CONCLUSION: The present study demonstrates that endurance exercise capacity in a hot environment falls progressively as solar radiation increases. [ncbi.nlm.nih.gov]

  Classification [ edit ] Temperature classification Note: The difference between fever and hyperthermia is the underlying mechanism. Different sources have different cut-offs for fever, hyperthermia and hyperpyrexia. [en.wikipedia.org]

  The answer is when the body temperature goes down, we shiver and when it goes up, we know it as fever. As in the example of the car, high temperatures can cause the engine to fail or even burn up; it is about the same for people. [mmgazette.com]

  Many people with MS experience a temporary worsening of their symptoms when the weather is very hot or humid, or when they run a fever. [nationalmssociety.org]

  If your child is sick (fever, vomiting or diarrhoea, or even a mild cold), they need extra attention to ensure they remain well hydrated and don’t overheat. See your doctor if your child is unwell. [health.nsw.gov.au]

• Increased Energy

  The increase in oxygen intake in a hot environment might result from an increased metabolism due to higher body temperature and increased energy requirement for heat dissipation such as profuse sweating, higher heart rate, and increased ventilatory volume [ncbi.nlm.nih.gov]

• Tachycardia

  Heart rate and respiration rate will increase ( tachycardia and tachypnea ) as blood pressure drops and the heart attempts to maintain adequate circulation. [en.wikipedia.org]

• Increased Sweating

  In either case, the positive adaptations that occur include reductions in: Heart rate Body temperature responses Skin temperature responses Perceived exertion As well as increases in: Sweat rate Sweat onset (sweating starts earlier) Heart function/blood [ksi.uconn.edu]

  Convective heat exchange increases with increasing air speed and increased differences between air and skin temperature. Evaporation of sweat from the skin cools the body. [ccohs.ca]

• Flushing

  Heavy sweating, weak pulse, feeling tired, faint, and weak, feeling nauseous, skin is pale or flush, and headaches (signs of heat exhaustion). [canada.ca]

  […] untreated Heat exhaustion Shallow breathing Increased heart rate Weak, rapid pulse Cool, pale, clammy skin Sweating Weakness, fatigue, dizziness Headache and nausea Fainting Muscle cramps Can lead to heat stroke if left untreated Heat stroke Hot, dry, flushed [worksafebc.com]

  Peripheral vasoconstriction (skin gets pale) Pulse Rate - increased Respiratory Rate - increased Urine Output - decreased Temperature - increased (may be over 105° F/41° C) Skin - may be wet or dry, flushed AVPU - Severe changes in mental status and motor [princeton.edu]

• Suggestibility

  The present study suggested that FBF was sufficient for active muscles during IIHG at 10% MVC. [ncbi.nlm.nih.gov]

• Dyslipidemia

  The rate of dyslipidemia was significantly higher in heat-exposed middle-aged workers and in both exposed groups of aged workers (p < .05). [ncbi.nlm.nih.gov]

RESULTS: No statistical differences were noted in temperature between treatments (P>0.05). [ncbi.nlm.nih.gov]

Dizziness and fainting – treatment Treatment for dizziness or fainting includes: Get the person to a cool area and lay them down. If fully conscious, increase fluid intake. [betterhealth.vic.gov.au]

If treatment is not found quickly, heatstroke can be fatal. [medicalnewstoday.com]

"Hyperthermia in Cancer Treatment". Retrieved 2 August 2015. [en.wikipedia.org]

In a hospital, more aggressive cooling measures are available, including intravenous hydration, gastric lavage with iced saline, and even hemodialysis to cool the blood. [8] Epidemiology [ edit ] The frequency of environmental hyperthermia can vary significantly [en.wikipedia.org]

Pathophysiological Aspects. Hyperthermia and the central nervous system (P. Sminia, M.C.C.M. Hulshof). Pathophysiology of brain edema and cell changes following hyperthermic brain injury (H.S. Sharma et al. ). [elsevier.com]

[…] gland tumor, called pheochromocytoma, both of which can cause increased heat production. [8] Damage to the central nervous system, from brain hemorrhage, status epilepticus, and other kinds of injury to the hypothalamus can also cause hyperthermia. [8] Pathophysiology [en.wikipedia.org]

Prevention We can treat heat stress and heat stroke, but the most important is to prevent these situations at work. [futurelearn.com]

In order to prevent such individuals from becoming hyperthermic, we developed a body heat removal system (BHRS) with thermoelectric devices. [ncbi.nlm.nih.gov]

This prevents transpiration in the most exposed leaves, but also prevents growth, hindering the tree in the long term. The second, more drastic way of dealing with drought is to drop leaves, reducing demand. [environment.arlingtonva.us]
