How This Works (and why it matters)

Why Timing Your Sleep is Kind of a Big Deal

Ever wake up feeling like you barely slept, even if you got a full eight hours? Yep, that’s because sleep isn’t just about how long you snooze, it’s about when you wake up.

Our brains go through sleep cycles every 90 minutes. Waking up in the middle of one? Total sleepy mode. But if you wake up at the end of a cycle? Ding ding! You feel way more refreshed, even with less sleep.

This calculator helps you find those magic times so you can wake up like a well-rested superhero.

What’s a Sleep Cycle, Anyway?

What Even Is a Sleep Cycle?

Great question! While you sleep, your brain travels through different stages, light sleep, deep sleep, and REM (that’s dreamland). A full cycle takes about 90 minutes, and we go through 4 to 6 cycles a night.

So the key? Try to wake up at the end of a cycle instead of smack in the middle of one. That’s what this little calculator is here for, your own personal bedtime whisperer!

How Many Sleep Cycles Do I Need?

How Much Sleep Should I Actually Get?

Most people need between 7.5 and 9 hours of sleep (that’s 5–6 full cycles). Here’s a quick guide based on age:

Age GroupRecommended Sleep
Kids (6–13)9–11 hours
Teens (14–17)8–10 hours
Adults (18–64)7–9 hours
New Parents 😅LOL, good luck
