How to get rid of a cold
Drink extra water.
Having a drippy nose or a fever causes you to lose moisture. Make sure you drink enough so that you aren't forcing your body to deal with both the cold and the physical stress of dehydration.
When you sleep, keep a cup of water, juice, clear broth, or warm lemon water near your bed. If you sleep restlessly, this will enable you to take a few swallows each time you wake and avoid dehydration throughout the night.
