The True Value of Sleep

When is it better to go to bed and when do we get the best quality sleep? After scouring the internet for hours, I’ve found that it’s best to go to sleep as early in the evening as possible. Multiple sources and studies (Check out this one and this one) have confirmed this, and I have made a little chart based on what I’ve found.

Value of Sleep

It is also important to consider how you natural body clocks work and the cycles that you sleep through (called the REM/Non-REM sleep cycles). I’ve written a little bit about those already (and here), but basically the key is to not interrupt your sleep. If you do have to wake up even though you haven’t gotten your recommended 8 hours, it’s alright as long as you wake up in between the 90-minute cycles. Here is how they look like if you go to  bed at 10 pm :based on this schedule, it’s easier to wake up at 11:30, 1 am, 3:30 am, 4 am, 5:30 am, etc):


That being said, this doesn’t mean that you will feel as feel as if you slept the full night. This only implies that it will be easiest to wake up at those 90-minute increments. To feel fully rested, it’s best to get at least 8 hours of sleep every night.

If you are interested, here are some great apps I was recommended:

  • Sleep Cycle – a super fancy app that tracks your brain activity while you sleep, analyzes it and even works as an alarm. Available for iPhone and Android
  • Sleepy Time – doesn’t work as an alarm yet, but can calculate the approximate time when you have to wake up or go to bed based on what time you go to bed/wake up.

Off to get my beauty sleep now!
