It seems more difficult than ever to get a decent night's sleep and feel good after it. If you'd like to wake up refreshed every morning instead of groggy and grumpy (no matter how little you might sleep), remember the 90-minute rule.

It's all about timing your bedtime so you wake up at the end of a sleep cycle (which is 90 minutes on average) instead of in the middle, when you're in a deeper stage of sleep.
This isn't a new concept, of course. Sleep apps like Sleepyti.me are based on the 90-minute sleep cycle and are designed to help you wake up naturally. While your sleep patterns might not follow precisely this 90-minute rule, it's a good rule of thumb if you're not using sleep tracking apps. The Daily Mail reminds us of this technique of counting back in 90-minute segments from your desired wake time so you know what time you should fall asleep by.
The article also offers other helpful tips like figuring out when to nap and what kind of snorer you are.
