It can give a momentary feeling of calm, but alcohol does not reduce stress: it chemically depresses it. When the effect wears off, the discomfort is still there… and often it comes back with more intensity.
Although it “makes you sleepy”, it fragments rest, worsens emotional regulation and increases anxiety the next day.
If you turn to alcohol every time you feel bad, the brain learns quickly: discomfort = drinking. This increases the risk of tolerance, more consumption and long-term mental health problems.
