Recently read that wearing a cold/chilled hat or cap at night can help slow the mind down. Have any of you tried that?
Have any of you tried the weighted blankets?
Any other helpful advice will be appreciated!!!

Hello. I have not heard of chilled cap. Sounds interesting. I have some heavy quilts I use sometimes. I think it does help but I also awake to hot flashes at random times.

@bebobaBetty , thank you!
