Monday through Friday our smartphone alarm clocks devotedly drag us out from the irresistable morning sweetness navigating us right into the shower and then to the coffee maker. But did you know that you can calculate your perfect bedtime to wake up in the right sleep cycle?
While many complain about the lack of shut-eye, you are just about to find out the only right way to wake up refreshed, look sharp, and stay alert all day long.
Ready, set, go!
Our sleep cycle consists of deep sleep and REM-sleep (Rapid Eye Movement) that take turns with 90 minute intervals. After we turn off the light and embrace out pillow, it normally takes from 5 to 25 minutes for us to fall asleep. That’s when our eyelid movements and breathing get slower gradually turning into what is called deep sleep.
During deep sleep, your body transports blood away from your brain to let it rest. Therefore, if you wake up in the deep sleep period, you will feel irritated and grumpy. With age, deep sleep cycles get shorter increasing your chances of waking up in a good mood after you turn 50.
REM-sleep appears on the scene in roughly 90 minutes after the deep sleep starts. REM features rapid eye movements, quickened breathing, and dreams that can at times be so different. REM sleep cycles grow in length and can vary from 10 to 60 minutes. This is the stage you want to wake up in to feel naturally refreshed without an alarm clock.
