Understanding the Impact of Heatwaves on UK Care Homes: A National Survey of Staff Experiences, Challenges, and Adaptation Strategies

A national survey of 225 UK care home staff reveals that while heatwaves significantly compromise thermal comfort and health for both employees and residents, effective adaptation is currently hindered by critical barriers including funding limitations, inadequate infrastructure, and staffing pressures.

The Gist

Imagine a care home as a large, old house where elderly residents live and a team of dedicated staff works around the clock to keep them safe and happy. Now, imagine that house is slowly turning into an oven during the summer.

This research paper is like a "report card" from the people actually living and working inside that oven. The authors asked 225 staff members across the UK and Ireland: "How hot is it really? What are you doing about it? And why is it so hard to fix?"

Here is the story of what they found, explained simply.

1. The "Oven" Effect

The study found that during heatwaves, the care homes are getting dangerously hot.

• The Staff's Experience: Two-thirds of the workers said they feel "too hot" at least three times a day. It's not just uncomfortable; it's like trying to run a marathon while wearing a heavy winter coat. They said this heat makes it harder for them to do their jobs, like helping residents eat, move, or take medicine.
• The Residents' Experience: The staff noticed the residents are suffering too. Even though older people sometimes don't feel the heat as sharply as younger people (their internal "thermostat" is a bit broken), the staff saw that the heat was hurting the residents' comfort and health.

The Analogy: Think of the care home staff as firefighters. Usually, they are trained to put out fires. But in this case, the "fire" is the heat itself, and the firefighters are standing in the middle of the blaze, trying to save others while they themselves are getting burned out.

2. The "Knowledge vs. Reality" Gap

Here is the twist: The staff actually know what to do.

• They are very smart about heat. 95% know that older people are at high risk. 87% know how to spot the signs of heatstroke (like confusion or dizziness).
• The Problem: Knowing the rules doesn't help if you don't have the tools. It's like a chef knowing exactly how to cook a perfect steak but having no stove, no oven, and a kitchen with no ventilation.

3. The Five "Brakes" Holding Them Back

The researchers asked the staff, "Why can't you just cool things down?" The staff gave five main reasons, which act like heavy brakes on a car:

1. The Money Wall (Funding): Care homes are often running on tight budgets. Installing air conditioning is expensive to buy and even more expensive to run (electricity bills). Some staff said their old AC units are constantly breaking down, costing a fortune to fix.
2. The "Leaky Bucket" Buildings: Many care homes are in very old buildings with poor insulation. It's like trying to keep a room cool with a broken window and thin walls; the heat just seeps right back in.
3. The "Locked Window" Safety Rule: To keep residents safe from falling, many windows have special locks or restrictors that only open a tiny bit. This stops the fresh air from circulating, trapping the hot air inside like a greenhouse.
4. The Treadmill of Work: There aren't enough staff members. When it's hot, everyone needs more water, more checks, and more help moving to cooler spots. But the staff are already stretched thin. They are too busy just keeping up with the daily routine to add extra cooling steps.
5. The "One Size Doesn't Fit All" Problem: Every resident is different. One person might need to be kept cool, while another with poor circulation needs to stay warm. Trying to cool the whole building down might make one resident sick while helping another.

4. What Are They Doing Now?

Since they can't afford big air conditioners, the staff are using "low-tech" solutions:

• Opening windows: But as mentioned, the windows often won't open enough.
• Using fans: But staff noted that if the air outside is already hot, fans are just "blowing hot air around," which doesn't help much.

5. The Solution: A "Swiss Army Knife" Approach

The staff aren't asking for a miracle; they are asking for practical, affordable fixes. They suggested:

• Better Tools: More fans, cooling vests for staff, and maybe some air conditioning in the most important rooms (like dining halls).
• Control: Let the staff on-site turn the thermostats up or down without waiting for permission from a distant office.
• Smarter Schedules: Do the heavy lifting (like bathing residents) early in the morning or late at night when it's cooler.
• Training: More specific training on how to handle heat, not just general care.

The Bottom Line

This paper tells us that while the people taking care of our elderly relatives are knowledgeable and caring, they are fighting a losing battle against the heat because the buildings are old, the money is tight, and the rules are strict.

The Takeaway: As our planet gets hotter, we can't just tell care homes to "try harder." We need to help them upgrade their "ovens" into "cool houses." This means giving them better tools, more flexible rules, and the funding to keep their residents—and the heroes who care for them—safe from the heat.

Technical Summary

1. Problem Statement

Climate change is driving an increase in the frequency and intensity of heatwaves, posing severe health risks to vulnerable populations, particularly older adults in care homes. While the physiological vulnerability of the elderly to heat stress is well-documented, there is a significant knowledge gap regarding the heat resilience of social care settings themselves.

Key issues identified include:

• Occupational Risk: Care home staff face increased physical and cognitive demands during heatwaves, potentially compromising their own health and the quality of care provided.
• Reactive vs. Proactive: Previous research suggests social care practitioners often adopt a reactive approach to extreme heat rather than proactive resilience strategies.
• Infrastructure Deficits: UK care homes often operate in older buildings with poor insulation and restricted ventilation, frequently exceeding the UK Health Security Agency (UKHSA) recommended indoor temperature of 26°C (with some reaching >30°C).
• Implementation Barriers: It remains unclear what specific structural, financial, and organizational barriers prevent staff from implementing effective cooling strategies despite their knowledge of heat risks.

