rough guide.

It’s even more important to practise good sleep hygiene techniques, such as avoiding technology, stress and bright lights before heading to bed. This will ensure that the hours you’re getting are allowing you quality sleep.

Sleep is not one long period of unconsciousness but actually a series of Non-REM and REM (Resting Eye Movement) Cycles. The best rest comes from sleeping enough hours to complete a full cycle a number of times.
