**8. Summary**

Environmental stressors such as ambient threshold changes in light, heat, noise atmospheric oxygen, and chemical phenomena have a great impact on the autonomic nervous system causing impairment in general stress markers. Environmental stressors orchestrated an increase in systolic blood pressure, diastolic blood pressure, mean arterial blood pressure and disrupted baroreflex sensitivity in both males and females. Derangement in body temperature and blood glucose and suppression of melatonin were also consequences of environmental stressors in both human beings and animals. Future studies will examine in detail the molecular mechanisms that underlie environmental stressor-induced changes in general stress markers.
