On: Sense – Wake up when it's right for you

[arjunnarayan]

I'd add in that you should avoid computer screens (or use some software like f.lux on the maximum dark setting) after the sun goes down. I'd also recommend watching your alcohol consumption in the evening as that significantly disrupts your sleep cycle.

No kidding -- I routinely code late into the night. Each time, I can't fall asleep if I didn't have f.lux on a fairly "yellow" setting.

I (a) wish that something like that was built into iOS and (b) feel bad for people who don't know f.lux exists (or RedShift, for Linux folks.)

f.lux is the only reason I have a jailbroken iPhone. I can no longer stare into other people's phones at night without f.lux
