Some recent articles have cautioned that people should be careful not to drink too much water when exercising. Drinking excessive water can cause a condition known as hyponatremia, or water intoxication, which can be fatal in extreme cases. Doctors advise that people listen to their body and only drink when thirsty.

These articles are a good reminder that anything – even water – can be harmful if overconsumed.

What you don’t see in response to these articles, is activists calling for new "water taxes" or a ban on large sizes of water. That would be ridiculous. Instead, health care professionals advise people to exercise their own good judgment and drink water in moderation. What a marked change from how these same activists approach other beverages such as soft drinks.

Singling out one category of products for special taxes or bans does nothing to promote a healthy and balanced lifestyle. Instead, that energy should be redirected to help educate people about the importance of a balanced diet, where even things like cupcakes and soft drinks can be enjoyed in moderation.
