Anger is an integral part of the body’s “fight, flight, or freeze” system, which helps protect us from threats or danger.
However, high levels of unresolved anger may have a negative impact on health. According to the American Psychological Association, anger has links with inflammation in older adults. This could lead to chronic diseases.
Research from 2015 suggests that the overall lifetime prevalence of intense, inappropriate, or poorly controlled anger in the general population in the United States is 7.8%. Anger seems to affect more men than women, and it also seems more prevalent among younger adults.
