Stress: Do not forget the hugs

The caresses of the virtues would have health benefits, according to a U.S. study. They lead to a reduction of stress and blood pressure. American psychologists have conducted a clinical trial with 34 couples whose partners were in good health between 20 and 39 years. For four weeks, 20 engaged couples, three weekly sessions of 30 minutes, exercises, thoughtful touch. The other 14 couples (control group) were simply instructed to take notes about the demonstrations of affection that is lavished, without making changes to their behavior. The researchers measured participants' blood pressure and the rate of two hormones and an enzyme linked to stress before, during and after the test. According to the results, levels of oxytocin and salivary alpha-amylase were higher among couples practicing touch participants than among the control group. Oxytocin, also known as the hormone of love, and alpha-amylase, a digestive enzyme, the two substances are associated with stress management. Researchers have observed no effect on blood levels of cortisol, a hormone that is often used as an indicator of stress. The study also reported a slight reduction in blood pressure, most evident in men than in their partner. Before the test, the tension of men was higher than that of their partner. Participants of the "caress" should apply a technique to increase their awareness of the psychological mood of their partner and their physiological state, by affecting the neck, shoulders and hands. As a first step, the partners were sitting practice for cuddles, and they continued lying on their backs, side by side, letting himself be gradually drawn into a gentle rocking each other.
