Climate change and health are now closely linked, no longer just a topic for policy discussions but a reality shaping healthcare systems and patient outcomes. Physicians are seeing shifts in disease patterns, with more climate-related conditions and rising climate-related health risks adding pressure to already stretched healthcare systems. This is driving the need for better clinical preparedness, clearer patient education, and a stronger focus on sustainable healthcare practices, while also emphasising the growing role of physicians in climate change and healthcare market research.
Rising temperatures are contributing to more frequent heat-related illnesses, particularly among vulnerable populations such as elderly patients, children, and those with chronic conditions. At the same time, worsening air quality is linked to respiratory and cardiovascular complications, while changing environmental conditions are altering the spread of infectious diseases. These changes are not isolated events but part of a broader pattern that is gradually reshaping clinical practice*.
This blog explores the following key areas:
Climate Change as a Healthcare System Challenge
The impact of climate change on healthcare extends far beyond individual patient conditions. It is fundamentally altering how healthcare systems operate, plan, and respond to both routine and emergency situations. These changes are creating pressures that affect infrastructure, workforce capacity, and the continuity of care delivery.
According to the World Health Organization, climate change is expected to result in approximately 250,000 additional deaths per year between 2030 and 2050. These deaths are associated with conditions such as undernutrition, malaria, diarrhoeal disease, and heat stress. While these figures highlight the direct health impact, they only represent part of the broader challenge*.
Healthcare systems are also facing operational disruptions. Extreme weather events can damage infrastructure, interrupt supply chains, and limit access to essential services. For example, flooding may restrict patient access to hospitals, while heatwaves can increase electricity demand, placing pressure on energy systems that healthcare facilities rely on. These disruptions can lead to delays in treatment, increased workload for healthcare staff, and reduced system efficiency*.
Another key challenge is the unpredictability of demand. Climate-related events can cause sudden spikes in patient volume, particularly in emergency and acute care settings. This requires healthcare systems to be flexible and responsive, with contingency plans in place to manage surges effectively.
Within this context, physicians play a critical role. They are often the first point of contact for patients and have direct insight into how these systemic pressures translate into clinical realities. Their experiences provide valuable information that can inform both immediate responses and long-term planning. As healthcare systems adapt to climate-related challenges, understanding and integrating physician perspectives becomes increasingly important.
Where Physicians See Their Role
To explore how clinicians perceive their role in addressing climate-related health impacts, the M3 Pulse survey asked 2927 physicians the following question : Which of the following areas do you believe physicians can most realistically contribute to when addressing the health impacts of climate change?
Out of the given options the results show that 33% of physicians identified patient education and counselling as their primary area of contribution. This was followed by 26% who selected support for sustainable practices within healthcare settings, highlighting a growing awareness of environmental responsibility within clinical environments. Smaller proportions of respondents pointed to clinical preparedness (13%), participation in system planning (10%), and research or data collection (10%). Notably, 7% of physicians indicated that they do not believe they can meaningfully contribute at present, suggesting perceived barriers or limitations.
These findings reflect an important insight. Physicians are not necessarily viewing their role in terms of large-scale policy or systemic change. Instead, they are focusing on areas where they already have influence, particularly in patient interactions and day-to-day clinical practice.
This perspective is significant because it highlights a realistic and grounded approach. Rather than expecting physicians to take on entirely new responsibilities, it suggests that their contribution to climate-related health challenges can be integrated into existing workflows. Patient education, clinical awareness, and operational efficiency are all areas where physicians already play a central role.
At the same time, the lower percentages for system planning and research suggest that there may be opportunities to better support physician involvement in these areas. Providing clearer pathways, resources, and guidance could help expand their contribution beyond immediate clinical settings while still respecting the constraints of their workload.

Patient Education as a Frontline Response
Patient education stands out as the most widely recognised area where physicians can contribute. This aligns closely with the core responsibilities of clinical practice, where communication, guidance, and preventive care are essential components of patient management.
Physicians are often seen as trusted sources of information, particularly when it comes to health risks and preventive measures. This places them in a strong position to raise awareness about how climate-related factors can affect health. For example, during periods of extreme heat, physicians can advise patients on hydration, recognising early signs of heat exhaustion, and adjusting medications if necessary. Similarly, they can provide guidance on managing respiratory conditions during periods of poor air quality*.
Importantly, patient education does not require significant changes to existing workflows. It can be incorporated into routine consultations, making it a practical and scalable approach. Over time, these small interactions can have a meaningful impact on patient outcomes, particularly for those who are most vulnerable.
