Heat illness is a spectrum of disorders due to increased body temperature. It can be caused by either environmental conditions or by exertion.It includes minor conditions such as heat cramps, heat syncope, and heat exhaustion as well as the more severe condition known as heat stroke. [1]
The main danger with a heat wave is probably obvious: too much time spent in the heat can quickly lead to illnesses such as heat exhaustion or heat stroke, which could prove fatal.
Hyperthermia, also known simply as overheating, is a condition in which an individual's body temperature is elevated beyond normal due to failed thermoregulation.The person's body produces or absorbs more heat than it dissipates.
Japan's government and Fire and Disaster Management Agency responded to the ongoing excessive heat by issuing more health advisory notices to the public on 19 July. The Fire and Disaster Management Agency's official weekly statistics for 19 July showed 8,189 (4,484 were 65 or over) were hospitalized that week, up 200% compared to the previous ...
The combined effects of shifting land use and climate change mean extreme wildfires are projected to become more frequent and intense globally, according to the UN Environment Programme (UNEP).
Heat syncope, also referred to as exercise-associated collapse, is a moderate form of heat-related illness characterized by a temporary loss of consciousness. Unlike heat exhaustion, heat cramps and heat syncope do not have systemic effects. Heat exhaustion is a precursor to heat stroke, a severe form of heat-related illness.
Heatwaves over land have become more frequent and more intense in almost all world regions since the 1950s, due to climate change. Heat waves are more likely to occur simultaneously with droughts. Marine heatwaves are twice as likely as they were in 1980. [34] Climate change will lead to more very hot days and fewer very cold days.
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
