Is that not almost everyone? I often don't get tired till or 4 am and have to get up not long after that for work.
- kqr 7y agoDo you exercise during the day? Do you avoid strong light and things that excite you when bedtime nears? I think the author is arguing that by using alarm clocks and artificial light and otherwise caving to the expectations of society, we are wrecking our internal sleep clocks and they cannot be trusted for measurements until you have actually removed yourself from all that for a while. That includes your 4 am is sleepytime measurement.
