Do you know your 'sweat score'? The rise of hydration tech

Do you know your'sweat score'? One of the biggest controversies of the 2026 World Cup so far has been the hydration breaks, which - while not entirely new - are for the first time occurring twice during every match in the tournament. The breaks aren't really about hydration, some spectators say. They're just an opportunity for certain broadcasters to show more ads, they break up the natural flow of games, and are unnecessary in air conditioned stadiums. Whether or not you agree with these complaints, there's no doubt that hydration itself is an increasingly prominent point of discussion worldwide.
