Chronic stress linked to heart inflammation and increased stroke risk

Research from Imperial College London and the MRC Laboratory of Medical Sciences suggests that chronic stress can cause inflammation that alters the physical structure of the heart. Individuals with the highest levels of inflammation face a 43 percent increased risk of suffering a stroke or heart attack compared to those with the lowest levels.

While traditional risk factors like smoking and a sedentary lifestyle remain critical, researchers note that social factors and psychological well-being play a significant role in triggering these inflammatory responses. Genetic predisposition also influences how vulnerable an individual is to these stressors.

To manage these risks, experts emphasize the importance of lifestyle interventions such as maintaining a healthy weight, avoiding smoking, and prioritizing recovery. Effective stress management involves creating conditions for the body to heal through consistent sleep, physical activity, nutrition, and predictable daily rhythms to help regulate hormones like cortisol.
