Hoe vind warmteafgifte plaats?

De warmteafgifte aan de omgeving vindt plaats op 4 manieren: afgifte aan de lucht rondom het lichaam, afgifte aan materialen tegen het lichaam (geleiding), straling en verdamping van zweet. In een warme omgeving worden de eerste drie mechanismen minder effectief.

Het lichaam produceert zweet, dat op de huid verdampt. Verdamping van het zweet onttrekt warmte aan het lichaam. De warmte-afgifte gaat dus niet door het zweten zelf, maar juist door de verdamping van het zweet. Daarom is naast de temperatuur ook de luchtvochtigheid van belang voor de warmte-afgifte.

What is the normal range of rectal temperature?

A rectal temperature is 0.5°F (0.3°C) to 1°F (0.6°C) higher than an oral temperature. An ear (tympanic) temperature is 0.5°F (0.3°C) to 1°F (0.6°C) higher than an oral temperature. An armpit (axillary) temperature is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.

What does it mean when your body temperature is 103?

A fever is one way your body fights illness—your body temperature goes up to kill bacteria that cannot live at the higher temperatures. Although it may not be comfortable, a temperature of up to 102°F is generally good for you. Most healthy adults can tolerate a fever as high as 103°F…
