9.6 Environmental Health

Notes

Environmental health looks at how surroundings affect health, including air, water, soil, noise and climate.

• Air pollution (from vehicles, factories and smoke) can trigger asthma and lung problems. The Air Quality Index (AQI) tells you when to limit outdoor activity.
• Water must be clean. Water treatment removes germs, and unsafe water can spread illness. Lead in old pipes or paint is harmful, especially to children.
• Climate and heat: extreme heat can cause heat illness. Stay hydrated, seek shade and check on neighbors.
• Noise: loud sounds over time can damage hearing. Keep volume lower on headphones.
• UV radiation from the sun raises skin cancer risk.
• Reduce, reuse, recycle and walking, biking or taking public transit lower pollution.
• Healthy environments include green spaces, safe sidewalks and clean housing.
