The Impact of Environmental Pollution on Elderly Health and Prevention Methods
If you feel stuffy even with your windows open, and the air feels stale when closed, you're not alone. As we age, our bodies become more sensitive to even the same air quality. This article will explain in detail how environmental pollution affects our health as we age and provide practical preventative measures we can implement in our daily lives. From outdoor habits to home maintenance, exercise, nutrition, and medical care, we've compiled a comprehensive overview of environmental pollution, health in old age, and practical preventative measures.

Why Older Adults Are More Vulnerable to Pollution

Physiological changes in the respiratory and cardiovascular systems
As we age, the protective mucous membranes of the airways and lung elasticity decline, making it easier for irritants like fine dust and ozone to penetrate deeper. Blood vessels also lose elasticity, making them more susceptible to inflammation and constriction. Therefore, even with the same concentration of pollution, the risk of elevated blood pressure, heart rate fluctuations, and chest pain increases.
Effects of comorbidities and medications
If you have a chronic condition like asthma, COPD, heart failure, high blood pressure, or diabetes, or are taking multiple medications, you may be less resilient to environmental stimuli and experience accelerated deterioration. Even minor breathing difficulties or swelling can easily lead to hospitalization in older adults, requiring proactive management strategies.
Major health problems caused by air pollution

Respiratory deterioration
PM2.5, PM10, nitrogen dioxide, and ozone promote airway inflammation, causing coughing, wheezing, phlegm, and shortness of breath, or triggering the exacerbation of existing asthma or COPD. In the elderly, symptoms can rapidly worsen even if they begin mildly, making early intervention crucial.
Cardiovascular burden
Fine dust reduces vascular endothelial function and disrupts blood pressure and heart rate variability, increasing the risk of angina, myocardial infarction, and stroke. If your pulse increases or you feel more out of breath than usual, stop strenuous activity, rest, and record your symptoms.
Neuropsychiatric effects
On days with high levels of pollution, concentration difficulties, headaches, and sleep disturbances may increase. In older adults, poor sleep quality can lead to falls and daytime fatigue, so managing indoor air quality before bed and maintaining a regular sleep routine are crucial.
Home is not a safe zone: How to manage indoor pollution

Identify the culprit and take immediate action
Gas stove use, inadequate ventilation, moisture after showering, mold, and VOCs from new furniture contribute to indoor pollution. Switch to electric or induction cooktops whenever possible, and use a high-volume, external exhaust hood when cooking. Ventilate bathrooms and kitchens for 20 minutes immediately after use, immediately remove mold, and thoroughly repair water leaks.
Indoor Air Quality Improvement Checklist
- Start cooking 5 minutes beforehand and continue cooking for 10-20 minutes afterward.
- Use of HEPA H13 grade air purifiers, ensuring sufficient CADR relative to actual area.
- After blocking leaks from cracks in doors and windows, ventilate 2-3 times for 5-10 minutes each time during times of low pollution.
- Minimize use of detergents and fragrances, and choose low-VOC products.
- Run a dehumidifier or exhaust fan for 20 minutes after showering to remove mold immediately.
- Daily care for pet hair and dust, and wash bedding in hot water.
Going Out Plans and Mask Utilization Strategies

Check air quality index and manage time
Before heading out, check the national air quality app or local alerts for fine dust and ozone levels. Ozone levels are typically highest during the day, so plan your activities early in the morning or after sunset, and choose routes within parks rather than along roads.
Reduce exposure while on the move
When waiting at traffic lights, switch to internal circulation mode and regularly replace the cabin air filter with a high-performance product that meets the specifications. When waiting for public transportation, stand at least 5 to 10 meters away from major roads and avoid facing the bus exhaust vents.
Mask Selection Guide
- KF94·N95 High ultrafine dust blocking ability, making it suitable for days with high pollution
- surgical mask Limited response to fine dust, focusing on blocking droplets
- Face seal is key, reduce the gap with a nose support and replace if it gets wet with sweat.
- If you have difficulty breathing, take a break and divide the wearing time.
Don't stop exercising, just change it up

