If you have allergies, you may want to put down that bottle of antihistamines and let your sneezes do their job. A new study from Cornell University suggests that allergies may protect against certain types of cancer by expelling carcinogenic particles from the body.
Allergies appear to protect against cancers that occur in organs that come in contact with environmental particles – the mouth, throat, colon, rectum, skin, cervix, pancreas, and glial brain cells.
While allergies can also protect the lungs against cancer, asthma actually increases the risk of lung cancer because asthma often blocks the expulsion of mucus.
If allergic reactions offer protection against cancer, then excessive use of antihistamines is probably not a good idea – because antihistamines essentially turn off the cancer protection.
The best route to allergy relief is to avoid the allergens in your environment. First, you need to know what causes your allergies. Common allergens include dust mites, mold, pollen, and pet dander. Then you can control your environment to keep it free of allergens. Dust mite covers, for example, will keep dust mites out of your mattress and pillows. A dehumidifier will prevent the growth of mold. HEPA air cleaners and vacuum cleaners also help to keep your home free of microscopic allergens.
