The word "stimulant" refers to anything that increases activity or excitement in the body. It is often used to describe caffeine, a substance found in coffee, tea, and energy drinks, which helps people to feel more awake and alert. Stimulants can also refer to drugs that are used to treat attention deficit hyperactivity disorder (ADHD) or to help people stay awake for long periods of time. It is important to use stimulants responsibly and under the guidance of a healthcare professional.
