Key takeaways so far
- most of your REM sleep occurs in the latter half of the night, so losing 2 hours of sleep means losing 60-90% of REM sleep
- there’s such a wide variety of sleep in animals. Aquatic mammals sleep with one hemisphere of their brain and the other stays active to keep them alive (such as surfacing to breathe). Brown bats sleep over 19 hours, the most of any mammal
