How many hours of sleep do you really need?

We all know getting enough sleep is a vital ingredient to better health and for more productive days – but how many hours of sleep is enough?

Short answer: the ideal length of sleep is not a one-size-fits-all, but there are recommended sleep times for each age group. Let Sealy walk you through the recommended sleep length at different stages of a person’s lifespan.

How many hours of sleep do children need? Children, from newborns to pre-teens, typically need more sleep than their adult counterparts due to their rapid mental and physical growth. The length of a good night’s sleep for kids at different stages are outlined below.

Newborns (0 to 3 months): typically need 14-17 hours of sleep

Infants (4 to 11 months): typically need 12-15 hours of sleep

Toddlers (1 to 2 years): typically need 11-14 hours of sleep

Pre-schoolers (1 to 3 years): typically need 10-13 hours of sleep

School-age children (4 to 13 years): typically need 9-11 hours of sleep

Aside from the getting enough sleep at night, consistent daytime naps are also essential for children 5 years of age and under.

Teenagers (14-17 years): typically need 8-10 hours of sleep at night 

There is often a change in the timing of teens’ sleep, where they naturally want to stay up later and sleep in. This may lead to lack of sleep if they are allowed to go to bed late, but have school early in the morning on the following day. For this reason, being aware of and practicing good sleeping habits are especially important at this stage. More information on the causes and tips for avoiding sleep deprivation in teens here.

How many hours of sleep does an adult need? At the beginning of adult life, around 20 years of age, the required number of hours of sleep begins to stabilise.

Younger Adults (18-25 years): typically need 7-9 hours of sleep

Adults (26-64 years): typically need 7-9 hours of sleep

Older Adults (65 years old and above): typically need 7-8 hours of sleep

There are adults who get less than their optimal length of sleep due to various factors such as stress, sleeping disorders and late work shifts, among others. Some, however, genuinely require shorter amounts of sleep to feel refreshed; while there are true-blue long sleepers, as well. This is because, as mentioned earlier, optimal sleep length is not exactly a one-size-fits-all and can vary per individual.

With that being said…

How do you know you're getting enough sleep?

To know if you're spending the adequate amount of sleep time for you, the key is to look at how well you function during the day.

  • You're able to focus on tasks during the day.
  • You don't have to rely on caffeine or sugar to have enough energy at daytime.
  • You have no trouble falling asleep at night.
  • You feel refreshed when you get up in the morning.

  • You feel moody or cranky at daytime.
  • You feel tired or sleepy throughout the day.
  • You tend to become forgetful.
  • You're having trouble focusing on tasks.
  • You find it difficult to fall asleep at night and have the tendency to wake up multiple times during the course of your bedtime.
If you're experiencing sleep deprivation, some of the effective ways you can improve your sleep health is by turning off distractions before bedtime, sticking to a sleep schedule and sleeping on a mattress with the right level of comfort for you.

Wrapping it up

You can use the number of hours outlined in this article as a guide to compare your sleep length to generally recommended sleep times.
