Why is drinking fluids important when you are sick?
When you drink a glass of water during a cold, your immune system uses it to cool down fevers, to carry away toxins and waste, to thin mucus so that you can expel it from your system, and to carry away germs that could cause a future illness. Without ample hydration, your body is powerless to fight a cold, so a smart cold care regimen makes sure that you stay fully hydrated for the duration of your illness. Your immune system will only be able to function at peak efficiency if you keep it lubricated with water, so pour yourself a glass of water and drink up!
