How Much Sleep Do You Really Need? Exploring Science And Habits

I think people make too much of a big deal about sleep. Sure, you need some, but 8 hours? I function just fine on 5-6 hours most days. Anyone else feels the same? Or am I just lucky?

Actually, there’s a significant amount of research showing that consistently getting fewer than 7-8 hours of sleep can have detrimental effects on both cognitive function and long-term health. Sleep isn't just about feeling rested—it's also when your brain consolidates memories and your body repairs itself.

That’s interesting! But how does it actually work? I mean, why do some people seem to do just fine with less sleep while others really struggle? Is it just genetic or can we train ourselves to need less sleep?

 

[adamhholmes]

There’s no real way to "train" your body to need less sleep. It’s mostly genetics, as you mentioned. Some people are naturally short sleepers, but they’re rare. The majority of us need that 7-8 hour range to function optimally. If you think you're doing fine on 5-6 hours, you're probably building up a sleep debt that will catch up with you eventually. Trust me, I’ve read a lot on this.

That’s super useful info!! But do naps help with sleep debt? Asking for a friend

 

[petter]

Napping can indeed ameliorate the effects of sleep deprivation to some extent by facilitating short-term recuperation of cognitive faculties. However, the fragmented nature of napping doesn’t allow for the deep, restorative phases of sleep like REM, which are essential for memory consolidation and overall recovery.

I’ve tried napping too, but it’s hit or miss for me. I read somewhere it’s about timing—like don’t nap too long or too late in the day. Not sure where though

Some people say naps help them, others just feel groggy. Seems like there’s no one-size-fits-all. But hey, whatever works for you, right?

Actually, the science of naps is pretty clear. The ideal nap length is about 20 minutes to avoid entering deeper sleep stages, which cause grogginess (sleep inertia). For longer naps, aim for 90 minutes to complete a full sleep cycle. Timing is everything!

Yeah, but not everyone can fit a "perfectly timed" nap into their day. Most of us are working 9-5, and a nap is just not practical. Plus, isn’t it just better to fix your nighttime sleep?

OMG Jason, I didn’t know naps had science behind them! I’m so trying this 20-minute thing tomorrow!! Thanks for sharing!

While naps can help, they’re not a substitute for quality nighttime sleep. REM and slow-wave sleep, which occur during longer nighttime periods, are essential for functions like emotional regulation and learning.

Emotional regulation? You mean my cranky Monday mornings aren’t just because I hate Mondays? Thanks, Greg! Now I can blame science!

Greg, can you explain why REM sleep is so important? Like, what happens if someone consistently skips it?
