Study Notes
- The text discusses both the physical benefits and hazards of being exposed to various forms of energy in the environment.
- Physical benefits can come from natural sources such as the land and can have psychosocial and spiritual effects, or biophilia and connection with nature.
- Physical hazards can come from both natural and anthropogenic sources, such as radioactive material and sound waves.
- Common environmental hazards include noise and radiation, and can have significant impacts on Indigenous populations due to occupation, livelihood, age, previous health conditions, and geographic location.
- Radiation is a form of energy that can ionize atoms or molecules and can cause health effects such as thyroid cancer, leukemia, and heritable effects.
- Sources of radiation include nuclear power plants, nuclear weapons, and uranium mining.
- Non-ionizing radiation, such as ultraviolet radiation and electromagnetic fields, can also have health effects such as skin cancer, immunosuppression, and cataracts.
- Organisms, including humans, must maintain a fairly constant internal environment, known as homeostasis, to survive.
- Climate and temperature play a significant role in health and well-being, and can have both positive and negative effects through feedback mechanisms.
- Climate change can have both direct and indirect health effects, with negative consequences including heat stroke and cardiac mortality, and positive consequences including increased physical activity and access to resources.
- Connection with physical energy in the environment can have numerous health benefits, including improved mental and spiritual health, cultural identity, and social well-being.
