When you drink alcohol, your body treats it as a toxin and stops burning sugar or fat to metabolize it first. This triggers a heat surge that might help in hypothermia, but regular drinking is linked to Alzheimer's, cancer, heart disease, and faster aging.
If you drink alcohol, your body immediately stops burning sugar and stops burning fat because it has to burn the alcohol first because it's toxic. It's just, how do I get this crap out of here? So if you're in a hypothermic state and you drink alcohol, it's going to cause a wave of mitochondrial respiration that will heat up your tissues. This is why some people get flushed. Not the flushing that Asian people experience because they don't have liver enzymes, but people get like a burst of energy from the first drink or two. It's because you're getting a little short term mitochondrial boost. It could save you if you're freezing to death. So if you're in that situation, have a couple drinks on me. Otherwise don't do it because. Because there's just other compounds that are better for your brain, better for your social interactions and you won't wake up one day with Alzheimer's, cancer, heart disease and looking really old because you had a healthy couple of glasses of wine every night. That's what happens. If you don't believe me, go to PubMed and look at the study.
