During adolescence, the lymphoid system, which is responsible for producing antibodies to fight off infections, shrinks. This can result in a lessening susceptibility toward respiratory infections. Greater exposure to germs from increased social activity may actually increase susceptibility to infections, while the growth spurt and increase in sex hormones are not directly related to respiratory infections.
