STRESS AND THE HEART: EFFECTS AND THE ROLE OF ADRENALINE AND CORTISOL

This scientific article provides an in-depth analysis of the complex relationship between stress and cardiovascular health. Stress is a physiological and psychological response of the human body to internal and external stressors (psychological or physical), which activates the sympathoadrenal system and increases the levels of stress hormones — adrenaline and cortisol. During stress, heart rate accelerates, blood pressure and metabolism change, directly affecting the cardiovascular system. Prolonged chronic stress can lead to inflammatory changes in arterial walls, hypertension, arrhythmias, and ischemic heart disease. Stress management, meditation, breathing exercises, and a healthy lifestyle are important preventive measures for maintaining cardiovascular health.
