Why does the body naturally wake up around the same times every day without any prompting, even if it hasn’t been 8 hours?
In: Biology
It’s the external stimulus that sets you to 2 hours cycle. I remember reading an article long ago about an experiment. A guy with supplies were sent to live in a cave, isolated with no clock and nothing for many days. Eat when he’s hungry, sleep when he’s tired, etc. Over time he started having 30-hours cycle rather than traditional 24 hours.
You would have different time if you lived in rural area with telephone turned off, no traffic, no other people around, etc.
