In this section, we explore key terms that are fundamental to comprehending the complexities of stress and its management. The term 'stress' refers to the body's reaction to challenging situations, which can be a part of life's challenges. 'Stressors' are the factors that induce stress, including environmental, psychological, and social conditions. 'Coping' involves the strategies and techniques individuals use to manage stress effectively, optimizing their psychological resilience. Concepts such as 'resilience' describe an individual's ability to adapt to adversity and bounce back from challenges, while 'psychoneuroimmunology' studies the connection between psychological processes and the immune system's functioning. This vocabulary not only serves as a foundational framework for discussing stress but also facilitates deeper understanding and application of stress management strategies and promotes the overall well-being of individuals.
