Studies show exercising may offer protection against hay fever.
German researchers found that among the 1,700 children they followed for up to 12 years, those who were inactive at the study's start were 50 percent more likely to develop hay fever, compared with their regularly active peers.
Exactly how is unclear, but scientists say other studies have shown that moderate exercise may benefit immune system function.
If the findings are correct, hay fever protection could be one more reason for kids to be regularly active.
