Caffeinated Drinks

Caffeinated drinks including soda, coffee, and tea are among the worst foods for sleep health. Caffeine perks you up and improves your mental sharpness, which is why many people start their days with a cup of coffee.

According to research published in Risk Management and Healthcare Policy in December 2018, 90% of American adults reportedly use caffeine-containing beverages on a regular basis. Unfortunately, consuming a lot of caffeine or drinking it too late in the day can disrupt your sleep. When people don't get enough sleep, they frequently turn to caffeine to make up for it, which leads to a vicious cycle where they depend on it to stay up during the day and are then too linked to sleep at night. Drinking even one cup of coffee within a few hours of sleep is a bad idea, because caffeine has a half-life of about five hours for most people.
