The Increasing Impact of Heatwaves: A Global Health Challenge

The harsh reality of climate change is becoming increasingly apparent, with extreme temperatures emerging as an increasing global phenomenon. One of the most conspicuous manifestations of this climatic shift is the occurrence of heatwaves. These bouts of extreme heat aren't just uncomfortable, they also pose significant health risks and can increase death rates; particularly amongst the most vulnerable people in societies - such as the elderly, children, and individuals with pre-existing health conditions.

Heatwaves don't just affect the health of individuals; they also put enormous strain on healthcare systems. In times of extreme temperatures, the influx of patients seeking medical help for heat-related illnesses increases drastically. Often, other factors linked with extreme heat, like water shortages and poor air quality, exacerbate the situation, leading to an even greater health crisis.

The ability to effectively manage these health threats often comes down to the resources and infrastructure a country has in place. Countries with advanced infrastructures are typically better equipped to handle these challenges. They can provide the necessary healthcare, deploy strategies to keep the population cool, and improve the urban infrastructure to mitigate the impact of high temperatures. .

However, for lower-income countries, the picture isn't as bright. In such countries, which regularly experiences high temperatures and have less developed infrastructure, the challenge is significantly more daunting. It's much more difficult for these nations to provide the level of healthcare required during a heatwave or to put strategies in place to protect the population from the extreme heat.

This makes it even more imperative for such regions to establish robust measures to mitigate the health impacts of climate change and extreme heat. The strategies needed are wide-ranging - from improving their healthcare systems and response to heat-related illnesses, to launching comprehensive climate adaptation and mitigation policies. These actions are not just necessary, they are urgent, because when it comes to heatwaves and the health threats they bring, we are all feeling the impact.

What is the difference between primordial prevention and primary prevention?

Primordial prevention and primary prevention are both crucial strategies for promoting health, but they operate at different levels. Primordial prevention aims to address the root causes of health problems and improve the wider determinants of health. It focuses on preventing the emergence of risk factors in the first place by tackling the underlying social, economic, and environmental determinants of health. This involves broad, population-wide interventions such as: Policies that promote healthy food choices: Think about initiatives like taxing sugary drinks to discourage unhealthy consumption, or providing subsidies for fruits and vegetables to make them more accessible. Urban planning that prioritises well-being: This could include creating walkable neighborhoods with safe cycling routes, ensuring access to green spaces for recreation and relaxation, and designing communities that foster social connections. Social programs that address inequality: Initiatives aimed at reducing pov...

What makes a good doctor – and who gets to decide?

What Makes a Good Doctor? This is the question that Waseem Jerjes and I explore in the Journal of the Royal Society of Medicine . It is a key question that underpins the architecture of medical education, clinical practice, regulation, and professional identity. It cannot be answered by regulators, educators, or employers in isolation. It must be answered together – by doctors and patients – revisited throughout a career, and adapted as society and the profession change. Without that shared reflection, the danger is not simply disillusionment, but the erosion of the moral foundations of clinical work. As we enter an era when diagnosis will increasingly involve artificial intelligence and when performance metrics reward volume over value, reclaiming this question as a professional one is imperative. The integrity of our institutions – and of the practitioners within them – depends on reimagining excellence in inclusive, relational terms. A good doctor is not a flawless technician or a f...

Relevance Over Recall: Rethinking How AI Uses Clinical Data

Our article in the Journal of the Royal Society of Medicine argues that safe and effective AI in healthcare must incorporate mechanisms that emulate human judgement - down-weighting old, inaccurate or superseded information and prioritising what is recent, clinically relevant and reaffirmed - so that AI supports, rather than disrupts, high-quality patient care.  Clinicians constantly revise, reinterpret and filter past information so that only what is relevant, accurate and timely shapes present-day management decisions; medical records function as dynamic “working tools” rather than fixed archives. By contrast, many AI systems lack this capacity for selective forgetting and often treat all historical data as equally meaningful.  This can lead to outdated or low-confidence diagnoses being repeatedly resurfaced, persistent labels influencing clinical expectations, and irrelevant, long-resolved events cluttering summaries and decision-support outputs. Such indiscriminate recall...
