[Biomedical aspects of health preservation strategy: role of catecholaminergic neuronal populations].

Lifestyle, environmental factors, genetics, and medical care are the main factors that determine the health status of man. Of particular attention are biological mechanisms ensuring the body's adaptation to constantly changing environmental conditions. The noradrenergic neuronal populations, the sympathetic nervous system in particular, modulate metabolic processes and supports a variety of activities, making them relevant to changing living conditions. There is a clear correlation between the life span and the number of sympathetic nerve cells functioning during postnatal ontogenesis. The exposures that reduce the activity of peripheral and central noradrenergic neurons and slow down aging processes in them loosen the relationships between the inner and outer world to prevent hyperactivity and to prolong life.
