The UK Health Security Agency (UKHSA) has raised a new alert regarding a growing issue impacting various regions in the UK. According to the health protection body, there is a rise in the number of wildfires occurring in the country, exemplified by the current blaze in the Cairngorms National Park in the Scottish Highlands. Recent data revealed that in 2025, fire and rescue services in England and Wales responded to nearly 1,000 wildfire incidents, surpassing the previous record set in 2022.
In a statement, the UKHSA emphasized the increasing prevalence of wildfires in the UK and the potential health risks associated with the smoke they produce. These wildfires, often fueled by hot and dry weather conditions, have led to what is being termed a ‘firewave’ this year. With the frequency of hotter and drier summers on the rise, understanding the implications of wildfires on health and taking necessary precautions is crucial.
The UKHSA highlighted that wildfires, characterized by uncontrolled vegetation fires requiring emergency response, can quickly spread across grasslands, moorlands, woodlands, and peat. Climate change-induced hotter and drier summers are creating favorable conditions for fires to ignite and rapidly propagate. The agency stressed the importance of adhering to wildfire prevention guidance issued by the Fire and Rescue Service, as most wildfires are human-caused and pose risks to communities and emergency services.
Wildfire smoke contains various pollutants such as fine particles, carbon monoxide, nitrogen oxides, and volatile organic compounds which can severely impact respiratory health. Individuals with pre-existing conditions like asthma, heart disease, or respiratory issues are particularly vulnerable to the harmful effects of wildfire smoke. The UKHSA advised that staying indoors with closed doors and windows during a nearby wildfire is the most effective way to minimize exposure to smoke.
For those driving through smoky areas, it is recommended to keep windows closed, air vents shut, and use recirculate mode on the air conditioning. The agency warned that smoke inhalation can lead to respiratory discomfort and chest pain, especially for vulnerable groups. Anyone experiencing persistent symptoms should seek medical advice promptly.
In the event of a wildfire nearby, following emergency service instructions is crucial as fires can rapidly escalate and pose a significant threat to life and property. The UKHSA advised residents to avoid areas affected by smoke and remain indoors with doors and windows shut to reduce smoke exposure. Additionally, individuals with asthma should follow their action plans and ensure access to prescribed medications.
Firefighters are currently battling a wildfire in the Cairngorms, prompting evacuations in the area as a precautionary measure. The fire, which originated in heathland near Nethy Bridge, has spread rapidly, necessitating continuous efforts to contain it. While several properties have been evacuated, there have been no reported casualties.
