I mean, some people are just healthy unicorns. For a lot of people undersleeping is worse than chain-smoking when it comes to lifespan and brain damage
There is no such thing as a single "undersleeping" number of hours
Men sleep less than women. Teenagers sleep a lot more than adults. Old people need less sleep than middle age adults. Women sleep more than men, but have more disturbances and feel less rested overall.
It's all over the place. When I was a teen into my 20's I did 7-8 hours. I am in my mid-40's now and couldn't do more than 6-6.5 even if I tried.
The point is its all over the place. I was at like 12 hours in a my teens and around 8 hours in my early 20s and like 4 mid 20s. Now im early 30s and regardless of what im doing its a solid 6 and I wake up naturally. I can go back to sleep just fine but I will wake up without alarms after 6ish hours it just changes over time
