Despite the potential dangers, myths about drinking persist, which—for some—can prove fatal. Scientific studies supported by the National Institute on Alcohol Abuse and Alcoholism provide important information that challenges these widespread, yet incorrect, beliefs about how quickly alcohol affects the body and how long the effects of drinking last.

Intoxication and your reaction time is slowed. Plus, the sedative effects of alcohol increase your risk of nodding off or losing attention behind the wheel.

Myth: The warm feeling you get from drinking alcohol insulates you from the cold of winter. When you’re drinking, there’s no need to wear a coat when it’s cold outside.

Fact: Alcohol widens the tiny blood vessels right under the skin, so they quickly fill with warm blood. This makes you feel warm or hot, and can cause your skin to flush and perspire. But your body temperature is actually dropping, because while alcohol is pulling warmth from your body’s core to the skin surface, it is also depressing the area of your brain that controls temperature regulation. In cold environments, this can lead to hypothermia. So, wear a coat when it’s cold outside, particularly if you are drinking alcohol.

Happy New Year!
