Which statement about immune system and alcohol is true?

• A. It strengthens immune system
• B. It weakens
• C. It doubles
• D. No impact

Answer: (B)

Alcohol's effect on the immune system is to weaken it. When you drink, especially in larger amounts or over time, immune cells such as neutrophils, macrophages, and T cells don’t work as well, making it harder for the body to fight off infections. It can also disrupt the gut barrier and change how cytokines signal the immune response, which further lowers protection and can raise the risk of infections like pneumonia after drinking. While some studies explore nuanced effects with light or moderate use, the overall takeaway is that alcohol tends to impair immune defenses rather than strengthen them, so the true statement is that alcohol weakens the immune system. It does not reliably double immune strength, and there is a real impact on immune function with alcohol use.
