Stress activators

What are the inducers of stress reactions? They consist of a large number of complex, variable external and internal events. External, psychological stressors may include socioeconomic handicaps such as demanding work environments or poor economic conditions. Psychosocial handicaps include divorce, living alone and bereavement. Other external stressors are a poor physical working situation with noise, polluted air, toxicological hazards, etc. Internal stressors might be infections or other diseases, trauma and sleep deprivation. In addition to the large number of stress factors, different personalities perceive pressure differently: what one person counts as stressful does not necessarily apply to another person.

The complexities of this field have led researchers to define 'stress' as any factor that activates the stress axes: the HPA axis and/or the central sympathetic nervous system.
