health risks as temperatures rise globally. Learn how to protect yourself and loved ones.">
A thorough review of over 40 studies reveals a concerning trend: Older adults consistently underestimate the dangers of extreme heat and are frequently enough ill-equipped to handle prolonged hot weather events. This lack of preparedness creates a critical public health challenge as global temperatures continue to climb.
The Silent Threat of Extreme Heat
Researchers found the majority of existing studies concentrated on immediate responses to heat waves – such as increasing hydration or seeking cooler environments. Though, there’s a noticeable gap in research examining proactive planning for extended periods of high temperatures. This suggests a widespread underestimation of risk among older individuals.
“Extreme heat is not frequently enough viewed as a weather disaster like hurricanes or floods, but it should be. It is not something that is visible, which is why it is often called the ‘silent killer.'”
Smitha Rao, Assistant Professor of Social Work, The Ohio State University
The study, published in PLOS Climate, analyzed data from research conducted worldwide between 2010 and 2024. It highlighted that only a small fraction of studies focused on preparedness measures, emphasizing a significant oversight in protecting a rapidly growing segment of the population.
A Growing Vulnerability
The situation is becoming increasingly urgent. The global population aged 65 and over is expanding rapidly, and projections estimate that by 2050, this age group will outnumber children under five. Together, record-breaking heat waves are becoming more frequent and intense, as evidenced by the extreme temperatures experienced in 2023 and 2024.
“We tend to react based on past experiences in our lives and the reality has changed,” explained Holly Dabelko-Schoeny, a professor of social work at Ohio State. “The things that worked in the past to deal with heat waves are not going to work in this new reality. That goes for those who deliver services to older adults and well as to the individuals themselves.”
The body’s response to heat changes with age, and certain medications or pre-existing medical conditions can further heighten vulnerability to overheating. Many heat-related deaths among older adults occur at home and during the night, indicating a lack of awareness regarding the danger.
A surprising finding was the relative lack of attention given to heat preparedness compared to cold-weather protection. This underscores the need for a shift in public health messaging and resource allocation.
| Area of Focus | Number of Studies | Percentage of Total |
|---|---|---|
| Individual Coping Strategies | 29 | 71.25% |
| Service Delivery | 7 | 17.07% |
| Policy Actions | 5 | 12.20% |
Did You Know? Heat exhaustion can develop quickly, even on moderately warm days.Recognizing the early signs – dizziness, headache, nausea – is crucial for preventing more serious heatstroke.
The Role of Policy and Community Support
Researchers emphasize the importance of proactive policy changes and community-level interventions. These could include weatherizing homes to improve insulation,providing access to affordable cooling options,and establishing accessible cooling centers.
recent initiatives, such as the Central Ohio Transit Authority’s decision to offer free bus rides during extreme heat events, demonstrate a positive step towards ensuring vulnerable populations can access cooling resources.
“It is good to see policy changes like this that are responding to what our new normal looks like,” said Marisa Sheldon, director of the Age-Friendly innovation Centre at Ohio State’s College of Social Work.
Building trust and establishing open communication channels between community agencies and older adults are also vital.This involves understanding individual needs, preferred information sources, and tailoring interventions accordingly.
Pro tip: Stay connected with neighbors, especially those who live alone. A simple check-in during a heat wave can make a life-saving difference.
Long-Term Strategies for Heat Resilience
adapting to rising temperatures requires a multi-faceted approach. Beyond immediate responses, consider:
- Urban Greening: Increasing tree cover and green spaces in cities can significantly reduce the urban heat island effect.
- Building Codes: Updating building codes to prioritize energy efficiency and passive cooling techniques.
- Public Awareness campaigns: Ongoing education efforts to promote heat safety and preparedness.

Silent Danger: How Extreme Heat Threatens Older Adults’ Health and Well-being
Why Older Adults Are More Vulnerable to Heat
as we age, our bodies become less efficient at regulating temperature. This makes older adults notably susceptible to heat exhaustion and heatstroke during periods of extreme heat. Several factors contribute to this increased vulnerability:
Decreased Sweat Gland function: Sweating is the body’s natural cooling mechanism. With age, sweat glands become less active, reducing the ability to effectively cool down.
