Heat is an important environmental and occupational health hazard. Heat stress is the leading cause of weather-related deaths and can exacerbate underlying illnesses including cardiovascular diseas...The number of people exposed to extreme heat is growing exponentially due to climate change in all world regions. Heat-related mortality for people over 65 years of age increased by approximately 8...Between 2000–2019 studies show approximately 489 000 heat-related deaths occur each year, with 45% of these in Asia and 36% in Europe (2). In Europe alone in the summer of 2022, an estimated 61 672...Vulnerability to heat is shaped by both physiological factors, such as age and health status, and exposure factors such as occupation and socio-economic conditions.A heatwave is a period where local excess heat accumulates over a sequence of unusually hot days and nights. Heatwaves and prolonged excess heat conditions are increasing in frequency, duration, intensity and magnitude due to climate change. Even low and moderate intensity heat waves can impact the health and well-being of vulnerable populations. T...
Many populations in tropical and subtropical climates are chronically exposed to high temperatures. In mid to high latitudes, population exposure excess heat is seasonal. Individual vulnerability to heat for physiological or clinical factors in adults is well described (4). Heat can affect health through a variety of direct and indirect mechanisms....
The amount of heat stored in the human body is determined by a combination of (a) an inability to eliminate internally generated heat from metabolic processes due to environmental heat stress (for example, high temperature, high humidity, low wind, high thermal radiation), (b) clothing creating a barrier to heat loss, (c) external heat gain from th...
Stay out of the heat
1. Avoid going outside and doing strenuous activity during the hottest time of day. 2. Stay in the shade. Remember that perceived temperatures in the sun can be 10–15 ˚C higher. 3. Spend 2–3 hours during the day in a cool place. 4. Be aware of the risk of drowning. Never swim alone. 5. Stay informed about official heat warnings.
Keep your home cool
1. Use the night air to cool down your home by opening windows after dark when the outdoor temperature is lower than the indoor temperature. 2. During the day when outdoor temperatures are higher than indoors, close windows and cover them with blinds or shutters to block direct sunlight. Turn off as many electrical devices as possible. 3. Use electric fans only when temperatures are below 40 ˚C / 104 ˚F. In temperatures above 40 ˚C / 104 ˚F, fans will heat the body. 4. If using air conditioni...
Keep your body cool and hydrated
1. Use light and loose-fitting clothing and bed linens. 2. Take cool showers or baths. 3. Wet your skin using a damp cloth, spray, or wet light clothing. 4. Drink water regularly (1 cup of water per hour and at least 2–3 litres per day). 5. Regularly check in with vulnerable people in your circle – especially people over 65 years old and those with heart, lung or kidney conditions, a disability, and living alone.
Mitigating climate change by reducing greenhouse gas emissions is imperative and urgent to limit the magnitude of human costs from extreme heat. WHO is addressing climate change through the Alliance for Transformational Change in Climate and Health (ATACH), as well as country support of technical and policy resources to help the health sector and c...

Heat has been discussed in ordinary language by philosophers. An example is this 1720 quote from John Locke: Heat, is a very brisk agitation of the insensible parts of the object, which produces in us that sensation from whence we denominate the object hot; so what in our sensation is heat, in the object is nothing but motion.
Sep 26, 2024 · The important distinction between heat and temperature (heat being a form of energy and temperature a measure of the amount of that energy present in a body) was clarified during the 18th and 19th centuries.
