Should You Drink Tea During a Heatwave?

When temperatures climb into the mid-30s and the city feels like an oven, many people instinctively reach for ice-cold drinks. Yet in many hot parts of the world, people do exactly the opposite. They drink hot tea.

It sounds strange, but there is some science behind it. A warm drink can make you sweat a little more. If that sweat is able to evaporate from your skin, your body cools itself more efficiently. This is why hot tea remains popular in countries where summer temperatures regularly exceed 40°C.

That does not mean tea is a miracle solution. If you are already dehydrated or spending hours in direct sunlight, water should still be your first priority. Herbal teas and regular black or green tea can contribute to your daily fluid intake, but they should complement, not replace, plenty of water.

During the historic June 2026 heatwave in Amsterdam, staying hydrated became more important than ever. The city experienced unprecedented temperatures, and many buildings, trams, and homes struggled to stay cool. If you are visiting the Dutch capital, it is worth reading this detailed guide about the historic Code Red heatwave in Amsterdam to understand what to expect and how to prepare.

If you enjoy tea, there is no need to stop drinking it because of the heat. Just listen to your body. Drink it warm rather than boiling hot, combine it with plenty of water, and avoid excessive caffeine if it makes you feel dehydrated.

In the end, the best drink during a heatwave is the one that helps you stay comfortably hydrated throughout the day.
