As climate change intensifies, new research highlights how extreme temperatures are straining healthcare systems and affecting public health.
Extreme temperatures-both hot and cold-are taking a significant toll on human health, according to a study by Michael Cohen and Chanie Suttner, actuaries at Discovery Health. The research reveals that very high and low temperatures are leading to spikes in doctor visits, emergency care, and hospital utilization. This finding underscores the urgent need for healthcare systems to adapt to the growing impacts of climate change.
The study, presented at the HIMSS26 European Health Conference and Exhibition, analyzed data from various regions and found consistent patterns. During periods of extreme heat or cold, there is a notable increase in the number of people seeking medical attention. This surge puts additional pressure on healthcare resources, which can already be stretched thin during normal conditions.
Extreme temperatures affect different populations in distinct ways. For instance, elderly individuals and those with pre-existing health conditions are particularly vulnerable to heatwaves. Heat stress can exacerbate cardiovascular and respiratory issues, leading to more hospitalizations. Similarly, cold snaps can increase the risk of hypothermia and other cold-related illnesses, especially among homeless individuals and those living in poorly insulated homes.
Michael Cohen, one of the study’s authors, explains that these findings are not just about individual health but also about the broader healthcare system. "When extreme temperatures hit, we see a significant uptick in healthcare demand," he says. "This can overwhelm hospitals and clinics, leading to longer wait times and reduced quality of care for everyone."
The research also highlights the economic implications of these temperature-related health issues. Increased healthcare utilization translates into higher costs for both patients and healthcare providers. This financial burden can be particularly沉重 for low-income families who may struggle to afford medical bills.

To better prepare for the challenges posed by climate change, experts are exploring innovative approaches like exposomics. Exposomics is a field that aims to map all environmental exposures an individual encounters throughout their life, from air pollution to chemical toxins. By integrating this data with genetic and clinical information, healthcare providers can gain a more comprehensive understanding of how environmental factors influence health.
Manolis Christodoulakis, a Member of the Hellenic Parliament for East Attica and Environment, emphasizes the importance of this approach. "Exposomics provides a transformative framework for strengthening healthcare systems," he says. "It allows us to enhance disease surveillance, detect issues early, and tailor interventions more precisely."
This holistic view can help identify at-risk populations and implement targeted prevention strategies. For example, communities with high levels of air pollution might benefit from public health campaigns that focus on reducing exposure and improving indoor air quality. By addressing the root causes of environmental health risks, healthcare systems can become more resilient and effective.
The human cost of extreme temperatures is profound. Beyond the immediate health impacts, there are long-term consequences for individuals and communities. For instance, repeated hospitalizations due to heat or cold-related illnesses can lead to chronic conditions, reduced quality of life, and even premature death.
Chanie Suttner, co-author of the study, underscores the need for a multi-faceted approach to address these issues. "We must invest in both healthcare infrastructure and public health education," she says. "This includes improving access to cooling centers during heatwaves and ensuring that homes are adequately insulated against cold."
Ultimately, the research by Cohen and Suttner serves as a wake-up call for policymakers and healthcare providers. As climate change continues to alter our environment, it is essential to develop strategies that protect vulnerable populations and ensure the sustainability of healthcare systems. By doing so, we can mitigate the human cost of extreme temperatures and build a healthier future for all.

About the author
Amara's entry point into AI was an epidemiology role at a London research hospital, where she spent five years studying how digital health tools reached — or conspicuously failed to reach — underserved communities. Watching early algorithmic systems in healthcare quietly entrench existing inequalities, she redirected her career toward the systemic consequences of AI at scale. She covers AI through an unflinching lens: who benefits, who bears the cost, and what evidence actually says versus what the press release claims. Her writing is calm and precise, but she doesn't mistake balance for neutrality.
