Why is alcohol classified as a depressant?

Alcohol is classified as a depressant because it affects the central nervous system in a way that slows down brain activity. This leads to a range of effects, including lowered heart rate and respiratory function, as well as a decrease in overall mental and physical activity. As a depressant, alcohol can impair judgment and coordination, resulting in the feelings of relaxation and sedation that users often experience.

The other options highlight effects associated with stimulants or promote increased mental activity, which are not characteristics of depressants like alcohol. By understanding alcohol's core classification and its effects on the body, individuals can be better equipped to make informed decisions regarding alcohol consumption and its potential impacts.