2. Methodology

The study employed a cross-sectional national survey design targeting care home staff across the UK and Ireland.

• Participants: $N = 225$ staff members recruited via convenience sampling from private, state, and charity-funded homes. The cohort included 88 managerial staff (39%) and 137 caregiving staff (61%).
• Data Collection: An online questionnaire (Qualtrics) was distributed between March and September 2025. The survey consisted of 41 items divided into four sections:
  1. Demographics: Role, tenure, home type, and funding source.
  2. Thermal Comfort: Likert-scale assessments of staff and resident comfort, frequency of overheating complaints, and perceived impact on tasks.
  3. Heat Resilience Strategies: Knowledge of guidelines, training received, and implementation of cooling measures (e.g., fans, AC, window opening).
  4. Barriers and Improvements: Open-ended questions regarding obstacles to cooling and suggested improvements.
• Analysis:
  • Quantitative: Descriptive statistics and Mann-Whitney U tests (using SPSS v28.1) to compare responses between managerial and caregiving roles.
  • Qualitative: Inductive thematic analysis (following a 6-step framework) of open-ended responses to identify dominant barriers and improvement strategies.

3. Key Contributions

This study provides the first UK-wide evidence capturing the lived experiences of care home staff regarding heat resilience. Its primary contributions include:

• Dual Perspective: It simultaneously evaluates the impact of heat on both residents and the staff responsible for their care, highlighting that staff are also a vulnerable group.
• Barrier Identification: It moves beyond general awareness to pinpoint specific, actionable barriers (funding, building constraints, staffing) that hinder effective heat management.
• Policy Gap Analysis: It contrasts high levels of staff knowledge with low levels of effective implementation, revealing a "knowledge-action gap" driven by systemic constraints.

4. Key Results

A. Thermal Comfort and Impact

• Prevalence of Overheating: 66% of staff reported feeling "too hot" three or more times per day.
• Impact on Care: 90% of staff felt heat negatively impacted their ability to perform tasks, and 92% believed it compromised resident comfort and health.
• Task Prioritization: Staff ranked medical needs (medication/turning) as the highest priority during heatwaves, followed closely by residents' thermal comfort.
• Satisfaction: While 66% were generally satisfied with their thermal environment, the primary drivers of dissatisfaction were temperature, lack of air movement, and inappropriate clothing.

B. Knowledge and Current Strategies

• High Awareness: 95% of staff recognized older adults' heightened vulnerability, and 87% could identify signs of heat illness. 89% were aware of guidance for protecting residents.
• Current Practices: The most common cooling strategies were opening windows (75%) and using fans (74%).
• Limited Infrastructure: Only 48% had access to air conditioning, and only 39% had control over thermostats.

C. Barriers to Resilience (Thematic Analysis)

Five dominant barriers were identified:

1. Funding Limitations: High costs of installation and energy bills; lack of budget for upgrades.
2. Inadequate Equipment: Lack of AC; fans often ineffective in already hot rooms; old units requiring expensive repairs.
3. Building Constraints: Poor insulation, "oven-like" top floors, and safety restrictors on windows preventing airflow.
4. Staffing Pressures: Shortages and high workloads prevent frequent monitoring and implementation of extra cooling measures.
5. Individual Resident Needs: Mobility issues and sensory needs prevent moving residents to cooler areas or applying cooling measures (e.g., cold flannels).

D. Proposed Improvements

Staff prioritized four areas for improvement:

1. Increased Access to Cooling Equipment: Specifically permanent AC in communal areas and cooling vests.
2. Building Temperature Control: On-site thermostat management and improved ventilation/insulation.
3. Strategy and Policy: Individual heat risk assessments, activity rescheduling to cooler times, and better training.
4. Staff Needs: Cooler uniforms and increased staffing levels during heatwaves.

5. Significance and Implications

• Public Health Policy: The findings underscore that current heat-resilience measures in UK care homes are insufficient and largely reactive. Policy must shift from relying on staff knowledge to addressing structural and financial enablers.
• Operational Recommendations:
  • Low-Cost Interventions: Immediate implementation of low-cost strategies such as rescheduling activities, improving hydration protocols, and allowing flexible window usage where safe.
  • Infrastructure Investment: Long-term necessity for retrofitting older buildings with better insulation and installing accessible cooling systems.
  • Workforce Support: Development of heat-specific training and potential adjustments to shift patterns to mitigate occupational heat stress.
• Future Research: Highlights the need for longitudinal studies on indoor temperatures in care homes and the evaluation of specific cooling interventions (e.g., cooling vests, passive cooling designs) in this specific demographic.

Conclusion: While care home staff possess strong knowledge of heat risks, their ability to protect residents is severely constrained by financial, infrastructural, and staffing limitations. Effective heat resilience requires a systemic approach that integrates affordable cooling technologies, building upgrades, and supportive operational policies.
