I was looking up things for shifting circadian rhythms, because I've been up nearly til dawn since getting back to Waterloo, and I found these, which also are maybe good for SAD.
Figured I'd tag @byudkowsky & @Meaningness, & @ESYudkowsky I suppose!https://www.re-timer.com/benefits-for/seasonal-affective-disorder-sad/ …
Thanks! I’ve been aware of these sorts of things (there’s several similar brands), but I can’t find much in the way of people saying “yes, works for me!” So I’ve counted it as “intriguing, may be worth experimenting with” but not gotten around to trying.
