Coffee can easily cause insomnia, but used coffee grounds can cure it

Coffee can wake up the brain and easily cause insomnia, but the coffee grounds after drinking have the opposite effect and can help you sleep. The specific method is to dry the used coffee grounds, wrap them up and put them in the pillow. You don’t need too much, as long as you feel that the smell is comfortable.

This is because coffee contains caffeine, chlorogenic acid, trigonelline, carboxylic acid, melanoidin, etc., as well as furan and furanone, the smell they emit helps with sleep. But the concentration should not be too high, as it may make people feel excited and not conducive to sleep.
