10 Causes of Insomnia
Cause #9: Excess Coffee
Drinking coffee helps you stay alert, which is a good thing during the day when you need to carry out various tasks. But you don’t want such kind of stimulation once you go to bed. You want your body to relax so that you can drift away into a restful sleep.
Coffee contains caffeine, a stimulant that can stay in the system for up to eight hours. This is why drinking coffee at night, or even in the afternoon is not a good idea. In fact, according to the National Sleep Foundation, drinking more than one or two cups of coffee during the day can affect your sleep later in the night. A 2005 study found that people who drink four or more cups of coffee a day were more likely to suffer from insomnia than people who didn’t drink coffee or drank one cup of coffee.
