When you suffer from swine flu, your body will be taxed heavily in terms of energy, water, and nutrients. Being sick with swine flu – or any flu for that matter – often leaves your dehydrated, which makes it very hard for your body to function properly, let alone fight off an infection. Increasing your intake of water is essential if you want to rid yourself of swine flu, and while approximately 8 glasses of water are recommended on a normal, healthy basis, you should increase that to at least 10-12 glasses per day. If you are suffering from diarrhea symptoms, then drinking water becomes even more important!
