Some steps to prevent Cold and Flu  !!!  

1- Some studies have shown that eating a daily cup of low-fat yogurt can reduce your susceptibility to colds by 25 percent. Researchers think the beneficial bacteria in yogurt may stimulate production of immune system substances that fight disease.

2- Researchers aren't clear about the exact role saunas play in prevention, but one 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.

3- 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.

4- "Phyto" means plants, and the natural chemicals in plants give the vitamins in food a supercharged boost. So put away the vitamin pill, and eat dark green, red, and yellow vegetables and fruits.

5-Most cold and flu viruses are spread by direct contact. Someone who has the flu sneezes onto their hand, and then touches something. The germs can live for hours -- only to be picked up by the next person who touches the object. Wash your hands often. No sink? Rub your hands together very hard for a minute or so. That also helps break up cold germs. 

6-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. How can you tell if you're getting enough liquid? If the color of your urine runs close to clear, you're getting enough.

7- A regular dose of fresh air is important, especially in cold weather when central heating dries you out and makes your body more vulnerable to cold and flu viruses. Also, during cold weather more people stay indoors, which means more germs are circulating in crowded, dry rooms.

8- 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.

9- Heavy alcohol use destroys the liver, the body's primary filtering system, which means that germs of all kinds won't leave your body as fast. The result is, heavier drinkers are more prone to initial infections as well as secondary complications. Alcohol also dehydrates the body -- it actually takes more fluids from your system than it puts in.

10- Statistics show that heavy smokers get more severe colds and more frequent ones. Even being around smoke profoundly zaps the immune system. Smoke dries out your nasal passages and paralyzes cilia. These are the delicate hairs that line the mucous membranes in your nose and sweep cold and flu viruses out of the nasal passages.

11- If you can teach yourself to relax, you can activate your immune system on demand. There's evidence that when you put your relaxation skills into action, your interleukins -- leaders in the immune system response against cold and flu viruses -- increase in the bloodstream. Train yourself to picture an image you find pleasant or calming. Do this 30 minutes a day for several months.
