There are no known cures for colds or the flu, so cold and flu prevention should be your goal. A proactive approach to warding off colds and flu is apt to make your whole life healthier. The most effective way for preventing the flu is to get the flu shot. It may not be natural, but it works better than anything else. But there are other strategies you can employ as well.
#1 Wash Your Hands
Most cold and flu viruses are spread by direct contact. Someone who has the flu sneezes onto their hand, and then touches the telephone, the keyboard, a kitchen glass. The germs can live for hours — in some cases weeks — only to be picked up by the next person who touches the same object. So wash your hands often. If no sink is available, rub your hands together very hard for a minute or so. Or rub an alcohol-based hand sanitizer onto your hands.
#2 Don’t Cover Your Sneezes and Coughs With Your Hands
When you feel a sneeze or cough coming, use a tissue, then throw it away immediately. If you don’t have a tissue, cough or sneeze into the inside of your elbow.
#3 Don’t Touch Your Face
Cold and flu viruses enter your body through the eyes, nose, or mouth. Touching their faces is the major way children catch colds, and a key way they pass colds on to their parents.
#4 Drink Plenty of Fluids
Water flushes your system, washing out the poisons as it rehydrates you. A typical, healthy adult needs eight 8-ounce glasses of fluids each day.
#5 Take a Sauna
Researchers aren’t clear about the exact role saunas play in prevention, but one 1989 German study found that people who steamed twice a week got half as many colds as those who didn’t. One theory: When you take a sauna you inhale air hotter than 80 degrees, a temperature too hot for cold and flu viruses to survive.
#6 Do Aerobic Exercise Regularly
Aerobic exercise speeds up the heart to pump larger quantities of blood; makes you breathe faster to help transfer oxygen from your lungs to your blood; and makes you sweat once your body heats up. These exercises help increase the body’s natural virus-killing cells.
