Behavioral changes resulting from trauma. People who are suffering from traumatic memories may try to escape them by participating in risky behaviors such as drinking, smoking, drug use, or even overeating for comfort. "Those can all be used as a coping mechanism, a way of dealing with emotional dysregulation that occurs when someone has been traumatized," says Roberts. These habits, in turn, lead to health problems.

Physical effects related to trauma. The problem goes beyond unhealthy habits. Experts believe that there is actually a direct biological effect that occurs when your body undergoes extreme stress. When you experience something anxiety-provoking, your stress response activates. Your body produces more adrenaline, your heart races, and your body primes itself to react, says Roberts. Someone who has experienced trauma may have stronger surges of adrenaline and experience them more often than someone who has not had the same history. This causes wear and tear on the body — just as it would in a car where the engine was constantly revving and racing, she says. Stress responses have also been demonstrated in people who have experienced discrimination throughout their lives. "It ages your system faster," says Roberts.

Chronic stress can increase inflammation in the body, and inflammation has been associated with a broad range of illness, including cardiovascular disease and autoimmune diseases, says Roberts. Early trauma disrupts the inflammatory system. This can lead to long-term aberrations in this system and chronic health problems triggered by constant inflammation. Typically, the more trauma you've experienced, the worse your health is.
