COVID-19 taught most people that the line between tolerable and toxic stress – defined as persistent demands that lead to disease – varies widely. But some people will age faster and die younger from toxic stressors than others.

So how much stress is too much, and what can you do about it?

I’m a psychiatrist specializing in psychosomatic medicine, which is the study and treatment of people who have physical and mental illnesses. My research is focused on people who have psychological conditions and medical illnesses as well as those whose stress exacerbates their health issues.

I’ve spent my career studying mind-body questions and training physicians to treat mental illness in primary care settings. My forthcoming book is titled “Toxic Stress: How Stress is Killing Us and What We Can Do About It.”
