What you need to know: Your immune system runs at low speed when you're pregnant, which is a good thing, since it keeps your body from fighting off the baby — a foreigner to your body. The down side of this immune suppression, though, is that your body can't fight off colds or flu as well as it normally does — making you extremely vulnerable to coming down with a stuffy or runny nose, a cough, or a sore throat
1. Rest, and plenty of it
2. Water, and plenty of it
3. Lots of clear, decaffeinated liquids, such as teas and broths
4.Orange juice or other juices with vitamin C
5.Taking your prenatal vitamin, which contains vitamin C to boost your immune system and zinc to help fight off germs. And don't forget to get your vitamins and minerals the natural way — by eating food rich in nutrients. You can find vitamin C aplenty in citrus, strawberries, melon, kiwi, mango, papaya, broccoli, red cabbage, tomatoes, bell peppers, spinach, and a host of other delicious foods. Get your zinc from turkey, beef, pork, cooked oysters, yogurt, wheat germ, oatmeal, and eggs.
6. Eating fresh garlic — known to have virus-fighting compounds (if you can actually get it down), or using anti-viral spices such as cardamom, cinnamon, and cloves in your cooking
6. Humidifiers to keep the air around you moist (consider a warm mist humidifier)
7. Saltwater gargles to relieve sore throat pain (try one teaspoon of salt in eight ounces of warm water to get the fastest relief)
8. Steam inhalation or nasal lavage to relieve nasal congestion or sinus headaches (for lavage, dissolve a quarter teaspoon of salt and a tiny pinch of baking soda into eight ounces of lukewarm water, and use a nasal aspirator to irrigate — or clean — out your nasal passages)
9. Saline sprays to moisten your nasal passages (but make sure not to use the medicated sprays)
