How to wake up fresh with a smarter alarm

Most of you might not know that your brain is in various phases while you sleep. Yes, even if you think you are a deep sleeper, you aren’t in the “deep sleep” stage the entire time you are in the bed. The brain alternates between various stages and there are times when you are in deep sleep and times when you are in the light sleep stage.

The problem with traditional alarm clocks are that it is based on a fixed time and what stage you are during that time is totally dependant upon what time you started sleeping (not what time you went to bed). Waking up to the “nuclear warning” sound of your alarm clock while you are in deep sleep is the worst way to begin your day.

You can wire up your brain and monitor what stage you are in and ask someone to wake you up at the right moment. But It is too costly and no human would be willing to monitor and wake you up every single day.

The alternative is to use the various sleep monitoring apps available for your smartphones. These apps use the accelerometer in your smartphone and detect the minor movements you make when during the lightest stage of your sleep. Using that, it can wake you up at the right stage and you would wake up refreshed and not wanting to kill everyone.

The app I use is SleepTime by Azumio, which is available for both iPhone and Android phones. All you have to do is set up a Alarm Time by which time you “should” wake up. The App chooses a 30 minute window before the set time. Whenever you are in the lightest stage of your sleep within that 30 minute window, it wakes you up. It also has nice graphs of your sleep stages and how often you woke up, etc. It is interesting if you love to measure metrics about everything.

The alarm sound is also very light and pleasant sounding (much relief to my wife) and since you are in the lightest stage of the sleep, even the lightest sounds is enough to wake you up. I tried similar apps long time before but the old android smartphones were more of a battery extractors and the phone died out before I could even finish a night’s sleep. Constantly monitoring the accelerometer is a battery drain.

But nowadays batteries are much better and on my iphone I lose about something like 20% of battery from a fully charged state. I did try this app many days and I have definitely been woken up at the lightest stage of my sleep to the lowest volume. There was an exception on a day or two, but that was because I was too tired to wake up because of not enough sleep (I am a night owl).

If you are a normal living person and want to wake up fresh everyday, do try SleepTime. You would notice a small difference in how you wake up.
