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 ...
Physical hazards include ergonomic hazards, radiation, heat and cold stress, vibration hazards, and noise hazards. [1] Engineering controls are often used to mitigate physical hazards. [2] Physical hazards are a common source of injuries in many industries. [3]
During the heat up the surface is relatively hotter and will expand more than the center. An example of this is dental fillings can cause thermal stress in a person's mouth. Sometimes dentists use dental fillings with different thermal expansion coefficients than tooth enamel, the fillings will expand faster than the enamel and cause pain in a ...

Heat syncope, also referred to as exercise-associated collapse, is a moderate form of heat-related illness characterized by a temporary loss of consciousness. Unlike heat exhaustion, heat cramps and heat syncope do not have systemic effects. Heat exhaustion is a precursor to heat stroke, a severe form of heat-related illness.
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]
The heat stress response in plants is mediated by heat shock transcription factors and is well conserved across eukaryotes. HSFs are essential in plants’ ability to both sense and respond to stress. [5] The HSFs, which are divided into three families (A, B, and C), encode the expression of heat shock proteins .
