Lounging around, binge-watching Netflix, and snacking a lot is all fine and good when it's cold outside. At least that's what I tell myself. Actually, though, there are some simple ways to make being a slug just a little healthier. And not one involves a workout.

Have some wine with that

You know that alcohol in moderation can protect your heart. But vino could feasibly head off a cold. In one study in the American Journal of Epidemiology that took place in Spain, people who drank the most wine were less likely to come down with a cold than those who abstained or downed beer or spirits. Red wine has the edge, possibly because of its antioxidants. Experts say that women should stick to one glass per day for the most health benefits (and fewest risks). Cheers!

Inflammation is linked to heart disease, Type 2 diabetes, and even Alzheimer's. Resist the urge to text and pick up the phone; there's nothing like good old actual conversation.
