Abstract		Although most travellers visit places with high external temperatures, severe forms of heat-related illnesses, including heat stroke, are quite rare. Nevertheless, many face symptoms of weakness, irritability, headache, as well as heat oedema, dizziness and even heat exhaustion. Runners, soldiers, elderly and chronically ill persons are more prone to develop heat stroke. The symptoms of high body temperature interfere with the symptoms of dehydration. High body temperature is the result of the imbalance between the production, absorption and dissipation of heat. This could be accompanied with the failure of the temperature control centre. Heat stroke starts at the body core temperatures higher than 40 degrees and is a life-threatening condition. Prompt recognition is crucial and therapy should be started without delay. The cornerstones of successful treatment are immediate energical cooling and rehydration. Preventive care should be consisted of acclimatisation to hot climate, proper clothing, adequate hydration and adjusting of activities to external weather conditions.
Summary		Kljub temu da se večina popotnikov podaja v kraje s povišanimi zunanjimi temperaturami, so skrajne oblike toplotne preobremenitve, kot je vročinska kap, redke. Mnogo se jih sooči s simptomi hitre utrujenosti, razdražljivosti, glavobola, pa tudi vročinskega edema, omedlevice in celo izčrpanosti. Najpogosteje so prizadeti tekači, vojaki, starejše osebe ter kronični bolniki. Simptomi povišane telesne temperature se prepletajo z dehidracijo. Povišanje telesne temperature je rezultat neravnovesja med tvorbo, prejemanjem in oddajanjem toplote, k čimer lahko pripomore tudi odpoved centra za regulacijo telesne temperature. Vročinska kap nastopi pri temperaturah telesnega jedra nad 40 stopinj C in je življenje ogrožujoče stanje. Takega bolnika moramo kar najhitreje prepoznati in nemudoma pričeti z zdravljenjem. Temelja uspešnega zdravljenja sta takojšnje energično hlajenje in rehidracija. Vročinsko kap preprečujemo s prilagoditvijo na vroče podnebje, primernim oblačenjem, zadostnim pitjem tekočine in prilagajanjem aktivnosti zunanjim klimatskim pogojem.
