Alcohol affects the balance of neurotransmitters in the brain, which are chemicals responsible for transmitting signals throughout the body and influencing behavior, emotions, and physical actions.
For example, alcohol enhances the effects of gamma-aminobutyric acid (GABA), which leads to sluggish movement, slurred speech, and delayed reaction times when intoxicated.
It also reduces the effects of glutamate, which regulates dopamine in the brain’s reward center, creating feelings of pleasure and warmth.
Additionally, alcohol lowers inhibitions and impairs judgment, making people more likely to take risks.
Research has shown that alcohol can worsen symptoms and mood swings in individuals with mental health conditions such as depression or bipolar disorder.
