Caffeine is a substance found in drinks like coffee, tea, and soda that can give you energy and help you feel more awake. It is often consumed in the morning to help people start their day or in the afternoon to prevent feelings of drowsiness. However, too much caffeine can cause jitters, anxiety, and sleep problems. It is important to be aware of how much caffeine you consume and to remember that it can affect your body differently depending on your age and overall health.