Chronic Medical Conditions: Conditions like heart disease, diabetes, and obesity can impair the body’s ability to cope with heat stress. Medications commonly used to treat these conditions – diuretics, antihistamines, and beta-blockers, for example – can further exacerbate the problem.
Reduced Thirst Sensation: Older adults often experience a diminished sense of thirst, leading to dehydration, which substantially impacts temperature regulation.
Impaired Circulation: Poor circulation can hinder the body’s ability to redirect blood flow to the skin for cooling.
social Isolation: Living alone or lacking regular social contact can delay recognition of heat-related illness and access to help.
Recognizing the Signs of Heat-Related Illness
Early detection is crucial. Knowing the symptoms of heat exhaustion and heatstroke can save a life.
Heat Exhaustion Symptoms:
heavy sweating
Weakness
Dizziness
Headache
Nausea or vomiting
Muscle cramps
Cool, pale, and clammy skin
Heatstroke Symptoms (a medical emergency):
High body temperature (103°F or higher)
Confusion, altered mental status, or slurred speech
Hot, red, dry or moist skin
Rapid and strong pulse
Loss of consciousness
If you suspect someone is experiencing heatstroke, call emergency services (911 in the US) immediately. while waiting for help, move the person to a cooler location and try to cool them down with cool cloths or a fan.
The Impact of the Urban Heat Island Effect
Urban heat islands – metropolitan areas significantly warmer then surrounding rural areas – pose a heightened risk to older adults. This is due to:
Dark Surfaces: Asphalt and concrete absorb and retain more heat.
Reduced Vegetation: fewer trees and green spaces mean less shade and evaporative cooling.
Waste Heat: Heat generated from buildings, vehicles, and industrial processes contributes to higher temperatures.
Older adults living in cities, particularly those in low-income neighborhoods with limited access to air conditioning and green spaces, are disproportionately affected by the urban heat island effect.
Practical Tips for Staying Cool
Protecting yourself and loved ones from heat waves requires proactive measures.
- Stay Hydrated: drink plenty of fluids throughout the day, even if you don’t feel thirsty. Water is best, but electrolyte-rich beverages can also be helpful. Avoid sugary drinks and alcohol.
- Seek Air Conditioning: Spend time in air-conditioned environments. If you don’t have air conditioning at home, visit cooling centers, libraries, or shopping malls.
- Dress Appropriately: Wear lightweight, loose-fitting, and light-colored clothing.
- Limit Outdoor Activity: Avoid strenuous activities during the hottest part of the day. If you must be outdoors, take frequent breaks in the shade.
- Take Cool Showers or baths: Cooling the body with water can provide temporary relief.
- Check on Neighbors and Family: Regularly check on elderly neighbors, friends, and family members, especially those who live alone.
- Never Leave Anyone in a Parked Car: Car temperatures can rise to dangerous levels within minutes, even on moderately warm days.
the Role of community and Public Health Initiatives
Addressing the threat of extreme heat requires a multi-faceted approach involving community organizations and public health agencies.
Cooling Centers: establishing and promoting accessible cooling centers provides a safe haven for vulnerable populations.
Heat emergency Plans: Developing and implementing heat emergency plans can definitely help communities prepare for and respond to heat waves.
Public Awareness Campaigns: Educating the public about the risks of heat-related illness and how to stay safe is essential.
Home Weatherization Programs: Assisting low-income households with weatherization improvements, such as installing air conditioning or improving insulation, can reduce heat exposure.
* Urban Greening Initiatives: Planting trees and creating green spaces can definitely help mitigate the urban heat island effect.
Case Study: The 2003 European Heat wave
The 2003 European heat wave serves as a stark reminder of the devastating consequences of extreme heat. France was particularly hard hit, with an estimated 14,802 excess deaths attributed to the heat wave.A significant proportion of these deaths occurred among older adults. The event highlighted the importance of preparedness, early warning systems, and coordinated responses to protect vulnerable populations. The lack of adequate social support and the failure to effectively communicate the risks contributed to the high mortality rate.This event spurred significant changes in heat
