How chronic stress is harming our DNA. Elissa Epel is studying how personality, stress processes and environment affect our DNA â and how we might lessen damaging effects. Money problems, a heavy work load, caregiving â such increasingly common pressures have helped make stress a part of modern American life.
But through scientific research, we know that our risk actually depends on a combination of our genes, our environment and aspects of our lives, many of which we can control. Cancer is caused by damage to our DNA, the chemical instructions that tell our cells what to do. Things in our environment, such as UV rays, or our lifestyle, such as the cancer-causing chemicals in tobacco, can damage our DNA. This damage builds up over time.
