Survive sniffle season

Remedy #1: Drink plenty of fluids.
While you can't flush a cold out of your system, experts say, drinking plenty of liquids can help. Water, juice, clear broth or warm water with lemon and honey helps loosen congestion and prevents dehydration. Hot liquids can also soothe inflamed membranes that line your nose and throat.

Beverages to avoid: alcohol, coffee and caffeinated sodas, all of which make dehydration worse.

Remedy #2: Load up on the vitamins.
Much of the scientific research on the effectiveness of vitamin supplements and herbal remedies has produced conflicting or unclear conclusions.

- Vitamin C. While Vitamin C doesn't appear to prevent colds in most people, taking large doses -- up to 5,000 milligrams -- at the first sign of a cold may reduce the severity of symptoms. And lower doses of 200 to 300 milligrams may shorten a cold's duration. So what is the optimum dose? Experts say it isn't clear, but amounts in excess of 2,000 milligrams a day may cause nausea and diarrhea.

- Echinacea. A 2005 National Center for Complementary and Alternative Medicine study in the United States found that Echinacea did little to prevent or shorten colds. But a more recent study published in the journal Lancet Infectious Diseases (September 2007) found that the herb decreased the odds of getting a cold by 58 per cent and reduced the duration by about a day and a half.

- Zinc. While the cold-fighting ability of zinc lozenges is yet to be proven, zinc nasal gel may have a positive effect, according to a comprehensive review of zinc studies by the Stanford University School of Medicine. The study was published in the journal Clinical Infectious Diseases in September 2007. For more, click here.
