'Tis the season for drinking. You're bound to enjoy champagne [1] toasts with family, wining and dining with friends, and sipping back an eggnog at your office holiday party. One drink is fine, but a recent study [2] shows that for women, consuming more than two alcoholic drinks a day can lead to heart problems. The condition is known as atrial fibrillation [3], and it's a type of rhythm disorder that causes a rapid heart rate. This can lead to difficulty breathing, fainting, fatigue, dizziness, and could even lead to a deadly stroke. Drinking more than two drinks a day increases a woman's risk for atrial fibrillation by 60 percent.

So enjoy the holidays with a mulled wine [4] or hot toddy, but don't go overboard, for your heart's sake. And if that is not reason enough to stop after one glass, check out these five reasons [5] to drink in serious moderation.
