So, your training and nutrition are both on point, but you still don’t perform the way you want? Poor recovery  habits, like a lack of sleep, may be to blame. So how much sleep do you need in the first place?

In this series, we’ll take a look at some of the most common questions about sleep.

Most of us know that getting enough quality rest is important, but, far too few of us actually make shut-eye a priority. In fact, the Centers for Disease Control and Prevention estimates that nearly a third of adults sleep less than 7 hours per night. This lack of sleep leads to increased fatigue during the day, lower energy in training, and decreased ability to focus at work and at home.

To complicate matters even more, blue lights, caffeine, and other stimulants are interfering with our natural sleep/wake cycle, also known as our circadian rhythm. For those struggling with excessive sleep debt, it can be hard to remember what feeling truly rested is even like anymore.

You may have heard that too much or too little sleep can both have negative effects. But, the amount of sleep you need exactly depends on your genes, age, health status and lifestyle factors such as stress, level of physical activity and work schedules.

Newer recommendations from the National Sleep Foundation provides an optimal window of time for different age groups. For adults (ages 26-64), it is recommended to get between seven and nine hours of sleep (but as little as six or as much as 10 may be appropriate).

Here is their general guideline:

6-13 years old = 9.5-12 hours a night
14-17 years old = 8-11 hours a night
18-25 years old = 7-11 hours a night
26-64 years old= 7-9 hours a night

To find the magic number for you, you’ll have to take a look at the bigger picture. If you’re out less than six hours of sleep each night AND do NOT experience negative side effects, you may be considered a ‘short sleeper.’ This would be the only appropriate scenario to sleep less than the above recommended amount.

On the flip side, some people require more than 10 hours per night (‘long sleepers’). But only if no negative side effects occur.
