Headaches, excessive muscle tension, high blood pressure, rapid heartbeat, interrupted digestion, and other symptoms are often recognized as some of the more common symptoms of stress and your health.
However, having said that, there are indeed longer-term, and more serious, potential consequences from chronic stressful environments.
In part, studies undertaken at the National Institutes of Health and elsewhere, strongly suggest that stress has an effect on the immune system. Interestingly enough, the effect of such stress can actually be positive, as well as negative.
Since stress, under certain circumstances, can be a person's 'fight or flight' response to a perceived threat, it can have a positive effect. In this scenario, stress triggers the release of bodily chemicals that can actually aid in the healing infections from bites, punctures or other damage.
