Stress can weaken defenses – Study

Research from the lab of Mark Alkema, PhD, professor of neurobiology, sheds light on how the “flight-or-flight” response impairs long-term organism health. The study, conducted in the nematode worm, C. elegans, a common research model, was published in Nature.

When humans perceive a dangerous or stressful situation, the body releases stress hormones such as adrenalin. Adrenaline makes the heart beat faster, increases blood flow to the brain and muscles, and stimulates the body to make sugar to use for fuel. The rush of adrenaline triggers the “fight-or-flight” response which gives the person the ability to escape a predator or respond to a threat. Continue reading

Stress Impacts Hormones and Health in Both in Childhood and Adulthood

I have been writing about the dangers and damage of stress on the body for nearly the entire nine years of producing this blog. Check out my Page – How to Deal with Stress for more details.

Adults who report high levels of stress and who also had stressful childhoods are most likely to show hormone patterns associated with negative health outcomes, according to findings published in Psychological Science, a journal of the Association for Psychological Science.

One of the ways that our brain responds to daily stressors is by releasing a hormone called cortisol — typically, our cortisol levels peak in the morning and gradually decline throughout the day. But sometimes this system can become dysregulated, resulting in a flatter cortisol pattern that is associated with negative health outcomes. Continue reading

Exercise combats addiction – Study

As far as I am concerned when it comes to the benefits to our body and brain from exercise, the hits just keep on coming. The University at Buffalo Research Institute on Addictions reports the following good news.

Summary: Researchers report, in animal models of addiction, daily aerobic exercise alters the mesolimbic dopamine pathway in the brain.

New research by the University has identified a key mechanism in how aerobic exercise can help impact the brain in ways that may support treatment — and even prevention strategies — for addiction.

Also known as “cardio,” aerobic exercise is brisk exercise that increases heart rate, breathing and circulation of oxygen through the blood, and is associated with decreasing many negative health issues, including diabetes, heart disease and arthritis. It also is linked to numerous mental health benefits, such as reducing stress, anxiety and depression. Continue reading

Breath control helps quell errant stress response – Harvard

A hundred years ago, it seems, I dated a woman who taught yoga. While we were dating I did yoga every day. After we parted, I still practiced daily yoga for some years. While I still do yoga from time to time, one aspect I have carried into my daily life is breath control. I can honestly say that I use it to calm myself at some point every day of my life. I also employ it at night when I finally crawl under the covers. I am quick to sleep. Herewith Harvard Medical School on relaxation techiques.

The term “fight or flight” is also known as the stress response. It’s what the body does as it prepares to confront or avoid danger. When appropriately invoked, the stress response helps us rise to many challenges. But trouble starts when this response is constantly provoked by less momentous, day-to-day events, such as money woes, traffic jams, job worries, or relationship problems.

Health problems are one result. A prime example is high blood pressure, a major risk factor for heart disease. The stress response also suppresses the immune system, increasing susceptibility to colds and other illnesses. Moreover, the buildup of stress can contribute to anxiety and depression. We can’t avoid all sources of stress in our lives, nor would we want to. But we can develop healthier ways of responding to them. One way is to invoke the relaxation response, through a technique first developed in the 1970s at Harvard Medical School by cardiologist Dr. Herbert Benson. The relaxation response is a state of profound rest that can be elicited in many ways, including meditation, yoga, and progressive muscle relaxation.

Breath focus is a common feature of several techniques that evoke the relaxation response. The first step is learning to breathe deeply.
