When I get a lack of sleep (or especially multiple nights of bad sleep), I often have a splitting headache the next day that makes me unfunctional and worsens until I get more sleep. Other people I’m with have the exact same sleeping routines and never get any headaches, and can still function despite being tired. What’s wrong with me?
From my understanding, the science for and against this is still being researched. I know it’s not a 1:1 “catch-up” period, but I believe that you can somewhat balance your sleep debt over the course of several days to some effectiveness.
