What Exactly Are Sleep Recommendations Based On, Anyway?

Everyone needs to sleep, but everyone sleeps differently. And it’s been known for a while that the 8-hour sleep advice doesn’t fit all.

But what determines the amount of sleep an individual needs? One way to find out is to look at groups of people with different sleeping habits, and see which groups end up healthier and more productive. For example, studies have found people who have insufficient sleep are at higher risk of becoming obese or developing Type 2 diabetes, according to the Centers for Disease Control and Prevention. On the other hand, too much sleep has been linked with higher risk of heart disease and premature death.

Recently, the nonprofit research group National Sleep Foundation (NSF) set out to distill the findings of research into guidelines for sleep duration. The foundation gathered a panel of 18 sleep specialists and experts in medicine and physiology to review existing scientific literature on the effects of sleep duration on health, performance and safety.

The group looked at 312 studies published between 2004 and 2014. These studies looked at the link between sleep duration and topics ranging from memory and learning, to risk of accidents, to mental health and medical problems. Ultimately, the group came up with new guidelines for sleep duration, broken down by age groups. The new recommendations, which were release in January, also include a two to three-hour range of healthy sleep times to account for individual differences.
