For you to stay healthy, your immune system must stay strong. Drinking too much alcohol threatens the very system designed to protect you.
Even people who drink heavily on just one occasion affect their immunity.
Excess alcohol causes a change in the immune system by altering the cells and molecules in the body. This change slows your ability to ward off infections – for up to 24 hours after getting drunk.
Alcohol misuse increases the chance of contracting diseases like pneumonia and tuberculosis. Changes in liver function resulting from chronic drinking can even make the immune system turn against the body’s own tissues.
