Heat stroke is an acute temperature elevation caused by exposure to excessive heat, or combination of heat and humidity, that overwhelms the heat-regulating mechanisms of the body. The latter is a relatively rare side effect of many drugs, particularly those that affect the central nervous system .
Heat shock proteins (HSPs) are a family of proteins produced by cells in response to exposure to stressful conditions. They were first described in relation to heat shock , [ 1 ] but are now known to also be expressed during other stresses including exposure to cold, [ 2 ] UV light [ 3 ] and during wound healing or tissue remodeling.

Most artificial plasmas are generated by the application of electric and/or magnetic fields through a gas. Plasma generated in a laboratory setting and for industrial use can be generally categorized by: The type of power source used to generate the plasma—DC, AC (typically with radio frequency (RF)) and microwave [citation needed]
The start of heat stroke can be sudden or gradual. [3] Heatstroke is a life-threatening condition due to the potential for multi-organ dysfunction, [6] with typical complications including seizures, rhabdomyolysis, or kidney failure. [3] Heat stroke occurs because of high external temperatures and/or physical exertion.
As in other mammals, human thermoregulation is an important aspect of homeostasis. In thermoregulation, body heat is generated mostly in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles. [1] Humans have been able to adapt to a great diversity of climates, including hot humid and hot arid.
Bags of frozen plasma, from a person with hypercholesterolemia (left) and typical plasma (right) Plasma is normally yellow due to bilirubin, carotenoids, hemoglobin, and transferrin. [18] In abnormal cases, plasma can have varying shades of orange, green, or brown. The green color can be due to ceruloplasmin or sulfhemoglobin.
Climate change is making heat waves more intense, potentially leading to a higher risk of heat stroke. The effects of climate change on human health are profound because they increase heat-related illnesses and deaths, respiratory diseases, and the spread of infectious diseases. There is widespread agreement among researchers, health ...
