Some people forget to drink when hungry, which can impact the amount of fluids they consume. Without proper fluid intake, your losses can exceed your intake, which can increase the risk of dehydration. According to a small study in 11 men, consuming beer with a 5% alcohol content after exercise increased urine output significantly more than consuming a sports drink did (10). But, as Lindsey Pfau, M.S., R.D., points out, just one beer, for example, also has a lot of non-alcoholic fluids, which will help lessen the dehydrating effects of one beer. Sugary and caffeinated drinks can have diuretic effects similar to alcohol, leading to further dehydration.

• If a person is dehydrated, electrolytes move in and out of cells to maintain normal fluid levels within the body.
• You weren’t planning for a headache, nausea, and endless trips to the bathroom to interrupt this party.
• Specifically, alcohol can lower levels of potassium and magnesium, two important electrolytes.
• However, the diuretic effects of caffeine ingestion appear to vary among individuals.
• However, water might build up in other areas as our body tries to hold onto the fluids it has.

What happens if you only drink soda and no water?

“The best beverages to rehydrate with should include electrolytes like sodium and potassium, as well as calories from carbs, proteins or fats to help the fluids be absorbed into the cells,” Pfau says. Milk is also a good choice to help you rehydrate, assuming your hangover hasn’t put you off dairy. The same 2016 study from the American Journal of Clinical Nutrition found that milk was more hydrating than water, sports drinks, coffee, tea, and a handful of other common beverages [6].

Data on Excessive Alcohol Use

No matter the cause of our dehydration, it’s important for us to replenish our fluids as soon as possible. Being dehydrated can lead to some serious consequences, which we’ll investigate further.

If you’re drinking at altitude, you should probably start out with less alcohol than usual.

If you are experiencing dry mouth or skin, headaches, muscle cramps, or dark-colored urine, these are signs of dehydration.

Hydrating Drinks to Consume (Plus Dehydrating Beverages to Avoid)

When you lose too much water without properly replacing it, you become dehydrated. Dehydration can cause mild symptoms like headache, dry mouth, dizziness, and fatigue, or severe issues like damage to the brain, heart, kidneys, and even death (1). By now you know that alcohol does not have hydrating properties.

• This can lead to dehydration and further electrolyte imbalances.
• Consuming a meal containing plenty of healthy fats before drinking buffers alcohol absorption and allows more time to process and detoxify alcohol, which helps prevent dehydration.
• There are mixed opinions on whether exercise can help your body metabolize alcohol more rapidly (most likely, it can), but it’s worth a try and it’ll likely help you sober up.
• Additionally, foods with high water content, such as fruits and vegetables, can help counteract the dehydrating effects of alcohol.
• While tea tends to have less caffeine than coffee, increased tea consumption can still contribute to the total amount of caffeine a person has each day and yield dehydration.

Second, if you weigh 60 kilograms, you generate about 60 millilitres of urine each hour. And for 80 kilograms, about 80 millilitres per hour, and so on.

While drinking plenty of water is crucial to compensate for the fluid loss caused by alcohol, water alone will not hydrate you. Although beer has a high water content, it does not hydrate us. A small amount of beer will not lead to severe dehydration, but we should not drink beer to rehydrate. If we’re experiencing any of these after excessive alcohol consumption, we could have alcohol dehydration, which can result in serious health consequences.

“ADH helps your kidneys hold onto water. The less ADH, the more you urinate. The more you urinate, the more dehydrated you become.” Other lifestyle factors, such as exercise, climate, and medication use, can also impact alcohol’s dehydrating effects. In this article, we will discuss the relationship between alcohol and dehydration, the negative effects of dehydration on the body, and practical tips for staying hydrated while consuming alcohol.
