How to Wake Up Beautifully Every
Day<http://everythinguseful.wikinet.org/wiki/Everything_Useful#How_to_Wake_Up_Beautifully_Every_Day>
I actually never wake up groggy, sleep or no sleep. Sleep science is real!
Try it sometime ;D
(Okay, so once in a while I don't wake up beautifully - but it's almost
always from an alarm-setting mistake!)
The Science:
- The clearest source online:
http://helpguide.org/life/sleeping.htm#cycle
- Your body goes many *sleep cycles* every night, usually about 1.5h.
- You should only attempt to wake up during shallowest part of the
cycle.
- You just need to know what your *baseline* is (where the shallowest
part is).
- Assuming you fall asleep when you lay down, your baseline is
probably something like (7.5h +/- 1.5h)
- Assuming it takes you 14 minutes to fall asleep, this website will
do the math for you: http://www.sleepyti.me/
- This baseline changes depending on how well/un-rested you are, and
that's the hard part to keep track of.
- An example: you snooze 30 min before waking up
- That shows you where the "baseline" is!
- You could change your *bedtime* or your *alarm* to prevent this the
next day. If you snooze 30 min:
- Go to bed 30 min earlier if you can (obvious right?)
- OR try setting your alarm back 60 minutes the next day. It's
magic!
