Myth: Extreme heat is only a concern in tropical countries

Across the United States, heatwaves are becoming a growing concern. Rising temperatures are not only a threat to public health but also a significant economic burden. Cities with high temperatures and low humidity are particularly vulnerable to extreme heat, with cities like Phoenix and Las Vegas experiencing temperatures often reaching 40 degrees Celsius. As a result, the topic of extreme heat is gaining traction, prompting discussions on climate change, heatwave prevention, and heat-related illnesses.

  • Developing new cooling technologies and urban heat island mitigation strategies
  • Heat-related illnesses are a significant risk to human health, especially for vulnerable populations. Heat stress, heat exhaustion, and heatstroke can occur, while long-term exposure to extreme heat can lead to heat acclimatization, which can impact daily activities.

    Is Extreme Heat a New Phenomenon?

    When the temperature reaches 40 degrees Celsius, the human body's ability to regulate its internal temperature is severely compromised. This is due to the way our bodies work: we sweat to cool down, but at extremely high temperatures, sweat evaporation is slowed, making it difficult for our temperatures to drop. This can lead to a range of health issues, including heat exhaustion, heatstroke, and even death.

    No, extreme heat has always been a natural occurrence, but its frequency and severity are increasing due to climate change. The warming of the planet is leading to more frequent and intense heatwaves.

      Risks to Human Health

      • Urban planners and policymakers
      • Opportunities and Realistic Risks

      • Older adults and young children are more susceptible to extreme heat due to their limited ability to regulate their body temperature. Older adults may have impaired heat tolerance due to chronic health conditions, while young children's bodies are still developing and have a harder time regulating temperature.

      • Stay informed about extreme heat forecasts and take necessary precautions to protect yourself and your loved ones. Learn about heatwave prevention and heat-related illnesses to stay safe.

        Our bodies are designed to maintain a consistent internal temperature of 37 degrees Celsius (98.6°F). When we exercise or are exposed to heat, our bodies respond by increasing sweat production. This evaporative process helps to cool us down, but if temperatures are extremely high, sweat evaporation is reduced, causing our body temperature to rise.

        Extreme heat is a vital topic for anyone living in regions frequently affected by heatwaves. This includes:
