Concept: What is Health?

Dimensions of Wellness

Health is a dynamic condition reflecting the state of a person's body and mind, in the absence or presence of disease and injury. Wellness is the ability to make choices toward optimal health. The concept of wellness includes several interrelated dimensions that contribute to overall health.

• Physical Wellness: Involves maintaining a healthy body through regular exercise, proper nutrition, and avoiding harmful habits.

• Emotional Wellness: Involves understanding and managing feelings, coping effectively with stress, and maintaining a positive outlook.

• Intellectual Wellness: Involves engaging in creative and stimulating activities, expanding knowledge, and critical thinking.

• Social Wellness: Involves developing healthy relationships, effective communication, and contributing to the community.

• Spiritual Wellness: Involves having a sense of purpose, values, and meaning in life, which may or may not include religious beliefs.

• Environmental Wellness: Involves recognizing the impact of your surroundings on your health and taking action to protect yourself and the environment.

• Financial Wellness: Involves managing resources to live within your means and planning for future financial stability.

Example: Rachel is advocating for recycling in her neighborhood, which demonstrates environmental wellness.

Life Expectancy

Life expectancy is a statistical measure of the average number of years a person is expected to live, based on current mortality rates. Advances in medicine, vaccines, antibiotics, and health policy have increased life expectancy over time.

• Life Expectancy: The average number of years a person is statistically expected to live.

• Factors Influencing Life Expectancy: Genetics, economic status, access to health care, lifestyle choices, and environmental factors.

• Not Significant: Hair color is not a significant factor in determining life expectancy.

Example: A person living in poverty may have reduced access to health care and nutritious food, which can lower life expectancy.

Human Diseases and Their Impact

Diseases can be classified as chronic (long-term, non-infectious) or infectious (caused by pathogens and transmissible). Chronic diseases such as cardiovascular disease, cancer, diabetes, and Alzheimer's disease are major contributors to mortality. Infectious diseases include influenza, tuberculosis, malaria, and HIV/AIDS.

Example: HIV is an infectious disease caused by a virus, while diabetes is a chronic, non-infectious disease.

Key Definitions and Concepts

• Health: A state of complete physical, mental, and social well-being, not merely the absence of disease or infirmity.

• Wellness: An active process of becoming aware of and making choices toward a healthy and fulfilling life.

• Life Expectancy Formula:

• Chronic Disease: A long-lasting condition that can be controlled but not cured.

• Infectious Disease: A disease caused by organisms such as bacteria, viruses, fungi, or parasites.

Practice Questions and Applications

• Physical, emotional, and environmental wellness are all important for overall health.

• Life expectancy is influenced by genetics, economic status, and access to health care, but not by hair color.

• Chronic diseases tend to have a greater impact on life expectancy than infectious diseases in developed countries.

Example: A person who recovers from a catastrophic accident can regain physical wellness through rehabilitation and support, demonstrating the dynamic nature of health.
