On having trouble waking up:
“It’s either because the quality of sleep you’re getting is bad or you’re waking up at the wrong time. Sleep runs in roughly 90-minute cycles, so if you get up after eight hours, that’s not part of a 90 minute cycle. Sometimes, sleeping less is better. However, sleeping more than nine hours every night can mean two things: depression or narcolepsy. In general, a human body is not meant to sleep for more than five 90 minute cycles. People love to sleep but usually, there’s a reason and the main question remains, are they trying to escape reality? People need to figure out how many hours of sleep they need and get it on a regular basis. If not, along the road, they are going to pay for it. There are studies and data out there that show that if you’re sleep deprived, cancer cells can multiply faster.”
Solution: Pick a wake-up time, then count back seven and a half hours and let it become your bedtime.
