Weighted blankets are used for a number of health reasons.

People who have a lot of stress or struggle falling asleep at night benefit from them as well.

Doesnt really say anything - there have been plenty of products that were designed for specific people that ended up being adopted by others because it just was a better product for them as well

Like how Coca Cola was originay created for people with a morphine addiction. Unless morphine addiction became a lot more widespread recently while I wasnt looking.

Hmm… now I kind of wanna buy one.
