Brace yourselves: The holidays are here. As you scramble to wrap all those last-minute gifts and prep yourself for a full day surrounded by your entire extended family tomorrow, go ahead and enjoy a nice glass of red wine-science says it will lower your stress levels.

We've known about the benefits of red wine, particularly of the compound resveratrol, for a while-it can lead to glowy skin, prevent cavities, and has even been tied to a decreased risk of heart disease, stroke, dementia, and other conditions. But we all know, too, that a glass of merlot can be the perfect antidote to a brutal day at the office-even if science hadn't figured out why yet. Now, a new study published in the journal Nature backs us up: Researchers found that a small dose of resveratrol can help your body better deal with stress.

Here's how it works: Reservatrol (which is also found in grapes and cacao beans) stimulates a specific stress-response protein, PARP-1, which then activates a number of genes that repair DNA, suppress tumor genes, and promote longevity genes. "Based on these results, it is conceivable that moderate consumption of a couple glasses of red wine (rich in resveratrol) would give a person enough resveratrol to evoke a protective effect via this pathway," lead author Mathew Sajish, a senior research associate in the Schimmel laboratory, said in a press release. Basically, it's proof that your glass (or two) of vino can help you stress less and live longer.
