8 Things that Will Dehydrate You Fast

Being sick

Whether you have the common flu or COVID-19, or of course, other diseases that can cause fever, it’s very important to stay hydrated, because when your body has a higher temperature, you need to drink more water. So, “you need to drink more fluids,” says Goodson.

In general, being sick can decrease your appetite, so you won’t eat enough or you won’t be able to get all the essential nutrients for that day, and your body will need to be hydrated. In this case, you can opt for a drink that contains electrolytes such as Gatorade or soup. “Soup is saturated with salt, which will help you retain fluid,” says Goodson.
