Disputes with a partner impair immunity.

Disputes and secrets between partners worsen not only their mental, but also their physical condition. Omissions and quarrels can lead to emotional stress and weaken the immune system. Scientists measured the level of C-reactive protein in the blood of volunteers, made them small wounds on their forearms and then watched how soon they healed in the process of communication between spouses. It was this indicator that made it possible to assess how well the immune system works.
