People who drink approximately 150 ml (5 oz) of red wine a day moderately decrease their risk compared to non-drinkers (16, 17). This phrase refers to the observation that the French have low rates of heart disease, despite consuming a lot of saturated fat and cholesterol (2). A small amount of caffeine may not be an issue for most people, though increasing caffeinated beverages may contribute to overall caffeine intake. The body may tolerate a moderate intake of beer without experiencing dehydration. A vodka with soda is likely more hydrating than just a shot of vodka because you’re consuming more fluids from the soda. For reference, a standard drink—12 ounces of beer, 5 ounces of wine, 1.5 ounces of liquor—has 14 grams of alcohol, according to the National Institute on Alcohol Abuse and Alcoholism [3].

  • People may need to drink a lot of red wine to get enough resveratrol to have an effect.
  • Acidity in red wine is more common in younger wines and certain varieties.
  • Alcohol, including red wine, may interfere with many different medications, especially those that cause drowsiness.

However, study authors warn that heavy drinkers experienced the opposite effect. If you have questions about the plusses and risks of alcohol, talk with your health care professional. And research suggests that the body can’t absorb most of the resveratrol in supplements. Further, they state that 1 in 10 deaths among adults ages 20–64 had an association with excessive drinking.

Recognizing Dehydration from Wine Consumption

In research done on the effect of wine on blood sugar levels, it was found that drinking wine with a meal lowers your blood sugar level by roughly 30%. Certain types of wine may have a more dehydrating effect than others. Factors like alcohol content and sugar levels can impact hydration levels. It’s important to drink water alongside wine to stay properly hydrated. To prevent dehydration while enjoying wine, it’s important to balance your alcohol intake with adequate water consumption. Drinking a glass of water before and after having wine can help maintain hydration levels.

The ideal wine storage temperature is approximately 55 degrees F, though the exact best temperature will vary depending on the wine. Store your bottles horizontally on a rack to ensure the wine cork remains moistened by the wine. Wine is available year-round, and many varieties may be consumed at any time of year. Depending on your preferences, budget, and storing options, you may want to consider aging your wine by keeping it in a temperature-controlled area for some time.

Do some types of alcohol dehydrate you more than others?

It’s also a good idea to alternate between alcoholic beverages and water throughout the evening. While moderate wine consumption may provide some health benefits, excessive drinking has negative effects and consequences. These include deaths and injuries from accidents, along with health problems such as liver disease, some cancers, and cardiovascular diseases.

  • A 2018 study reported that red wine and grape polyphenols might improve gut microbiota, contributing to a healthy gut.
  • But when it comes down to it, the type of wine’s impact on hydration is more about the alcohol content than these other bits.
  • Alcohol is a diuretic, meaning it increases urine production and can lead to fluid loss.

That paper summarizes that research into whether stronger alcohol is linked with increased dehydration is inconclusive. About 10% of the population is at risk of an allergic reaction to wine. Many components of wine can trigger a reaction, including yeast, molds, and sulfites. Even the flavonoids, which make red wine healthy, can cause an intolerance reaction. Red wine is one of the forms of alcohol most likely to cause a reaction in people with asthma.

Reduced Vasopressin Production

Unfortunately, alcohol reduces the natural production of vasopressin in your body. Therefore, your body becomes less adept at holding on to water over time. This, in turn, could slow down the urine production of your kidneys, which means you’ll pass the wine out of your system more slowly as well. 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.

While wine is often enjoyed for its taste and relaxing effects, it can have dehydrating effects on the body. With this understanding, let’s explore the role of hydration in the body and how wine consumption can potentially disrupt this delicate balance. While the intestines absorb alcohol quickly, it is metabolised much more slowly. Although your body’s metabolic rate can convert some alcohol into nutrients or energy, it only does so at a rate of about one glass of wine per hour.

Alcohol begins to build up in your bloodstream

Links between red wine and fewer heart attacks aren’t well understood. But antioxidants in red wine may increase levels of high-density lipoprotein (HDL) cholesterol, also called the “good” cholesterol, and protect against cholesterol buildup. For many people, enjoying a glass or two of red wine each day can be part of a healthy diet.

  • 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.
  • Not staying properly hydrated while drinking wine can lead to health risks.
  • “Partly it’s the benefits of the alcohol, but red wine also contains a lot of unique antioxidants that are hard to get other places,” O’Keefe says.
  • Look out for sweet wines from Italy, like Corvina and Amarone, or even late-harvest Zinfandels from California.
  • The CDC states that an average of 1 in 6 American adults binge drink.

Higher blood sugar may also cause the body to urinate more to get rid of this excess sugar, which can influence dehydration. 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. Antioxidants are important for maintaining good health because they protect your cells from damage. The antioxidants found in wine are polyphenols, which are compounds found in plants. One polyphenol in red wine that is of interest to scientists is resveratrol, which may have benefits including protection for your brain, heart, and body. Alcohol contains more calories per gram than carbs and protein, and many alcoholic beverages — like beer, wine, and mixed drinks — may also be loaded with sugar.

Symptoms of dehydration

The scientists believe that the ethanol in wine plays a crucial role in metabolizing glucose and that the nonalcoholic ingredients may also contribute. This is not likely to cause dehydration by itself, but in conjunction with the other side effects above, it could lead to a mild dehydration effect. Because of this, you can also feel sluggish, drained, Facing Your Powerlessness in Addiction Recovery or tired even though the alcohol technically has some carbohydrates in each glass your body should be able to use for quick energy. If you’re into cooking and you pour some wine into a frying pan then the alcohol disappears almost instantaneously.
