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] It can affect any or all anatomical systems. [2]
In patients with multiple sclerosis (MS), heat intolerance may cause a pseudoexacerbation, which is a temporary worsening of MS-related symptoms. A temporary worsening of symptoms can also happen in patients with postural orthostatic tachycardia syndrome (POTS) and dysautonomia. [citation needed]
Increasing heat waves are one effect of climate change that affect human health: Illustration of urban heat exposure via a temperature distribution map: red shows warm areas, white shows hot areas. The effects of heatwaves tend to be more pronounced in urban areas because they are typically warmer than surrounding rural areas due to the urban ...
This increases heat production as respiration is an exothermic reaction in muscle cells. Shivering is more effective than exercise at producing heat because the animal (includes humans) remains still. This means that less heat is lost to the environment through convection. There are two types of shivering: low-intensity and high-intensity.
In the 21st century, those terms are no longer used as medical terminology, deemed an unacceptable, offensive and misleading description of those with Down syndrome. [1] The terminology change was brought about both by scientific and medical experts, [ 2 ] as well as people of Asian ancestry, [ 2 ] including those from Mongolia.
Tick bites are a concern usually associated with summer and hot weather, but experts warn that warmer winters could mean an uptick in ticks and Lyme disease. Warmer winters mean more tick bites ...
With humid heat, the moisture in the air can prevent the evaporation of sweat. [21] Regardless of acclimatization, humid heat poses a far greater threat than dry heat; humans cannot carry out physical outdoor activities at any temperature above 32 °C (90 °F) when the ambient humidity is greater than 95%.
Overall, we found it warm and light; the 650-fill down insulation was in fact able to keep us cozy even in sub-zero climate, and since the construction is pretty much seamless, no heat will escape ...
