Final answer:
Stress can affect coronary heart disease by increasing blood pressure and heart rate, promoting unhealthy behaviors, and contributing to inflammation in the body.
Step-by-step explanation:
Stress can affect coronary heart disease in several ways. Firstly, stress can cause the release of stress hormones like adrenaline and cortisol, which can lead to an increase in blood pressure and heart rate. This can put a strain on the heart and over time, contribute to the development of coronary heart disease.
Secondly, stress can lead to unhealthy coping behaviors such as smoking, poor diet, lack of exercise, and excessive alcohol consumption. These behaviors are known risk factors for coronary heart disease.
Lastly, chronic stress can also impact the immune system and promote inflammation in the body, which is linked to the development and progression of coronary heart disease.
