Of course studies on the positive effects of bed socks have focused on cool, winter environments
Personally, I hate wearing socks to bed, and if I do, I don’t sleep very well at all. The part of Australia that I live in doesn’t get that cold in winter, but it does get pretty warm and sticky in summer, and wearing socks to bed would only exacerbate the problem.
The actual secret to great sleep is to test out what actually works for you, track your sleep, do a little research on different “methods” of getting good sleep, and experiment with them till you find what works well for you.
I get my best sleep by not drinking alcohol after 4-5pm, walking more than 6,000 steps in a day, and by having a vape before bed. Following this routine, and being in bed before 11pm, I can pretty much guarantee an 8 hour sleep, with a solid 2 hour block of deep sleep.
