There is no known cure for the common cold or influenza, although researchers keep looking for one. Most colds will last 7-9 days and most bouts of the flu 2-3 days with or without treatment, but there are things you can do to feel better while it lasts.

General tips

• Get plenty of rest -- as much as 12 hours or more a night.

• Drink liquids -- to keep mucus thin and easy to clear.

• Over the counter drugs offer relief for nasal congestion, fever, muscle aches and sore throat. Never give aspirin to a child younger than 16 without a doctor's advice, and don't give cold medications to children less than 6 years old.

Congestion

• Decongestants are alright for temporary relief of a stuffy nose, but should not be used for more than five days since the body may fight back by producing even more mucus. Consult a doctor before taking a decongestant containing pseudoephedrine if you have diabetes or heart, blood pressure, prostate or thyroid problems.

Fever

• Over-the counter analgesics such as aspirin, ibuprofen and acetaminophen may offer relief, but may also prevent your body from generating the heat it needs to fight a cold or flu virus. Consult your doctor if your fever lasts for more than three days or your fever is greater than 103° F.

Cough

• Over-the-counter cough suppressants offer temporary relief, but suppressing a cough is not always a good idea since it is the body's way of clearing breathing passages.

• Drink fluids.

• Sleeping with your head elevated six to eight inches above your feet may reduce nighttime coughing.

Sore throat

• Get plenty of rest.

• Gargle with warm salt water - mix 1/2 teaspoon of salt in a glass of warm water. Warm water gargles made with chamomile tea, fresh lemon or apple cider vinegar may also offer relief.

• Soothe the throat with cough drops, hard candy or sugarless gum. These stimulate secretion of saliva, which bathes and cleanses the throat.

• Rest your voice -- If your sore throat involves an inflamed larynx, talking a lot may lead to more irritation and temporary loss of your voice.

• Humidify the air -- Adding moisture to the air prevents irritation caused by dry mucous membranes. Saline nasal sprays also help.

• Avoid air pollutants -- Avoid smoking and smoke-filled rooms, and fumes from household cleaners or paint.

Note: See a doctor if you were exposed to strep or have any of these symptoms: fever, nausea, diarrhea, vomiting, swollen neck glands, difficulty breathing or swallowing, tonsils with pus, or severe pain that doesn't improve in a few days.
