The Birmingham heatwave is set to hit this weekend, bringing warnings of an "increased risk to life" for four specific groups of people. The UK Health and Security Agency (UKHSA) has confirmed an amber heat health alert for the East of England, London, South East, and South West, while yellow alerts have been issued for the East Midlands and West Midlands.
Health Risks and Warnings
The UKHSA expects "increased use of healthcare services by vulnerable people" and warns of a "greater risk to life of vulnerable people." It also anticipates "increased potential for indoor environments to become very warm" and notes that "water-related incidents may increase, including risks from cold-water shock and drowning."
Four Groups at Increased Risk
In official documentation, the UKHSA states: "EVERYBODY can be affected by high temperatures, but there are certain factors that increase an individual's risk during a heatwave." These factors include:
- Older age: especially those over 65 years old, those living alone, socially isolated individuals, or those in care homes.
- Chronic illnesses: people with heart or lung conditions, diabetes, renal insufficiency, Parkinson's disease, or mental illness.
- Lack of adaptive capabilities: babies and very young children, people with disabilities, those who are bed bound, or those with cognitive or sensory impairment.
- Environmental factors: babies and the very young, people with disabilities, those who are bed bound, excessive alcohol consumption, or those with Alzheimer's disease.
Heatwave Definition and Climate Impact
The Met Office defines a heatwave as a period of at least three consecutive days with daily maximum temperatures meeting or exceeding a region-specific threshold. The UKHSA defines a heat episode for mortality monitoring as any day on which an Amber Heat-Health Alert was issued in at least one region or the mean central England temperature was at least 20°C.
Hot weather poses a significant threat to health in the UK, and the frequency, intensity, and duration of heat episodes are increasing due to climate change. The UKHSA has previously warned that hot weather is a priority risk for urgent action in England.
