* Drink a lot of water. And tea, and juice, and clear broth. Fluids help your body heal from a cold by loosening congestion and preventing dehydration. Water, juice, clear broth, or warm lemon water with honey are the best fluids to rely on; alcohol, coffee, and caffeinated sodas only make dehydration worse.
* Go to bed. Rather than getting in the car and heading to the drugstore, get into bed and go to sleep. While you sleep, your body recharges your immune system, which is what fights off a cold. Studies show that people who get eight or more hours of sleep increase their resistance to cold viruses — and get better faster if they do catch a cold.
* Cheer up with chicken soup. Recent studies that tested the effectiveness of chicken soup discovered that it does seem to relieve cold and flu symptoms. Scientists believe chicken soup acts as an anti-inflammatory by inhibiting the movement of neutrophils, the cells of the immune system that mount the body’s inflammatory response. Hot chicken soup also temporarily speeds up the movement of mucus through the nose, helping relieve congestion and limiting the amount of time viruses are in contact with the lining of the nasal passages.
