Getting by on less sleep
I've been sleeping alot less lately, sometimes 3 hours. On these days, I'm not OVERLY tired. On days that I sleep 6, 9, or more hours (weekend), I'm in a permanent stupor. I'm guessing that making up for lost time is negatively effecting me.
How can I get by on around 4.5 hours of sleep effectively?
What can I do to improve the quality of the quantity of sleep that I get?
Will one be more rested in a cold or hot environment?
