Stimulants
Stimulants are substances that increase activity in the central nervous system, leading to enhanced alertness, focus, and energy. They can be found naturally, like caffeine in coffee, or synthetically, like those used to treat attention disorders. While they can improve concentration and mood, overuse can lead to negative effects such as anxiety, insomnia, and heart problems. Common stimulants include caffeine, nicotine, and prescription medications like amphetamines. It's important to use stimulants responsibly, as they can be addictive and may have harmful effects on health when misused.
