For me it was “buy high quality pillow” because you sleep for one thrid of a day etc. I needed a new pillow anyway so I came to the store and bought the best they had. And it was … ok. Like it’s a fine pillow but my sleeping haven’t improved really, it’s basically the same. So I was disapointed :(
So, which life pro tip disappointed you?
I have sleep apnea and I have found a bumper belt works wonders. It’s a belt you attach to your back with several air bladders that keep you on your side, even if your body is included towards back sleeping. It travels very nicely. Just deflate the bladders and roll up the belt.
Luckily I don’t need anything like a bumper belt. I have trained myself to never end up on my back; to always turn a full 180° from one side to another no matter how deeply I am sleeping.
I’m able to do a number of nifty things like this in my sleep. Such as being able to wake up within 2-3 minutes of a set time, without an alarm or even a clock, so long as I get more than 4-5hrs of sleep. I’ve even been able to do it with less sleep, only with less than perfect reliability.
It’s a form of mental feedback that I do before falling asleep, and across enough days it ends up being trained in such that I don’t have to reinforce it every night.
