Recently, I realized that some days when I wake up, I find myself feeling alert and able to step out of my cozy bed. But on the other days, I can only manage to tap snooze on my alarm before my alarm tone gets too crazy.
So, I decided to find out the reason behind this.
And to my surprise, I came upon this interesting 90-minute wake-up rule. As you must've probably learnt this in school, every night, your brain moves through several sleep cycles. At the start comes the light sleep mode, then the deep sleep mode followed by the dream cycle, and then again back to the start- light sleep.
This entire process takes about 90 minutes. So, you will feel the most alert and refreshed if you wake up at the end of the cycle as opposed to the start or the middle of it. Why? Because that’s where you’re closest to your normal waking state.
What I did next was fixing a time when I wanted to wake up, say 7 a.m. I google up few tools and found this amazing sleep cycle calculator which I am now using. I then counted back in 90-minute blocks and figured out that I had to get to sleep by 11:30 p.m. or 10 p.m.
And voila, I now wake up without snoozing my alarm a hundred times.
Have you ever tried experimenting with this method before?
