We’re bombarded with messages about the magic number: eight hours. Eight hours of sleep a night, that is. But what if achieving this perfect eight eludes you night after night? Does it mean you’re doomed to function at a subpar level?
The surprising truth is many people function perfectly well on less than eight hours of sleep.
Here’s the objective truth: sleep needs are individual. While some people truly thrive on eight hours, others function best on six or seven, and some outliers even do well on five!
This fact might challenge what you’ve always believed, but there’s science behind it. Genes play a significant role in sleep duration. People who carry certain genetic variations naturally require less sleep [1].
So, how do you know if you’re one of those who needs less than eight hours?
The key is to pay attention to your body. Here are some signs you might be getting enough sleep, even if it’s not eight hours:
- Waking Up Feeling Refreshed: You wake up in the morning feeling energized and alert, not groggy or needing to hit snooze.
- Sharp Throughout the Day: You maintain focus and concentration throughout the day, without afternoon slumps.
- Physically Capable: You have the physical energy to tackle your daily activities without needing excessive naps.
If you’re consistently getting less than eight hours but functioning well, don’t force yourself to fit into a mold that doesn’t suit you.
However, this doesn’t mean sleep isn’t important. Chronic sleep deprivation (consistently getting less than you need) can have negative consequences. If you’re constantly exhausted, struggling with focus, or notice your mood is suffering, it’s definitely time to prioritize getting more sleep.
