Though stress neuroscience in recent years has given researchers like me new ways to measure and understand stress, you may have noticed that in your doctor’s office, the management of stress isn’t typically part of your treatment plan.

Most doctors don’t assess the contribution of stress to a patient’s common chronic diseases such as diabetes, heart disease and obesity, partly because stress is complicated to measure and partly because it is difficult to treat. In general, doctors don’t treat what they can’t measure.

Stress neuroscience and epidemiology have also taught researchers recently that the chances of developing serious mental and physical illnesses in midlife rise dramatically when people are exposed to trauma or adverse events, especially during vulnerable periods such as childhood.

Over the past 40 years in the U.S., the alarming rise in rates of diabetes, obesity, depression, PTSD, suicide and addictions points to one contributing factor that these different illnesses share: toxic stress.

Toxic stress increases the risk for the onset, progression, complications or early death from these illnesses.

Because the definition of toxic stress varies from one person to another, it’s hard to know how many people struggle with it. One starting point is the fact that about 16% of adults report having been exposed to four or more adverse events in childhood. This is the threshold for higher risk for illnesses in adulthood.

Research dating back to before the COVID-19 pandemic also shows that about 19% of adults in the U.S. have four or more chronic illnesses. If you have even one chronic illness, you can imagine how stressful four must be.

And about 12% of the U.S. population lives in poverty, the epitome of a life in which demands exceed resources every day. For instance, if a person doesn’t know how they will get to work each day, or doesn’t have a way to fix a leaking water pipe or resolve a conflict with their partner, their stress response system can never rest. One or any combination of threats may keep them on high alert or shut them down in a way that prevents them from trying to cope at all.

Add to these overlapping groups all those who struggle with harassing relationships, homelessness, captivity, severe loneliness, living in high-crime neighborhoods or working in or around noise or air pollution. It seems conservative to estimate that about 20% of people in the U.S. live with the effects of toxic stress.

The first step to managing stress is to recognize it and talk to your primary care clinician about it. The clinician may do an assessment involving a self-reported measure of stress.

The next step is treatment. Research shows that it is possible to retrain a dysregulated stress response system. This approach, called “lifestyle medicine,” focuses on improving health outcomes through changing high-risk health behaviors and adopting daily habits that help the stress response system self-regulate.

Adopting these lifestyle changes is not quick or easy, but it works.

The National Diabetes Prevention Program, the Ornish “UnDo” heart disease program and the U.S. Department of Veterans Affairs PTSD program, for example, all achieve a slowing or reversal of stress-related chronic conditions through weekly support groups and guided daily practice over six to nine months. These programs help teach people how to practice personal regimens of stress management, diet and exercise in ways that build and sustain their new habits.

There is now strong evidence that it is possible to treat toxic stress in ways that improve health outcomes for people with stress-related conditions. The next steps include finding ways to expand the recognition of toxic stress and, for those affected, to expand access to these new and effective approaches to treatment.
