Recent data released by NHS England highlights a troubling trend: July’s two heatwaves were instrumental in driving an alarming 2.5 million visits to Accident & Emergency (A&E) departments across the UK. As healthcare professionals grapple with the consequences of extreme temperatures, the strain on both patients and NHS staff becomes increasingly evident.
Heatwave-Related Health Issues on the Rise
Dr. Adrian Boyle, an A&E consultant at Addenbrooke’s Hospital in Cambridge, has observed a significant uptick in injuries among elderly patients during the summer months. “The primary issue we are seeing in A&E during extreme heat is falls among older individuals,” he remarked. He described distressing cases where elderly patients, often on diuretics or medications for hypertension, became dizzy and fell, resulting in serious injuries such as broken ribs and limbs. One particularly severe incident involved a patient who tumbled down a flight of stairs, sustaining multiple fractures.
This pattern, according to Dr. Boyle, is exacerbated by the heat, which can lead to dehydration and subsequent health complications. “I’ve witnessed an increase in kidney failure cases due to dehydration, as well as dangerous drowning incidents among young people who swim in unregulated areas to escape the heat,” he added. Individuals on medications for severe mental illnesses are also at heightened risk, as their treatment may impair their ability to perceive rising temperatures.
A&E Departments Overwhelmed
The impact of the heatwaves is starkly reflected in NHS statistics, which indicate that the first two heatwaves of the summer contributed to nearly 2,877 heat-related fatalities—almost double the 1,504 deaths recorded in 2025. The NHS’s report underscores that many of the 2.5 million A&E visits in July stemmed from exacerbated respiratory issues and other pre-existing health conditions worsened by the oppressive heat.
Dr. Boyle expressed concern about the limitations of the healthcare system to accommodate patients during extreme weather. “Our hospitals and ambulances are not equipped to manage heat-related illnesses effectively,” he stated. With inadequate air conditioning in many hospital wards, patients may experience further distress, compounding their original health issues. “It’s uncomfortable for patients lying on plastic mattresses, especially in these conditions,” he noted.
Staff Challenges Amidst Rising Temperatures
The toll of extreme heat extends beyond patients to healthcare staff as well. Dr. Zuzanna Sawicka, a consultant in elderly medicine and the Royal College of Physicians’ clinical director for patient safety, described the challenges faced by medical personnel wearing personal protective equipment (PPE). “Working in full PPE during hot weather is stifling and limits the duration of patient interactions,” she explained. The discomfort can become a health hazard for staff, especially in cases requiring extended engagement with patients.
Jean, a nurse at a London hospital, echoed this sentiment. “While we do have some fans, they are insufficient for the number of patients we have. This leads to tension, as patients compete for a bit of relief from the heat,” she said. The uniform worn by nurses adds to the discomfort, as many have found their attire too thick for the sweltering conditions. “We have been requesting lighter uniforms for ages, but nothing has changed,” she lamented.
The Broader Implications of Extreme Weather
The recent heatwaves have cast a spotlight on the intersection of climate change and public health. As the UK grapples with increasingly frequent and severe weather patterns, the implications for healthcare systems are profound. The NHS’s ability to respond effectively in times of crisis is jeopardised by infrastructural inadequacies and resource limitations.
Why it Matters
The effects of extreme heat on public health cannot be overstated. With rising temperatures leading to increased hospital visits and strain on healthcare providers, it is imperative that the NHS and policymakers address these challenges proactively. Failure to adapt to the realities of climate change could result in a healthcare system that is ill-equipped to protect vulnerable populations, particularly the elderly and those with pre-existing health conditions. As we face the likelihood of more intense heatwaves in the future, the need for improved resources and infrastructure will become even more crucial in safeguarding public health.
