Since bootstrapping my own sleep aid startup (https://trycosmo.com/), I've been surprised at the lack of priority society places on sleep in general. Better sleep would help patients recover better and shorten hospital stays. The inability to sleep, especially in the ICU, likely results in tens of thousands of unnecessary secondary infections and deaths per year.

I like the author's approach of simply refusing to give blood at night. My guess is that hospitals default to checking vitals so frequently to avoid liability-- could you imagine the headline if a patient died because his vitals had not been checked for eight hours?

A simple "Do not disturb" sign for patients would resolve all of these issues.
