A good indicator of efficient exercise is a good resting heart rate. This enables athletes and health buffs to meet the needs of their body with a slow heart rate. It does not take them much effort in terms of physical activity whereas those who are out of shape would exert a lot of effort to complete a task.
The statement that stress is a factor that contributes to heart disease risk is true. As a response to stress our body releases the hormone cortisol. High levels of cortisol from long-term stress can increase blood cholesterol, triglycerides, and blood pressure and these are risks for development of heart disease.
True. Stress has been recognized as a significant factor that contributes to the risk of developing heart disease.
When a person experiences stress, the body's stress response is activated, leading to the release of stress hormones such as cortisol and adrenaline. These hormones can have various effects on the cardiovascular system. They can increase heart rate, blood pressure, and blood vessel constriction, which, over time, can put a strain on the heart and blood vessels.
Prolonged exposure to stress can also lead to unhealthy coping behaviors such as overeating, smoking, excessive alcohol consumption, or physical inactivity, all of which are risk factors for heart disease.
Furthermore, chronic stress can contribute to the development and progression of other heart disease risk factors such as high blood pressure, high cholesterol levels, and diabetes. It can also negatively impact overall lifestyle habits, including sleep quality, exercise, and healthy eating patterns.
Numerous studies have established a link between chronic stress and increased risk of heart disease, including coronary artery disease, heart attacks, and strokes. Managing and reducing stress through various techniques such as relaxation exercises, regular physical activity, social support, and stress management strategies can help lower the risk of heart disease.
