Heart attacks go up by 23% in spring(when we lose an hour) and down by 23% (in fall when gain an hour). That how important an hour of sleep is
This reminded me of rupert sheldrake's book "the science delusion". He tells a story about a scientist that, after much prodding" finally admits to him the force of gravity ("G" as i learned it in my physics class) isnt really a constant but was consensus-ed into being one.
A guy on Joe Rogans podcast said this. It usually takes several days to readjust to the time change so most people lose an hour of sleep