Another key aspect of patient education is its role in prevention. By helping patients understand the link between environmental factors and health, physicians can encourage behaviours that reduce risk. This may include lifestyle adjustments, improved self-monitoring, or timely medical intervention.
In addition, patient education contributes to broader public health awareness. As more patients become informed about climate-related health risks, this knowledge can extend beyond individual consultations and influence community-level understanding.
Overall, the emphasis on patient education reflects a pragmatic approach. It allows physicians to make a direct and measurable impact without requiring additional resources or structural changes, making it one of the most effective ways to address climate-related health challenges within current clinical practice.
Sustainable Practices Within Healthcare Settings
The second most selected area, supporting sustainable practices within healthcare settings, reflects an increasing awareness of the environmental impact of healthcare operations. Hospitals and clinics are resource-intensive, consuming large amounts of energy, water, and materials. As climate change becomes a more immediate concern, there is growing recognition that healthcare systems themselves must contribute to sustainability efforts.
Physicians may not be directly responsible for organisational policies, but they can influence practices within their immediate environment. This includes making decisions that reduce unnecessary resource use, such as avoiding redundant tests, optimising treatment pathways, and supporting efficient workflows. These actions, while small individually, can collectively contribute to more sustainable healthcare delivery*.
Sustainable practices also align with broader healthcare priorities, including cost efficiency and quality improvement. Reducing waste and improving resource management can lead to better use of available capacity, benefiting both patients and healthcare systems.
Another important aspect is collaboration. Physicians often work closely with multidisciplinary teams, including nurses, administrators, and support staff. By encouraging sustainable practices within these teams, they can help create a culture of awareness and responsibility.
In some cases, healthcare organisations are already implementing sustainability initiatives, such as reducing single-use plastics, improving energy efficiency, or transitioning to digital systems. Physician support and engagement can help reinforce these efforts and ensure they are integrated into everyday practice.
This area highlights an evolving perspective where clinical roles are no longer limited to patient care alone. Instead, they are increasingly connected to the broader functioning of healthcare systems, including their environmental impact.
The Role of Healthcare Market Research
Healthcare market research plays an important role in understanding how climate change is affecting clinical practice and healthcare systems. By collecting insights from physicians across different regions and specialties, it provides a broader view of emerging trends and challenges.
Physicians contribute to this process by sharing their experiences, observations, and perspectives. This information helps identify patterns, such as changes in disease prevalence, operational challenges, and areas where additional support may be needed.
One of the key advantages of healthcare market research is that it allows physicians to contribute without significantly increasing their workload. Participation is structured and focused, making it a practical way to share insights while continuing clinical responsibilities.
The findings from healthcare market research can inform decision-making across multiple levels. Healthcare organisations can use this data to improve planning and resource allocation, while industry stakeholders can better understand real-world needs.
As climate change continues to evolve, ongoing data collection and analysis will be essential. Physician input ensures that this information is grounded in real clinical experience, making it more relevant and actionable.
Understanding the Perceived Limitations
Time is one of the most significant factors. Physicians often work in high-pressure environments with demanding schedules, leaving limited capacity to engage in additional activities. Workload pressures can make it difficult to prioritise issues that are perceived as outside immediate clinical responsibilities.
There may also be uncertainty about how individual actions contribute to broader outcomes. Without clear guidance or visible impact, physicians may question the value of their involvement.
Institutional factors can also play a role. In some cases, there may be limited support or resources available to address climate-related challenges within healthcare settings.
Recognising these limitations is important for developing effective solutions. Providing clear guidance, practical tools, and accessible opportunities for engagement can help address these barriers.
Looking Ahead: A Shared Responsibility
The relationship between climate change and health will continue to evolve, shaping both clinical practice and healthcare systems. Addressing these challenges requires a coordinated approach that involves multiple stakeholders.
Physicians are already contributing in meaningful ways, particularly through patient education and sustainable practices. These contributions demonstrate that impactful action does not always require large-scale changes but can be integrated into existing roles.
At the same time, there is an opportunity to expand involvement through healthcare market research, system planning, and ongoing education. By supporting physicians and providing clear pathways for engagement, healthcare systems can strengthen their overall response to climate-related challenges.
Ultimately, climate change is not solely an environmental issue but a healthcare challenge that requires shared responsibility. Physicians, healthcare organisations, and industry stakeholders all have a role to play in ensuring that healthcare systems remain resilient, responsive, and capable of delivering high-quality care in a changing environment.
