I really like that you emphasised the circadian clock as well as talked about the mental health issues around irregular sleep.

We all assume that we can simply beat the clock and sacrifice our sleep to "buy" some more time in a day, but at what cost? People speak about the effects of lockdown and mental health like it's in vogue because of the lockdown measures, but millions of people around the world are constantly screwing up their body chemistry through chronic sleep deprivation day in, day out.
