Which aspect of the environment is considered a physical factor affecting health?

The quality of air and water is a fundamental physical factor affecting health because it directly impacts the well-being of individuals and communities. Clean air is essential for respiration and overall bodily functions, while clean water is critical for hydration, sanitation, and the prevention of diseases. Poor air quality can lead to respiratory issues, cardiovascular diseases, and other health problems, while contaminated water can cause gastrointestinal infections and other serious health concerns. Hence, monitoring and maintaining the quality of these two elements are key to ensuring public health and safety. This focus on tangible environmental aspects aligns with broader health guidelines and standards that emphasize the importance of a clean and safe living environment.
