Caffeine is a legal drug in the US found in coffee, tea, soda, chocolate, and some medications. If you’re wondering why so many people are drawn to coffee and tea, it often has to do with a much-needed caffeine boost to start the day.
Caffeine works by stimulating the central nervous system. This can quickly cause you to become more alert with an immediate burst in energy. When consumed in excess, caffeine can cause unpleasant side effects like anxiety, irritability, restlessness, and difficulty sleeping.
For this reason alone, most coffee and tea drinkers are concerned about balancing their caffeine intake. Sure, you want that pleasant buzz to help wake you up in the morning, but you also want to naturally come down by the end of the day so that you can get your beauty rest at night.
