Have you ever heard that asthma rates in kids are on the rise. Surprisingly, some experts say it may have to do with our sterile lifestyle and overuse of antibiotics. Exposure to bugs puts the immune system into fighting mode-and that is the good thing. Kids with H.pylori bacterium are half as likely to have asthma as those who don't, according to recent research.

The discovery could lead to the development of a preventive treatment.Until then, replace antibacterial soap and cleaning products with normal ones. And when possible, avoid giving your child antibiotics.
