Can you clarify what that graph is saying? It looks to me like it shows that ~4 hours of sleep has the same all-cause mortality as 8 hours of sleep, but that can't be right...
It does make sense to me. Example - miles per gallon. If you graph efficiency, the most efficient mpg is ~55 mph for a standard sedan. As you move further from the most efficient point in either direction, the efficiency declines. So a sedan may have a peak efficiency of 40 mpg at 55 mph. However, at 35 mph and 75 mph, the efficiency drops to 30 mpg.
Applying the same approach of mpg to sleep and all-cause mortality, it makes sense that there is a high end and low end of sleep duration that would have similar effect. In this case, it happens to be 4 and 8 hrs 🤷🏽♂️.
I enjoyed this sleep article. Managing sleep is interesting to me because there are many variables that impact it and I feel my sleep quality has worsened as I have aged. I am will be flying to Greece in a couple of weeks and my concern is dealing with jet lag. I am trying a few things to minimize the impact of jet lag so I can hit the ground jogging (vice running) when I get to Greece.
