Air Pollution
Air pollution is a mix of solid particles and gases in the air. It includes car emissions, factory chemicals, dust, pollen, and mold spores. Ozone, a gas, is a major part of air pollution in cities and is also called smog. Inhaling air pollution can increase the chance of health problems, especially for people with heart or lung disease, older adults, and children.
Symptoms
- Respiratory problems
- Asthma
- Heat illness
- Dehydration
- Febrile state in infants and young children
- Diarrheal and vector-related infections
Causes
Air pollution is caused by car emissions, chemicals from factories, dust, pollen, mold spores, and ozone. It can also come from indoor sources.
Treatment
Lifestyle
- Choose certified supplements
- Diversify food sources
- Make air-quality-informed training decisions
Frequently asked questions
What is air pollution?
Air pollution is a mixture of solid particles and gases in the air, including car emissions, factory chemicals, dust, pollen, mold spores, and ozone (smog).
Who is most at risk from air pollution?
People with heart or lung disease, older adults, and children are at greater risk from air pollution.
Can air pollution affect pregnancy?
Yes, studies show that prenatal exposure to air pollution is linked to low birth weight, preterm birth, and changes in maternal and neonatal thyroid function.
Does air pollution affect children's health?
Yes, air pollution is linked to respiratory problems, asthma, and hospitalizations in children. Heat waves and extreme weather also increase cases of heat illness and infections in children.
Is indoor air pollution a concern?
Yes, air pollution isn't just outside - the air inside buildings can also be polluted and affect your health.
