Drink Alcohol in Moderation

Drinking high amounts of alcohol is associated with a range of negative health effects, including lowered immune function. When you drink high amounts of alcohol, your body is too busy trying to detoxify your system to bother with normal immune system function.

According to a review published in the journal Alcohol Research in 2015, high levels of alcohol consumption can weaken your body’s ability to fight infection and slow down your recovery time. As a result, people who drink high amounts of alcohol face a greater likelihood of pneumonia, acute respiratory distress syndrome, alcoholic liver disease, and certain cancers, according to the same review.

If you don’t already drink, don’t start. If you drink occasionally, limit your alcohol consumption to one drink (equivalent to a 4-ounce glass of wine) per day if you’re a woman, and two drinks per day if you’re a man, as recommended by the NIH.
