1. Drink plenty of liquids. Water, juice, clear broth or warm lemon water with honey helps loosen congestion and prevents dehydration.

  2. Avoid alcohol, coffee and caffeinated sodas, which make dehydration worse.

  3. A saltwater gargle - 1/2 teaspoon salt in a glass of warm water - can temporarily relieve a sore or scratchy throat.

  4. Get plenty of rest. If you are tired, your body's resistance decreases, making you more susceptible to common cold.

  5. Have a healthy diet as it helps strengthen your immune system against the virus.
