Occupational heat stress is the net load to which a worker is exposed from the combined contributions of metabolic heat, environmental factors, and clothing worn, which results in an increase in heat storage in the body. [1] Heat stress can result in heat-related illnesses, such as heat stroke, hyperthermia, heat exhaustion, heat cramps, heat ...
There are three broad pathways by which these effects can take place: directly, indirectly or via awareness. [93] The direct pathway includes stress-related conditions caused by exposure to extreme weather events. These include post-traumatic stress disorder (PTSD). Scientific studies have linked mental health to several climate-related exposures.
Among the staple of WSHC publications are workplace safety and health statistical reports, case studies, guidelines, approved codes of practice, posters, flyers, and videos, and iWSH (newsletter specially designed for workers)).
Heat stroke or heatstroke, also known as sun-stroke, is a severe heat illness that results in a body temperature greater than 40.0 °C (104.0 °F), [4] along with red skin, headache, dizziness, and confusion. [2] Sweating is generally present in exertional heatstroke, but not in classic heatstroke. [5] The start of heat stroke can be sudden or ...

The heat shock response involves a class of stress proteins called heat shock proteins. [ 4 ] [ 5 ] These can help defend a cell against damage by acting as 'chaperons' in protein folding, ensuring that proteins assume their necessary shape and do not become denatured. [ 6 ]
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.
