We all wish to be a morning person and get that productivity going for us, right? While this 90-minute snooze did not make me a happy morning person right away, safe to say, I don’t feel like hitting the bed again the moment the alarm rings.Alarms (based on the AlarmManager class) give you a way to perform While the hack did not actually stop me from hitting the snooze button a couple of days, it did make me feel well rested. A few days into it, I actually felt like I had more energy in me and got work done faster in the morning chaos, which was so dreadful. I felt like I had actually woken up early. By the time I actually had to wake up for the day, I was a little bit less tired than usual. When my 90-minute alarm rang, I got up, had some water and went back to sleep because I had so much more extra time to sleep. Safe to say, the experiment was a fail on the first day. When it was time for the next alarm, I could not get up on time and snoozed for another 10 minutes. For day 1, I set an alarm a whole 1.5 hours before my actual wake up time and got back to bed quickly forgetting everything about the hack. Did it work? It wasn’t very easy to get into the new schedule. The 90 minutes of ‘extra’ sleep we get between snoozes is actually a proper sleep cycle, allowing you to wake up after getting REM sleep and not in between. ![]() Instead of wasting time hitting the snooze button and sleeping for broken, fragmented bits which can end up harming you, the hack simply requires one to set two alarms, one for 90 minutes before and the other when you actually have to wake up. When you wake up in the middle of a deep sleep, we end up feeling exhausted, tired and grumpy - because we feel we did not get proper sleep. The science behind the 90-minute rule The 90-minute snooze rule is based on timing the bedtime in a way that we wake up at the end of a sleep cycle - which has 90 minutes of proper REM sleep. For one, this hack did not want me to change my lifestyle and hit the bed early but just set the alarm back by precisely 90 minutes. Everyday, I say to myself I will wake up early but what’s the use? So when I tried searching if the internet could solve my troubles and wake me early, I got curious about a scientific hack. What follows is a huffed up morning routine, running from one room to another just to get things done quickly and rush out of the house. Even on days I clock in 8 full hours, I feel grumpy and tired. Every morning for me is a case of setting three alarms, one ten minutes before, one four minutes before and one for the actual time and yet it takes a lot of courage to get out of the bed. No matter how early I go to bed and how long I stay in the next morning, the amount of sleep I get is never enough. ![]()
