What encompasses physical agents in the context of environmental health?

Physical agents in the context of environmental health refer to elements in the environment that can affect human health through direct physical means. This includes factors such as noise, temperature, radiation, and other forms of physical stimuli that can have an impact on health outcomes. Noise can cause hearing loss, stress, and other health problems, while extreme temperatures can lead to heat exhaustion or hypothermia, illustrating how these physical agents directly influence well-being.

The other options address different aspects of health but do not fall under the category of physical agents. Human interactions with technology refer to socio-technical systems and their impact on life quality, financial resources relate to socioeconomic status affecting access to health services, and psychological factors pertain to mental health and well-being rather than physical environmental conditions. Hence, the most accurate choice that aligns directly with the definition of physical agents is the one that includes noise and temperature.
