happiest: Yes, it helps for adults too, I tried it a couple times, fell asleep pretty much after that, It is healthy, and safe.
I might add, that aries2756 brought up very simple but clever questions to ask yourself. For example, the other night my son couldn’t sleep until I realized he put on his new valore PJs and his room was much too hot! Sometimes it could be a simple solution. I drank Pepsi 3 hrs before going to bed, (I never drink soda)and the caffeine kept me up for hours, literally!!
