Global temperatures are steadily rising, with the past decade including 10 of the warmest years on record. As heat waves become more frequent, longer and more intense, experts are increasingly examining how extreme heat affects human health. Rising temperatures can also threaten daily activities, public safety and community well-being.
Extreme heat can place significant stress on the human body. Common heat-related health risks include dehydration, heat exhaustion and heat stroke. Hot weather may also worsen existing medical conditions and increase the risk of cardiovascular problems, including heart attacks and strokes, particularly among older adults, young children and people with underlying health conditions.
The Live Science poll asked readers how concerned they were about the effects of rising temperatures on human health, physical fitness and everyday life. More than 170 people responded to the survey, published on August 26. Of those respondents, 67% said they were “very concerned” about the impact of extreme heat on people around the world.
Readers also shared concerns about the wider effects of climate change. One commenter wrote: “Too many humans fail to realize that the Earth is one living organism. We are all connected. El Niño may start in South America, but its effects will ultimately be felt everywhere. There is only one ocean.”
Another reader described the impact of hot and humid weather on everyday exercise: “I try to take regular walks around my neighborhood, but if it’s too hot—or, more accurately, too humid—I prefer to stay indoors where I can enjoy air-conditioned comfort.”
