Does drinking coffee in hot weather cause dehydration?

On hot days, many people choose a cup of iced coffee to stay awake and cool. However, drinking coffee in hot weather also requires attention.

Coffee contains caffeine, a mild diuretic that causes the body to excrete more water through the kidneys. This leads many people to worry that drinking coffee in hot weather will cause them to become dehydrated more quickly, according to the health website Verywell Health .

However, according to Rob van Dam, a nutritionist at George Washington University (USA), moderate coffee consumption does not cause dehydration in healthy adults. The water content in coffee can partially offset the diuretic effect of caffeine.

Who shouldn't drink coffee in hot weather?

This problem often occurs in people who are not used to drinking coffee or who do not regularly consume caffeinated beverages.

At that time, the body has not yet adapted and is easily affected by the diuretic effect of caffeine. These people should limit their consumption of coffee or energy drinks on hot days to avoid excessive dehydration.

How to drink coffee while staying hydrated.

To enjoy coffee while staying hydrated, you should drink plain water in between. For example, for every 350ml cup of coffee, you should drink 1-2 glasses of plain water. This helps prevent dehydration, even though you're still drinking coffee as usual.

Natalie Newell, a nutritionist in the US, says that everyone reacts differently to caffeine, but on average, adults should not consume more than 400 mg of caffeine per day.

An espresso contains approximately 64 mg of caffeine, while a large cup of coffee contains around 90-100 mg.

If you feel parched, dizzy, tired, or have dry skin, you may be dehydrated. In that case, you should reduce your coffee intake and drink more water.
