Reply to comment by Fabulous-Relative333 in Too much or too little sleep could be making you sick more. Those who reported sleeping less than six hours a night were 27% more likely to report a recent infection, and those who reported more than nine hours sleep were 44% more likely to report one. by MistWeaver80

This is reverse causation. Those people that are ill or have sleep issues like sleep apnoea need more sleep. If those people had normal amounts of sleep they would have even worse health outcomes.
