Like life, stress happens; there is good stress and there is bad stress. Good stress is experienced when planning for a happy event like a wedding or the birth a baby. Bad stress is experienced during difficult times such as financial hardship or illness. Stress is a normal reaction to life’s demands. It exerts psychological and physical strain that, if not handled well, can cause cardiovascular and digestive disorders, sleep and memory problems, as well as depression and cancer.
Stress sets into motion the body’s alarm system. It triggers the brain to produce “flight or fight” hormones which start a cascade of events that affect the whole body. The alarm is sounded first in the hypothalamus: a small cone-shaped gland in the brain. The hypothalamus sends an emergency message to the adrenal glands (located over each kidney) instructing them to release the powerful hormones adrenaline and cortisol. Adrenaline immediately increases heart rate and blood pressure to stimulate the production of energy while Cortisol increases blood sugar (vital for energy and cellular function) and enhances the brain’s ability to use it. Cortisol also stimulates the production of essential chemicals and other substances needed for tissue repair. But, in its efforts to respond to a threat it inadvertently disrupts the immune, digestive, and reproductive systems, as well as the growth process.
The alarm system is programmed to turn-off when the threat is gone - returning the body to normal function. If threat and stress remain constant, the alarm continues to sound and the person is put at greater risk for physical and emotional ill health.
Each person’s stress response is unique because it is linked to heredity and experience. Genes contribute to how quickly and forcefully the alarm system is activated, while experience is the learned response to stress. And, although this is true, a person can learn healthier ways to respond. One way is by identifying and sorting through stressors and then letting go of those that cannot be controlled. Engaging in regular exercise, practicing daily relaxation techniques, and getting enough sleep also contribute to a healthy stress response. Developing positive relationships, attending a support group, and seeking professional counseling when needed are important, too.
Employing positive coping skills that worked in the past can help you in the present. Discover what works and practice using them daily…for the reward of learning how to respond to stress healthfully is peace of mind and a happier outlook on life.
