\"\"<\/a>Temperature on the earth\u2019s surface has been rising steadily for at least 140 years. Summer 2024 in the northern hemisphere is especially concerning, with mercury-popping thermostat measurements and record-breaking emergency department admissions. Understanding the impact of extreme heat on human health and implementing strategies to mitigate these risks is crucial \u2013 especially for the world\u2019s most vulnerable people.<\/p>\n

Health Impacts of Extreme Heat<\/strong><\/p>\n

Extreme heat can have both direct and indirect effects on human health. Direct impacts include heat-related illnesses like heat exhaustion and heatstroke. Heat exhaustion is marked by symptoms like heavy sweating, weakness, dizziness, and nausea. Left untreated, it can progress to heatstroke, a life-threatening condition where the body’s temperature regulation fails, leading to rapid heartbeat, confusion, and potential organ damage.<\/p>\n

The elderly, children, and individuals with pre-existing health conditions are particularly vulnerable to extreme heat. Older adults may have less ability to regulate body temperature, while children\u2019s bodies heat up more quickly. People with chronic illnesses such as cardiovascular disease, respiratory conditions, and diabetes also face higher risks during heatwaves. Some medications to treat these conditions can impair thermoregulation or reduce bodily hydration levels, further increasing vulnerability.<\/p>\n

Extreme heat plus air pollutants is especially hazardous, often exacerbating respiratory problems like asthma and chronic lung disease. Mental health issues can also arise, as heatwaves have been associated with increased rates of anxiety, depression, and even aggression.<\/p>\n

\"\"<\/a>Extreme Heat<\/strong> and Vulnerable Communities<\/strong><\/p>\n

Low-income communities often lack access to air conditioning and other cooling resources, making them more susceptible to heat-related illnesses. Additionally, today\u2019s sprawling urban areas, with their heat-absorbing concrete and limited green spaces, tend to experience higher temperatures than rural areas, a phenomenon known as the urban heat island effect.<\/i><\/p>\n

Environmental changes additionally play a role. Deforestation \u2013 whether urban or rural \u2013 reduces natural cooling and prevents the ability of trees to remove heat-absorbing carbon dioxide from the atmosphere. What\u2019s more, access to life-saving safe drinking water is often constrained in the same low-income communities where it is most vital. Finally, some important infectious and contagious diseases are becoming more frequent particularly in low-income heat-strained communities. These include malaria, Dengue fever, Lyme disease, and West Nile virus.<\/p>\n

Personal Mitigation Strategies<\/strong><\/p>\n

While this global phenomenon requires large-scale interventions – especially on the part of public health leaders, urban planners, and engineers \u2013 what can individuals do?<\/p>\n
