Vomiting, diarrhea, fever, and heavy sweating can all increase fluid loss.

When you’re ill, replacing lost fluids becomes especially important.

Small, frequent sips may be easier to tolerate if you’re having trouble drinking normally.

If you cannot keep fluids down or have signs of significant dehydration, medical attention may be necessary.

8. You’re Simply Not Drinking Much

Sometimes the biggest clue is the simplest one.

If you realize that you’ve gone most of the day with only a cup of coffee or a small amount of water, your body may simply need more fluids.

Keeping a bottle or glass of water nearby can make it easier to remember to drink throughout the day.

How Much Water Do You Actually Need?

There’s no single amount that works for everyone.

Fluid needs vary depending on factors such as body size, activity level, climate, diet, pregnancy, illness, and medications.

Also remember that fluids don’t come only from plain water. Milk, tea, soups, fruits, vegetables, and other foods and beverages contribute to your overall fluid intake.

Instead of obsessing over one exact number, pay attention to your body’s signals and drink regularly throughout the day.
