Sleep as much as possible

The best treatment for your body when combating the flu is sleep. It's not a bad idea to watch TV while cuddled up on the couch, but you shouldn't stay up all night binge-watching your favorite Netflix series.

When you have a cold, the flu, or a fever, you may sleep a lot because your body needs rest. Your body will be better able to fight off your illness and build up its immune system if you sleep more than normal. To provide your body more time to rest, you can also nap during the day. Sleep and rest also lower your risk of developing major flu side effects like pneumonia. Don't worry if you find yourself sleeping all day when you're ill, especially at the beginning of your illness. Allow your body to get all the rest it requires, just be sure to get up from time to time to drink some water and eat some healthy food.
