Alcohol is a chemical substance found in beverages like beer, wine, and spirits that affects both the mind and body. When consumed, it acts as a depressant on the central nervous system, slowing brain function and altering mood, behavior, and judgment. Chronic or excessive use of alcohol can lead to physical dependence, mental health challenges, and significant long-term health risks, including liver disease, cardiovascular issues, weakened immune function, and neurological impairment. Understanding alcohol’s effects and potential risks is a crucial step in making informed choices for a healthier lifestyle.
