Does a hot bath help eliminate alcohol?

Many believe that a hot bath helps the body dissipate heat, reduce fatigue, alleviate drunkenness, and eliminate alcohol. Is this true? (Hung, 22, Hanoi).

Answer:

Maintaining body warmth is crucial, especially during changing weather. However, many people adopt incorrect methods to stay warm and protect themselves, which can severely harm their health.

Taking a hot bath immediately after consuming alcohol to eliminate it is extremely detrimental to health. Alcohol is primarily metabolized in the liver, with only a small amount expelled through breath, urine, and sweat. Sweating does not reduce blood alcohol concentration. Alcohol already causes blood vessels to dilate; hot water further expands them. This combination can lead to dizziness, a drop in blood pressure, and fainting. At this point, the body experiences significant dehydration, increasing fatigue. After drinking, when one's mind is not fully clear, there is a risk of fainting or falling, which can cause serious injury.

Therefore, improper bathing when the body is not in optimal condition further increases the risk of stroke and high blood pressure. While healthy, young individuals generally adapt better, the risk is significantly higher for the elderly and those with pre-existing conditions such as high blood pressure, coronary artery disease, heart failure, diabetes, or a history of stroke.

Doctors advise that warming weather does not signal the end of the "dangerous season" for cardiovascular and respiratory health, especially for individuals with underlying conditions or the elderly. After consuming alcohol, it is important to keep the body warm. Avoid strenuous activities like jogging, using a sauna, or taking hot or cold baths.
