Does having allergy make us more sensitive health-wise, helping to prevent symptomless conditions like hypertension? (This study does not prove the causality. There’s nothing in the datasets that categorically determines “sensitive health-wise.” But the question is an interesting one.)

• Hypertension is the top cause for top killers like cardiovascular disease, stroke, and dementia.

• Preventing hypertension requires active, consistent care on multiple fronts.

• But hypertension rarely shows any symptoms. It does not annoy us enough on a daily basis to prompt more active care (see “References” page).

• Unlike hypertension, allergy is a constant annoyance. One has to constantly be on the lookout for various allergy triggers.

• Such alertness may make us more sensitive to all things health. And as we become more sensitive health-wise, we may more actively lead a healthier life on multiple fronts, a necessity to prevent hypertension.

• The graphs show that far fewer of those with allergy have hypertension than do those without allergy.

• As seen below, those with allergy also enjoy lower body mass index.

• And far more of those with allergy are under “Self-care intervention” than are those without allergy.
