How many hours of sleep is optimal?
I used to sleep 8 hours a night and would always get tired after being awake for 16 hours.
Once I started setting my alarm for 6 hours now I do not get tired until being awake for 18 hours.
I do not feel different throughout the day aside from getting up in the morning.
Has anyone else noticed anything similar? Is there a name for this effect? Any relevant studies or wikipedia articles?
There is something which some studies agree on but in absolute sense it actually feels good to most of adults.
Sleep 6 -8 hours then mandatory sleep 1 - 2 hours at afternoon... I don't do that anymore.. I have too much free time and I tend to either don't sleep or sleep too much,..but when I'm working or in education I do exactly what I wrote above and quality of life skyrockets.
Should I really try having 1-hour naps every single day to reduce fatigue?
I really want to maximize my alertness because fatigue is the biggest impairing factor in my life.
How long does it take for exercising regularly to increase overall alertness? (Jogging/running and light weightlifting) It feels like having to go through quite a period of just increased fatigue and weariness due to physical exercise.
I remember one my back hurt and I had trouble falling asleep properly all night. I am pretty sure I have slept for short periods throughout the night, but I clearly remember being "awake" for most of it.
Then in the morning I woke up and was full of energy like never before. Didn't feel drowsy at all, I straight up jumped from bed and felt really energized. It was a good day. But how did it happen? I barely slept that night.
