Asap SCIENCE's latest video takes a look at sleep and how much of it allows for us to be productive, or even merely functional. I'm sure nobody is surprised that the news isn't good for people with a newborn in their house. The concept of sleep debt is also discussed. This morning I feel like my sleep debt has accumulated to the point that, soon, someone's Uncle Vito is going to whack me.
So, again, it's one of those things that it's not the same for everyone. And I'm happy to not sleep much.
Even amidst stress, I'm able to just "turn-off" and sleep at will - whenever I want. So if I have time to sleep now, and will be doing something later when sleep is not convenient, I'll just sleep. Can also tell myself when to wake, rarely use alarm clocks.
One must take caution to the research the video quoted, as most of them are not random trial based. People sleep less maybe because they have more work, or greater mental pressure due to family/work issues, which is the real reason that leads to their higher risk of disease and death
