Does Alcohol Really Cause Dehydration? Alcohol & Dehydration


“Essentially, when you’re dehydrated, you’ll feel alcohol’s effects sooner and for longer,” Pfau says. A vodka with soda is likely more hydrating than just a shot of vodka because you’re consuming more fluids from the soda. According to the CDC, drinking alcohol in moderation is safe for most people. A moderate amount equates to one glass of alcohol or less per day for females and two glasses of alcohol or less per day for males. In this article, we describe how alcohol dehydrates the body and provide tips on how to counteract dehydration due to alcohol consumption. Having a few drinks can be fun, but feeling dehydrated or hungover is not.

Read on to see what experts say about alcohol and hydration. When drinking alcohol, especially in hot weather, avoiding dehydration is critical. Alcohol decreases the amount of ADH your body produces, making it harder to retain enough fluids. The higher the alcohol content, the greater this effect will be. Fortunately, researchers have discovered these effects are not sustained over multiple drinks. Alcohol will do everything in its power to steer you toward dehydration.

What Is a Hangover?

The subjects still get the initial spike in urine flow after the first drink, but then urine flow dies down. And while the non-alcoholic fluids in beer, wine, and liquor are inherently hydrating, they’re not necessarily hydrating enough to offset the effects of alcohol-induced dehydration. Alcoholic beverages contain ingredients called congeners, which give many types of alcoholic beverages their flavor and can contribute to hangovers.

It’s also a good idea to limit your alcohol intake if you are engaging in activities that can cause you to sweat or lose fluids through other means, such as exercising or being in a hot environment. If you’ve ever celebrated after work, gone out for a happy hour, or any of life’s special moments with a few alcoholic drinks, you know how it can impact every aspect of you the next day. Symptoms like a pounding headache, sensitivity to bright lights, nausea, and extreme thirst can be linked to fluid and electrolyte imbalances made worse by alcohol consumption. These symptoms are caused by the way alcohol dehydrates you.

What Are the Immediate and Long-Term Health Benefits After You Stop Drinking Alcohol?

When dehydration is detected, a message is relayed and ADH is released. Alcohol convinces the pituitary gland that ADH shouldn’t be introduced into the situation, despite the alcoholic drink itself being made up largely of water. Dehydration is a condition that develops when your body loses water or water and electrolytes.

Put Your Health First

Dehydration can increase the risk of heat stroke, especially when combined with exposure to hot and humid environments, such as in a crowded bar or nightclub. Ultimately, the only surefire remedy for a hangover is to avoid getting one by drinking in moderation or choosing not to drink. During a hangover, a person’s attention, decision-making, and muscle coordination can all be impaired. Also, the ability to perform important tasks, such as driving, operating machinery, or caring for others can be negatively affected.

Which alcohol does not dehydrate you?

That makes beer the clear contender as the least dehydrating, with a big caveat. As important as alcohol content may be, even more important is how much you drink in a given sitting. Drink too many beers too quickly, and you'll end up as dehydrated as you would taking a shot at the bar.

Dehydration doesn’t cause a hangover, but hangovers can lead to dehydration. Hangover symptoms include sweating and vomiting, which increase the risk of developing dehydration. Consuming foods with high water content, such as fruits and vegetables, can help counteract the dehydrating effects of alcohol. But if you insist on having a drink or two, there are things you can do to mitigate the dehydrating effects of alcohol.
