There are two types of stress men deal with. Emotional and physical, but today the modern man deals mostly with emotional stresses instead of physical ones, though his body cannot rationalize the difference.
When it comes to emotional stress the body is sometimes flooded with naturally occurring chemicals in the body. Three stress hormones are involved in the flight or fight syndrome: cortisol, epinephrine, and oxytocin. Cortisol and epinephrine lower immunities and raise blood pressure. Oxytocin softens the reaction of cortisol and epinephrine by relaxing the emotions. Men release less oxytocin than women, and therefore have a stronger reaction from both cortisol and epinephrine. So Are Men More Stressed Than Women?
