Health Impacts of Heat and Air Quality
Heat and poor air quality can significantly affect human health. High temperatures increase the risk of heat exhaustion, heatstroke, and dehydration, especially among vulnerable groups like the elderly and children. Poor air quality, often caused by pollutants and wildfire smoke, can worsen respiratory conditions such as asthma and COPD, and may trigger cardiovascular problems. Together, heat and air pollution can amplify health risks, leading to increased hospitalizations and even premature death.

❓ Frequently Asked Questions
What health problems can result from high temperatures?
Heat exhaustion, heatstroke, and dehydration are common risks during heat waves, along with dizziness and fatigue.
Who is most vulnerable to heat-related health effects?
Older adults, young children, pregnant people, people with chronic illnesses, outdoor workers, and those with limited access to cooling are most at risk.
How can you tell heat exhaustion from heatstroke?
Heat exhaustion: heavy sweating, weakness, dizziness, nausea. Heatstroke: body temp above 103°F (39.4°C), confusion, hot/red/dry skin, rapid pulse—call emergency services.
How does poor air quality affect health?
Air pollutants and wildfire smoke irritate airways, worsen asthma/COPD, and raise cardiovascular risk; symptoms include coughing, throat irritation, and shortness of breath.
What steps can you take to stay safe during hot days and smoky days?
Hydrate regularly, stay indoors in air-conditioned spaces, limit outdoor activity, check the air quality index (AQI), wear appropriate clothing, and use masks or air purifiers indoors when needed.
