We all know we should try to get eight hours of sleep a night. But did you know not all sleep is created equal?
There’s some truth to the old adage, every hour of sleep before midnight is worth two after midnight. Studies show that the time of night you go to sleep can significantly impact the quality of your sleep, which depends on getting a healthy amount of both deep sleep (the type of sleep that helps your body recover physically) and REM sleep (the type of sleep that helps your body recover mentally). Deep sleep dominates sleep cycles in the first half of the night, while REM sleep dominates sleep cycles in the second half of the night. Thanks to our circadian rhythm, the shift from deep sleep to REM sleep happens at certain times of night, regardless of when you go to bed.
So, if you’re burning the midnight oil, you may be missing out on the restorative deep sleep your body needs for immune system support, muscle repair, and tissue growth. Start going to sleep a little earlier and see just how capable your body is at healing itself.
