'Acrid smell' across Leeds: AccuWeather issues air quality alert as heatwave triggers asthma warnings
As residents in Leeds notice an acrid smell during the UK heatwave, AccuWeather data flags elevated air pollutants that could spell trouble for asthma sufferers
With a heatwave still taking place across the United Kingdom, those in Leeds with their windows wide open might be noticing an acrid smell - be it exhaust fumes, wildfires or roadworks including road resealing.
Which could spell real problems for those who have respiratory issues, including asthma.
AccuWeather is currently reporting that today, the Air Quality Index (AQI) across Leeds sits at 24 ('Fair').
While the overall rating is considered generally acceptable for the majority of the population, specific pollutants trapped close to the ground are flagging concerns for sensitive groups.
Both Nitrogen Dioxide and fine particulate matter are currently sitting at 'Fair' levels across the city.
During hot weather, still air and atmospheric inversions trap microscopic dust, chemical fumes, and smoke particles near ground level rather than letting them disperse.
Combined with high temperatures, these trapped particles can aggravate airways and trigger sudden flare-ups.
How Trapped Pollutants Affect Respiratory Health
According to guidance from Asthma + Lung UK and the NHS, hot weather paired with elevated pollutant levels creates a double threat for lungs:
- Particulate Irritation: Fine particulate matter consists of microscopic particles small enough to penetrate deep into the lungs and bloodstream. Exposure can cause coughing, chest tightness, and aggravated asthma symptoms.
- Chemical Exposure: Nitrogen Dioxide from vehicle exhausts and burning materials irritates the linings of the airways, increasing the risk of respiratory infections and shortness of breath.
- Airway Contraction: Inhaling hot, stagnant air can cause sensitive airways to narrow rapidly, making breathing feel significantly harder.
Official NHS & Asthma + Lung UK Advice
Health authorities recommend several practical measures for sensitive groups when warm air quality dips:
- Keep Reliever Inhalers Close: If you or a family member has asthma or COPD, ensure your blue reliever inhaler is carried with you at all times.
- Timing Outdoor Activity: Avoid strenuous outdoor exercise between 11am and 3pm, when heat, sunlight intensity, and atmospheric stagnation are at their peak.
- Avoid Main Roads: Vehicle exhaust is a primary source of Nitrogen Dioxide. Where possible, stick to quieter side streets, shaded parks, or less congested pathways.
- Manage Indoor Ventilation: If acrid smells or hot air are entering through open windows, keep blinds closed on the sunny side of the house during peak heat hours. Reopen windows late in the evening when outdoor temperatures drop and air clears.
- Stay Hydrated: Drink plenty of cold water throughout the day to keep airways moist and help the body regulate heat.
If you or someone around you experiences severe breathlessness, chest pain, or an asthma attack that does not respond to a reliever inhaler, seek immediate medical attention via NHS 111 or call 999 in an emergency.
