Sleep Loss and Cardiovascular Disease

There's no link between sleeping too much and cancer. There's a couple there's, i think, two or three. Breast cancer is one of them that for whatever reason, people who sleep less are more likely to get breast cancer. But again, we don't know causality. So it could actually be that a precursor, breath cancer, is causing you to sleep less,. r or some third thing is causing both of them. It just feels like a very big bucket to sort of throw everything into without parcing a little bit.
