As long as I can remember, going to sleep an hour or two later means waking up earlier than normal so I get 5-6 hours of sleep. I didn’t realize there was a pattern until almost 40. And even since it still boggles that it exists. It seems logical that going to sleep later should result in waking later. Maybe at the same time with aid of an alarm. But, for me, it means waking up before the alarm.
Going to sleep too early also means 5-6 hours of sleep. So, if I go to sleep at say 9pm, then I wake up between 2-3am. I probably am fully awake but tired for a few hours. I will crash hard and need another few hours of sleep to feel rested.
Let’s hope this is not genetic.
