heat cramps

muscle spasms induced by severe exertion in intense heat, accompanied by considerable pain; sometimes related to salt deficiency, hyperventilation, or overconsumpstion of alcoholic drinks.
Synonym(s): myalgia thermica

heat stress disease

Critical care A group of conditions due to overexposure to or overexertion in excess environmental temperatures
Heat stress-forms in increasing severity
Heat cramps Non-emergent and treated by salt replacement
Heat exhaustion More serious, treated with fluid and salt replacement
Heat stroke Most commonly affecting extremes of ages, especially the elderly, accompanied by convulsions, delusions, coma and treated by cooling the body and replacement of fluids and salts
Note: The body's reaction to heat is a function of controllable–use of anticholinergics, phenothiazines, alcohol, heavy exercise, clothing, obesity, direct exposure and acclimatization and uncontrollable factors–high ambient temperatures or humidity, lack of air circulation, underlying fever, old age or infancy, ectodermal dysplasia

A heat index of 27 to 32 degrees is already deserving of 'caution.' Under these levels, fatigue is possible with prolonged exposure and activity to heat, and continuing activity could result to heat cramps.
Khaleej Times had reported that hospitals in Abu Dhabi were under-reporting cases of heat-related illnesses as in addition to the absence of health coverage, employers also refuse to pay the cost of treatment which could be around Dh1,000 for simple C heat cramps.

Meanwhile, with heat indices between 41 and 54 degrees Celsius, PAGASA said there is impending "danger" as "heat cramps and heat exhaustion are likely" and "heat stroke is probable with continued activity."
On Monday, 14 of Pagasa's 53 weather stations around the country recorded a maximum heat index of at least 41 degrees Celsius, considered the danger level when heat cramps, heat exhaustion and heatstroke are possible with continued activity under the sun.
The state weather bureau considered heat indices of 41[degrees]C to 54[degrees]C as "dangerous," meaning heat cramps and heat exhaustion are likely, and a heat stroke is probable with continued activity."
Pagasa considers a heat index of over 41 degrees Celsius as the danger level, warning of heat cramps, heat exhaustion and probable heat stroke from continued activity under the sun.
A temperature of 32 to 41 degrees Celsius calls for "Extreme Caution" ("heat cramps and heat exhaustion are possible" and "could result in heat stroke"; 41 to 54 degrees Celsiu means "Danger" ("heat cramps and heat exhaustion" and probably "heat stroke"); over 54 degrees Celsius means "Extreme Danger" ("heat stroke imminent")
Pagasa considers it the danger level once the heat index breaches 41 degrees Celsius, warning of heat cramps, heat exhaustion and heat stroke from continued activity under the sun.
With heat indices ranging from 32 to 41 degrees Celsius, PAGASA said "heat cramps and heat exhaustion are possible" and "continuing activity could result to heat stroke."
Pagasa considers it the danger level when the heat index breaches 41 degrees Celsius, warning that continued activity under the sun would likely lead to heat cramps, heat exhaustion and heat stroke.
