As I've been doing more deliberate cold water exposure, I've also wondered about the benefits of cold weather exposure - i.e. not wearing a jacket when I'm out and about in the cold. Similarly, I've wondered if I really need to bundle up my young children to go play outside if there are benefits to cold exposure. However, there's a pretty common understanding that cold weather can make you sick. Is this true, or just an old wives' tale?
I am interested in improving my REM sleep specifically. My sleep at the first half of the night is always good, the second half of the night is however hit or miss. Any techniques to address that? I have used Reveri at times, but have not incorporated it as an everyday practice. Would this improve its efficacy in improving REM sleep?
