Health advisory as haze lingers and affects air quality in Seychelles |20 February 2025

The Ministry of Health is alerting the public to the persistent haze affecting Seychelles over the past several days, resulting in unhealthy air quality levels, as reported by the aqicn Air Pollution Monitoring System.

This decline in air quality is linked to some people, particularly among vulnerable populations, experiencing respiratory issues.

Situation overview

The haze, caused by a combination of atmospheric conditions and potential transboundary pollutants, has elevated particulate matter levels in the air. These fine particles pose certain health risks, especially to children, the elderly, pregnant individuals, and those with pre-existing respiratory or cardiovascular conditions such as asthma, chronic obstructive pulmonary disease (COPD), or allergies. Long-term

effects of such short-term exposures are unknown.

Health advisory

Symptoms associated with prolonged exposure to poor air quality include:

• Coughing, wheezing, or shortness of breath

• Irritation of the eyes, nose, or throat

• Worsening of allergy symptoms (sneezing, runny nose)

• Fatigue or dizziness

• Increased risk of respiratory infections

Healthy individuals may experience discomfort during periods of reduced air quality. Those at higher risk (as described above) are more likely to see a worsening of their symptoms and should take extra care.

Preventive measures for the public

To minimise health risks, the ministry advises the following:

1. Limit outdoor exposure:

• Avoid prolonged outdoor activities, especially during peak haze hours (midday to evening).

• Reschedule non-essential activities like exercise or gardening.

2. Keep indoor air clean:

• Close windows and doors; use air conditioning where possible on recirculation mode.

• Avoid indoor pollutants (e.g., cigarette smoking, burning candles, mosquito coils, aerosol sprays).

3. Stay hydrated:

• Drink water frequently to help flush irritants from your system.

4. Monitor health:

• Individuals with chronic conditions should ensure medications (e.g. inhalers, antihistamines) are readily available.

• Seek medical attention immediately if symptoms worsen (e.g., severe breathing difficulties, chest pain).

All residents, especially vulnerable groups, are encouraged to follow these guidelines. These simple measures will help during this temporary situation.
