Alcohol intoxication commonly affects natural fears by

Explanation:
Alcohol lowers natural fears by dampening brain areas that generate anxiety and fear. It enhances inhibitory signaling in the brain (through GABA) and reduces excitatory signaling (like glutamate), which quiets the activity of fear-related circuits such as the amygdala. With these pathways less reactive, a person often feels less afraid in situations they’d normally avoid, which is why natural fears tend to decrease during intoxication. This effect is temporary and can be followed by impaired judgment and risky behavior, and it does not erase fear entirely.
