Recently we have a wave of resources and posts about sleeping, we introduced some posts on polyphasic sleep, the sleep cycle, and an extensive sleeping reference. I highlighted in the sleep reference that alarm maybe harmful for your sleeping cycle. Here is another experience from Vincent Cheung on alarm clock. He suggested that the alarm clock may wake you up even when you are in deep sleep. He suggested a system that can help this situation:
* Set an alarm to go off before you want to wake up.
* Make the alarm really quiet radio or music.
* Set a second alarm to go off at the latest time you want to wake up.
* Make the alarm the usual loudness.
The whole point is that the first alarm should be so quiet that it will only wake you up if you’re in “light” sleep. The second alarm is the back up to make sure that you wake up in time :).
Quite a smart suggestion. He even used this system for 7 years so I am sure it is quite effective.
Alarm clocks are bad. How to wake up and feel better. – [Vincent Cheung. Hat tips to Venki for the link!]
