10 Signs of the Flu

Flu Sign #6: Fatigue
When you have the flu, your natural immune system launches into action to try and fight it. This takes up a lot of resources and is a lot of hard work. With resources going on fighting the illness instead of to energizing other parts of the body, we can be left feeling exhausted.
Fatigue is a common symptom and is not necessarily something to be concerned about. Just make sure you get plenty of rest and give your body the fuel it needs to win the battle. It will pass once the flu has gone, leaving you feeling full of energy again.
