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 ...
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 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]
Exertional rhabdomyolysis, the exercise-induced muscle breakdown that results in muscle pain/soreness, is commonly diagnosed using the urine myoglobin test accompanied by high levels of creatine kinase (CK). Myoglobin is the protein released into the bloodstream when skeletal muscle is broken down. The urine test simply examines whether ...
Heat exhaustion is a precursor to heat stroke, a severe form of heat-related illness. Heat stroke is more likely than heat exhaustion to cause pallor, hot and dry skin, syncope, and dysfunction of the central nervous system (e.g., altered mental status, loss of spatial awareness, loss of bodily movement control, seizures, etc.).
Heat stress can result in heat-related illnesses, such as heat stroke, hyperthermia, heat exhaustion, heat cramps, heat rashes, and chronic kidney disease (CKD). [2] [3] Although heat exhaustion is less severe, heat stroke is a medical emergency and requires emergency treatment, which if not provided, can lead to death. [4]
Heat syncope is fainting or dizziness as a result of overheating (syncope is the medical term for fainting). It is a type of heat illness. The basic symptom of heat syncope is fainting, with or without mental confusion. [1] Heat syncope is caused by peripheral vessel dilation, resulting in diminished blood flow to the brain and dehydration.
Of these, some cause isolated attacks of rhabdomyolysis (e.g., dietary deficiency in vitamin E and selenium, poisoning associated with pasture or agricultural poisons such as organophosphates), while others predispose to exertional rhabdomyolysis (e.g., the hereditary condition equine polysaccharide storage myopathy).
