> And those studies suggest that melatonin plays a critical part in your circadian rhythm, which kind of implies that adding it to your food would also screw with your circadian rhythm. That alone seems like a good enough reason to caution against adding it into the food supply.
I think you're correct. But electric light also screws with your circadian rhythm, and that's a concern almost nobody takes seriously. Years back I built my own automated lighting system [1] and the biggest thing I learned from it is that I'm not a responsible lightswitch user. My sleep schedule used to be very chaotic. But once I set up my screens and my house to dim and redshift in line with a regular day-night cycle, I not only started sleeping very regularly, but my mood and focus improved.
When electric lighting was introduced it notably changed sleep schedules. [2] But we got used to that and just kinda went with it, even though surveys show massive problems with sleep. For me now it's a cautionary tale about how little we understand the impact of technologies we adopt.