Indoor Alternative Exercise Routine
On days with high pollution, substitute indoor exercise with stationary cycling, stretching, or resistance band strength training. Breaking it down into 10-minute intervals and performing three sessions will reduce cardiopulmonary strain while still maintaining total exercise volume.
Ventilation and air purifier in parallel
Before and after indoor exercise, choose a time when outdoor pollution is low and ventilate briefly. During exercise, run an air purifier on high wind to reduce the concentration of ultrafine dust.
A protective shield created through nutrition and lifestyle habits
Antioxidant diet and hydration
Consume antioxidant-rich, omega-3 foods daily, such as dark-colored vegetables and fruits, nuts, and fish. Increase your water intake to keep your mucous membranes hydrated. Avoid salty foods, as they can worsen swelling.
Smoking cessation and sleep management
Smoking and secondhand smoke amplify the effects of pollution. Reducing electronic device use and dimming the light two hours before bedtime to maintain quality sleep will improve your ability to recover the next day.
Vaccinations and hand hygiene
Respiratory infections can be a secondary blow to airways weakened by pollution. Get vaccinated against influenza and pneumococcal bacteria, and make it a habit to wash your hands after going out.
Medication, underlying disease management, and medical preparation
Individual deterioration response plan
Patients with asthma or COPD should consult with their healthcare provider and develop a plan of action and precautions for use of back-up medications in case of exacerbations. Patients with heart failure or high blood pressure should record warning signs such as weight fluctuations, ankle swelling, and shortness of breath and share them with their doctor.
No arbitrary changes to medications are allowed.
Even on days with high pollution, do not increase or decrease your medication dose on your own. If respiratory symptoms recur, it's safer to bring your medication schedule and symptom diary with you to see a doctor.
Recording minor inconveniences and making small changes prevents major deterioration. Recording is the best preventative tool.
Home Structure and Community Resource Utilization
Improve your living environment
Reduce leakage with window sealing tape, door seals, and variable-use vents. Ventilate briefly and thoroughly during low-pollution hours. Mold recurrence can be prevented by addressing the source of leaks and condensation, not just removing the surface.
Heat and Cold Wave Shelters and Community Alerts
Check air quality, heat wave, cold wave alerts, and indoor shelter information from local health centers, senior centers, and welfare centers. On days with high pollution, include a nearby indoor shelter in your schedule.
Frequently Asked Questions
Is it okay to wear a KF94 mask all day on a day with high pollution?
Although possible, if you experience shortness of breath, take the mask off and rest briefly indoors. Replace it if it becomes wet or contaminated. Maintaining a close seal with your face is important. If dizziness or chest tightness persists, discontinue use, rest, and consult a medical professional if necessary.
What criteria should I use to choose an air purifier?
Check for HEPA H13 or higher, a sufficient CADR for the indoor space, and filter replacement costs and frequency. Check noise levels, auto mode sensitivity, and compatibility with external exhaust hoods to ensure maximum user satisfaction.
If I keep the windows closed, do I not need to ventilate?
Even indoors, pollution accumulates from cooking, cleaning, and showering. It's effective to ventilate briefly for 5-10 minutes during times when outdoor pollution is low, and use an air purifier to circulate the air at other times.
What's the easiest way to reduce indoor pollution when using a gas stove?
Before turning on the stove, turn on the external exhaust hood on high airflow, use the lowest heat setting possible, use a lid, and switch from grilling to boiling or steaming. In the long term, switching to electric or induction cooking will be beneficial.
I am taking heart medication or diuretics. Do I need to adjust them on days when pollution is severe?
Arbitrary adjustments are dangerous. While taking your medication as usual, record changes in blood pressure, pulse, weight, swelling, and shortness of breath, and consult your doctor. If any abnormal symptoms persist, seek medical attention immediately.
