Heat exhaustion and heatstroke As days slowly begin to heat up it is important to stay cool and keep hydrated across the screaming scorching sun. Summer time usually means longer days and if you live close to the equator you know about the 100+ degree weather that comes with it. Without the proper precautions you could easily fall to heat exhaustion or far worse a heat stroke. Athletes are more prone to this type of sudden illnesses because of the constant running and exercise they do on a daily

Research Summary Heat stroke is defined by Knochel and Ouchama (2002‚ p. 1978) as “a core body temperature that rises above 40°C (105°F) and that is accompanied by hot‚ dry skin and central nervous system abnormalities such as delirium‚ convulsions‚ or coma.” Heat stroke can be the result of either exposure to a high environmental temperature or from an elevated core temperature due to strenuous exercise. However‚ due to the presentation of an ‘unconscious unknown’ the diagnosis of heat stroke can be

Swine Heat Stress ABSTRACT The purpose of this research project is to identify the effects of heat stress on swine. Heat stress is physiological distress caused by excessive temperatures usually over 80-85 degrees Fahrenheit that can result in profoundly adverse effects in swine production. The first phase of this project involves the analysis of these harmful effects on sows‚ gilts‚ and boars. Multiple journal articles will be used to establish these effects. The final phase involves

August Heat Suspense can make you over think and become attentive. The feeling of wanting to know more creates confusions and boldness to the reader. The reason for suspense is to hook the reader onto the story‚ while hooking the reader to the story‚ the author wants to astound the reader into wanting more. W.F Harvey introduces suspense and it is shown throughout the story “August Heat” but it’s enhanced in the ending of the story. The story is about two men who occasionally meet one hot summer
