It's not just about early exposure to allergens, it's also early exposure to pathogens. There's a growing body of research that constant disinfection of hands and surfaces is what really caused the allergy outbreak. Humans need to prime their immune systems with exposure to pathogenic bacteria at an early age so that it can learn to fight them and not other substances which leads to allergies. |

Careful, that's not really been proven. There's an enormously important difference between these two theories:
1. The individual human immune system needs to be calibrated by wider exposure to... actual pathogens.
2. The individual human immune system needs to be calibrated by wider exposure to... benign bacteria that we've co-evolved with. ("Old friends" [0].)
Those involve very different plan of treatment and associated risks, and there's no guarantee the riskier one will give better results.
