    Health issues explained

    Health is a complete state of physical and mental well-being, not simply the absence of disease or infirmity.

    Read the full explanation

    Physical well-being includes having a healthy body that functions properly, free from illness and injury. Mental well-being includes feeling positive about oneself, being able to cope with normal stresses, and having good emotional and social functioning. For example, a person with a broken leg has physical ill health, while someone experiencing depression has mental ill health. Both aspects are equally important and can influence each other. A person may have no diagnosed disease but still feel unwell mentally, or may have a physical condition but maintain good mental well-being. This holistic definition is used by the World Health Organization and is central to understanding health issues.

    Your focus

    1. State the definition of health.
    2. Describe what is meant by physical and mental well-being.
    3. Explain why health is not just the absence of disease.

    Common Mistakes
    • Defining health as only physical fitness; correction: health includes mental well-being as well.
    • Thinking that if you are not ill, you are healthy; correction: health also requires mental well-being, so you could be physically well but mentally unwell.
    • Confusing mental well-being with mental illness; correction: mental well-being is a positive state, while mental illness is a diagnosed condition.
