Should we drink a lot of water? Experts are surprised: You risk hyponatremia

Although it may seem like an obvious answer, drinking too much water during a heat wave can be harmful.

"If you drink too much, you remove important minerals from your body," says Chloe Brimicombe from the Royal Meteorological Society in Britain.

When you drink too much, your kidneys can't get rid of the excess and the sodium content in your blood becomes diluted – this is called hyponatremia and can be life-threatening.

Drinking too much water can also hinder the kidneys' ability to excrete excess fluid.

Symptoms of hyponatremia include confusion, irritability, headache, drowsiness, and a swollen abdomen, among others.
