When the person tests strong negative feeling, - anger, fury, rage is influences not only its mutual relations with associates. The organism also is exposed to strong enough influence.
Influence of such strong emotions goes, first of all, on frequency of reductions of a cardiac muscle, arterial pressure. Development by an organism of a hormone of Testosteron-Depotum is enlarged, but level of a hormone of a hydrocortisone decreases. Strong negative emotion makes radical changes in vegetative nervous system which, in turn, supervises a condition of heart and vessels. The endocrine system of an organism is affected also.

About the changes bound to strong negative emotions, the research group of university of Valencia (Spain) declares. The author of research, Nieves Herrero, explains, that influence of emotions goes first of all on a brain. The experiments spent with participation of 30 men-volunteers, have shown approximate sequence of this influence. At first, as scientists have noted, there are changes in frontal and temporal shares of a brain. Pulse further becomes frequent, arterial pressure raises.

Results of experiments have been published in magazine "Hormones and behaviour». Data of scientists convincingly prove, that the anger causes radical changes in a sincere condition of subjects, and also in its psychobiological parametres.
