Distilled spirits (like vodka, whisky, and gin) and most wines have at least 13% alcohol.

How to counteract alcohol-induced dehydration

Alcohol is a diuretic and therefore causes excessive urination. In this article, we describe how alcohol dehydrates the body and provide tips on how to counteract dehydration due to alcohol consumption. “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.

When the body is dehydrated, it tries to conserve water by producing less urine. However, alcohol can interfere with this process and cause the body to produce more urine than it needs to (breaking the seal). This can lead to dehydration and further electrolyte imbalances.

The most common symptoms of alcohol intolerance include skin flushing and a stuffy nose. However, more severe reactions can include red, itchy skin bumps (hives), worsening of asthma, low blood pressure, nausea, vomiting, and diarrhea. Diuretics cause the kidneys to release more water into the bladder. Alcohol dehydrates you by entering the bloodstream and breaking down the general makeup of the body. The body is made up of large amounts of water, minerals, and proteins. Consumption of alcohol affects the function of fluids throughout the body.

Whether you’re exercising or just out in the heat, sweating causes a loss of fluids and electrolytes. Unless you drink more water to replenish what you’ve lost, it can lead to dehydration. Alcohol is a diuretic because it suppresses the release of vasopressin, also known as antidiuretic hormone.

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. It can also cause muscle cramps due to an imbalance of electrolytes in the body, such as sodium, potassium, and magnesium, which are essential for proper muscle function. Dehydration can reduce muscle endurance and performance, making it more challenging to sustain physical activity for an extended period. This is because dehydration leads to a reduction in blood flow to muscles, limiting the delivery of oxygen and nutrients needed for muscle function. Dehydration can also impair cognitive function, including memory, attention, and decision-making abilities.
