I liken it to valuable real estate that we need to preserve and maintain over our lifetime. Unfortunately, aging and suboptimal lifestyle decisions can destroy this precious real estate.

These hormones released from the adrenal gland help us acutely to survive the stressor at hand. The stress hormones help focus our attention, heighten our senses, increase our heart rate, increase our blood pressure, and rapidly mobilize energy for fuel. The stress response arms us for action.
The activation of the stress response gives us what our body needs to utilize immediately, whether we choose to “fight” or “run like hell”. Our chances of surviving any stressor are contingent on the activation of this acute stress response. After the stressful event, our body is able to recalibrate stress hormone levels and allow us to return to our baseline. The stress response works extremely rapidly to activate our nervous system, immune system, cardiovascular system and metabolism. After the stressor, when we relax, our body is able to activate the relaxation response and take us off “high-alert ” status. Continue reading “Aging Forces: Chronic Stress”
