Did you know?
Frequent loving intercourse may be
one of your strongest natural defenses
against colds and flu.
Studies in psychoneuroimmunology show that regular sexual activity increases levels of Immunoglobulin A (IgA) — an antibody that plays a key role in immune defense against respiratory infections. At the same time, intimacy lowers cortisol, the stress hormone that weakens immunity when chronically elevated.
It’s not just pleasure.
It’s biology.
