Alcohol affects how your brain functions. It’s a central nervous system (CNS) depressant, which impairs your natural ability to perform cognitive functions like forming memories, making decisions, and regulating emotions or urges.
Jennifer Worley, a licensed marriage and family therapist from First Light Recovery, San Juan Capistrano, California, explains alcohol changes neurotransmitter levels, especially those of gamma aminobutyric acid and dopamine.
“As a result, alcohol can lower inhibitions and alter judgment, cognition, and mood,” she says. “When people consume alcohol, it can magnify underlying feelings or tendencies, making them more pronounced.”
