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

• Pain

  She treats several patients each month for asthma attacks, runny noses, muscular pain, flu, pharyngitis, sinusitis, cold, sore throat, muscular aches and severe pains, all mostly the result of air conditioning. [thenational.ae]

  Heat cramps are muscle pains or muscle spasms (usually in the abdomen, arms, or legs) that may occur in association with strenuous activity. [medicinenet.com]

  Painful red or blistering skin and peeling skin (signs of severe sunburn). Onset of sudden cramps either at work or at home. [canada.ca]

  These include: Heat cramps Painful muscle cramps Can lead to heat exhaustion if left untreated Heat exhaustion Shallow breathing Increased heart rate Weak, rapid pulse Cool, pale, clammy skin Sweating Weakness, fatigue, dizziness Headache and nausea Fainting [worksafebc.com]

  Heat cramps - Painful and often incapacitating cramps in muscles. Heat cramps are caused by depletion of salt in the body as a result of heavy sweating, and ingestion of water without replacing salt. [ccohs.ca]

• Fever

  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]

• Chills

  This does not have to be chilled, but if you have a fridge you could also put some tap water in a bottle and chill your own. How about ice creams? Nice try. [theguardian.com]

  The Wind Chill factor is a scale that shows the equivalent temperature given a particular wind speed. [princeton.edu]

  […] exchange with the environment – the body exchanges heat with its surroundings mainly through: radiation - the process by which the body gains heat from surrounding hot objects (e.g. hot metal, furnaces or steam pipes), and loses heat to cold objects (e.g. chilled [worksafe.qld.gov.au]

  Give more frequent but smaller meals, offer chilled food items and minimise hot food. [health.nsw.gov.au]

  Radiation is the process by which the body gains heat from surrounding hot objects, such as hot metal, furnaces or steam pipes, and loses heat to cold objects, such as chilled metallic surfaces, without contact with them. [ccohs.ca]

• Hypothermia

  Therefore, in the present study, we specifically hypothesized that systemic administration of GABA in humans would induce hypothermia in a hot environment and that this response would be observed in association with decreased heat production. [ncbi.nlm.nih.gov]

  Hypothermia : Characterized in the center: Normal body temperature is shown in green, while hypothermic temperature is shown in blue. As can be seen, hypothermia can be conceptualized as a decrease below the thermoregulatory set-point. [en.wikipedia.org]

  If the Cold Challenge is greater than your combined Heat Production and Heat Retention, then you susceptible to a cold illness such as hypothermia or frostbite (see Table 9.3). [princeton.edu]

  Very cold water deals 1d6 points of nonlethal damage from hypothermia per minute of exposure. Drowning Any character can hold her breath for a number of rounds equal to twice her Constitution score. [dandwiki.com]

  A character who takes any nonlethal damage from cold or exposure is beset by frostbite or hypothermia (treat her as fatigued ). These penalties end when the character recovers the nonlethal damage she took from the cold and exposure. [d20pfsrd.com]

• Hypotension

  Orthostatic hypotension after 10 days of exercise-heat acclimation and 28 hours of sleep loss. Aviat Space Environ Med. 2012;83:403–11. [ksi.uconn.edu]

  For example, hypotensives (drugs causing low blood pressure), diuretics, antispasmodics, sedatives, tranquilizers, antidepressants and amphetamines decrease the body's ability to cope with heat. [ccohs.ca]

  Heat syncope (fainting) symptoms: dizziness or lightheadedness and fainting, generally due to prolonged exposure to heat, dehydration, or orthostatic hypotension. [medicinenet.com]

• 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]

• Slurred Speech

  Mental changes: These can include confusion, seizures (particularly in children), delirium, slurred speech, irritability, and coma. Sweat changes: In heatstroke brought on by hot weather, the skin will feel hot and dry. [medicalnewstoday.com]

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]

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]

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]

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

Heat-related illnesses can be prevented. [osha.gov]
