Answer 1

Stimulants typically cause **increased heart rate**. They activate the central nervous system, leading to heightened alertness and physical activity, which often results in an elevation of heart rate (tachycardia). Examples of stimulants include caffeine, amphetamines, and certain medications prescribed for ADHD. While individual responses may vary, the general effect of stimulants is to increase heart rate rather than decrease it.
