Regular Sexual Activity Is Helpful

In a study of college students, those who had sex once or twice per week had the highest levels of immunoglobulin A (IgA) in their saliva. IgA is an immune molecule that helps protect us against illnesses like the common cold. Students who had sex once or twice per week had more salivary IgA than students who were not sexually active, infrequently sexually active (less than once a week), or who were very sexually active (three or more times per week). Enjoying sex up to a couple of times per week seems to be the sweet spot for promoting optimal IgA levels
