Causes and Impacts of Indoor Air Pollution

While outdoor air pollution receives considerable attention, indoor air pollution poses a greater threat to human health due to the extended time spent indoors.

Sources of Indoor Air Pollution

  • Combustion sources: Smoking, burning candles, and using fireplaces release harmful pollutants like carbon monoxide, nitrogen oxides, and particulate matter.
  • Building materials and furnishings: Chemicals found in paints, carpets, and furniture can off-gas, releasing volatile organic compounds (VOCs) that aggravate respiratory issues.
  • Household products: Cleaning supplies, air fresheners, and pesticides often contain VOCs and other harmful substances.
  • Biological contaminants: Mold spores, dust mites, and pet dander can trigger allergies and respiratory problems.

Impacts of Indoor Air Pollution on Humans

Indoor air pollution poses significant health risks, especially when exposure is prolonged. 

1. Respiratory Issues

  • Short-term: Irritation of the airways, coughing, and difficulty breathing.
  • Long-term: Chronic respiratory diseases like asthma, chronic obstructive pulmonary disease (COPD), and an increased risk of lung cancer.

2. Cardiovascular Problems

  • Short-term: Temporary increases in blood pressure or heart rate.
  • Long-term: Increased risk of heart diseases, including heart attacks and strokes.

3. Neurological Effects

  • Short-term: Headaches, dizziness, and fatigue.
  • Long-term: Potential links to neurodegenerative diseases like Alzheimer’s and Parkinson’s due to certain types of pollutants.

4. Allergic Reactions and Sensitivities

  • Short-term: Allergic reactions include sneezing, runny nose, and itchy eyes.
  • Long-term: Development or worsening of allergic conditions and hypersensitivity.

Encourage cross-ventilation by opening windows and doors, allowing fresh outdoor air to circulate and dilute indoor pollutants.

Install and maintain exhaust fans in kitchens and bathrooms to expel pollutants generated during cooking or bathing. Also, using a humidifier to keep dry air in check will be a good idea.

2. Manage Household Products

Opt for paints, adhesives, and cleaning products labeled as low-VOC or VOC-free to minimize the release of harmful chemicals.

Store household chemicals, such as solvents and pesticides, in well-ventilated areas away from living spaces.

3. Address Tobacco Smoke

If smoking is unavoidable, designate a specific area outdoors to minimize the infiltration of harmful smoke indoors. Encourage smoking cessation, as it improves individual health and significantly reduces indoor air pollution.

4. Control Moisture and Prevent Mold

Use dehumidifiers in damp areas to control humidity levels, preventing mold growth. Address leaks and water damage promptly to prevent mold infestations, which can release allergenic spores into the air.

5. Regular Cleaning Practices
