Sometimes a fever is just related to a cold; sometimes, however, it's a symptom of the flu or Covid (here's more on the difference between the flu and Covid). Other times, it could signal ...
Most desert/arid climates receive between 25 and 200 mm (1 and 8 in) of rainfall annually, [2] [3] although some of the most consistently hot areas of Central Australia, the Sahel and Guajira Peninsula can be, due to extreme potential evapotranspiration, classed as arid with the annual rainfall as high as 430 millimetres or 17 inches.
Humans inhabit hot climates, both dry and humid, and have done so for millions of years. Selective use of clothing and technological inventions such as air conditioning allows humans to live in hot climates. One example is the Chaamba, who live in the Sahara Desert. They wear clothing that traps air in between skin and the clothes, preventing ...
The Köppen climate classification is the most widely used climate classification system. [2] It defines a tropical climate as a region where the mean temperature of the coldest month is greater than or equal to 18 °C (64 °F) and does not fit into the criteria for B-group climates, classifying them as an A-group (tropical climate group).

Hot flashes, night sweats, and heat sensitivity can be a sign of hyperthyroidism, hormonal changes, or menopause. Here, experts share potential causes.
The continent mainly lies within the intertropical zone between the Tropic of Cancer and the Tropic of Capricorn, hence its interesting density of humidity. Precipitation intensity is always high, and it is a hot continent. Warm and hot climates prevail all over Africa, but mostly the northern part is marked by aridity and high temperatures.

The efficiency solely depends on the temperature difference between the hot and cold thermal reservoirs. Carnot's theorem states: All irreversible heat engines between two heat reservoirs are less efficient than a Carnot engine operating between the same reservoirs.
