Question

When do I need to drink even more water than normal?

Answer 1

You need to drink enough water to replace what you lose daily through urination, sweating, even exhaling. And you need more water when:

• the weather is warm or hot
• you do hard physical activity, such as exercise or working in the yard
• you're ill, especially if you have a fever, are vomiting, have diarrhea or cough a lot
