Caffeine has long been considered a diuretic. For unknown reasons, this claim has been widely circulated, and some even believe that patients at risk of dehydration should not consume caffeinated beverages; In addition, coffee should not be drunk in particularly hot summers to prevent dehydration. While there seems to be some truth to this statement, it is actually wrong.

Conceptually, a diuretic is a substance that increases the level of urine produced by the body. Therefore, any large-volume beverage, including purified water, is considered a diuretic. What's more, an increased response to urination does not necessarily mean dehydration.

Drinking water will promote the body's absorption of water, and it will also promote the urination response. If a drink triggers a lot of urination, then its ability to hydrate should be weak. In addition, caffeine itself is a weak diuretic, and the body tolerates caffeine-induced urination within a few days, so it does not cause severe symptoms.

This conclusion was known almost 100 years ago. In 1928, a study of three volunteers showed that caffeine intake would trigger significant urine excretion when the body reached the level, but that caffeine intake lasting 4-5 days would trigger a tolerance response. This result suggests that daily caffeine intake does not cause dehydration.

Of course, the sample size of this study was small, but another study with 59 participants from more than a decade ago confirmed this conclusion. In any case, dehydration does have a clear correlation with physical damage. The dehydration response can lead to lethargy, which affects the function of the brain and heart.

However, while some caffeinated beverages, such as cola and energy drinks, have obvious health risks, such as high sugar content, etc. But there's really no need to worry about the caffeine.
