Alcohol Isn't Helping Your Immune System. It's Just Getting the Credit.

An Instagram post landed in my feed claiming that people who drink get sick less often than people who don't. It sounded just believable enough. Psychologists, stress, moderation, all the right words. And then, quietly, the disclaimer: correlation doesn't equal causation.

That disclaimer is doing a lot of work.

Who's in the "non-drinker" group?

The problem with most "drinkers are healthier" findings is the comparison group. "Non-drinkers" often includes people who stopped drinking because they were already sick, on medication, or in recovery. Compare moderate drinkers to that group and drinking looks protective. It isn't. The baseline is skewed.

Researchers have tested this. A 2016 review of 87 studies covering nearly 4 million people found that the apparent benefit of light drinking disappeared once they corrected for former drinkers and other flaws in how the studies were built. The "moderate drinkers live longer" story didn't hold up.

What alcohol does to your immune system

Alcohol disrupts immune pathways in ways that make it harder for the body to defend against infection, according to a review from the National Institute on Alcohol Abuse and Alcoholism. It also disrupts sleep, raises inflammation and can worsen anxiety. None of that is a wellness strategy.

Alcohol is getting credit for the environment

The benefits in posts like this are real. They just aren't coming from the drink. People who drink socially often have more connection, less isolation, and a moment in the day when they let their shoulders drop. Those things help your health. Alcohol just happens to be in the room when they happen.

It's the same move alcohol makes everywhere: borrow the feeling and take the credit. It's how a beer brand ends up claiming a championship, and it's why the question in If You're Not Drinking to Get Drunk, What's the Point? matters so much: what job are you actually hiring the drink to do?

Temperates Takeaway

If the benefit is lower stress, better connection and feeling more relaxed, then that's the goal. Not the alcohol. You don't need a drink to feel connected, take the edge off or exhale at the end of the day. You need better ways to get there, without the trade-offs.

Stop giving alcohol credit for benefits it didn't earn.
