Preventing allergies Preventing Allergies Growing up in a busy, crowded house may be good for your children. Sharing a room with siblings, having a dog underfoot and having brothers may not seem like the ideal environment for growing up, but researchers in Norway say that these types of environment may help keep children from developing allergy problems. Researchers suspect that's because children from large families are more likely to be exposed to a variety of germs at an early age, so they develop stronger immune systems.
Boys develop more serious infections, so having brothers exposes children to more diseases.
Sharing a room and sharing food at the table also increases exposure. The researchers say children who are predisposed to allergies may not receive the protective benefits from growing up in a large family. First, drink plenty of fluids. This keeps nasal secretions thin so they flow more readily and don't stay in the sinuses where they become a breeding ground for infection. Secondly, rinse your nose with a saline spray and lastly, take decongestants.
