High body temperature is not a disease, yet a symptom which indicates towards a disease or a disturbance raging inside of you. This is usually a response of the organism to virus, bacteria and parasite infection, but it can also happen because of lack of fluids inside the body as well as a reaction to an injection for an example. If you’re wondering about what is normal body temperature the answer is quite simple – this measures in at about 36°C and 37°C. Anything higher than that is usually also followed by headache, shakiness, sweating, loss of appetite and so on.
During the day, normal body temperature tends to be lower during the morning and higher during the afternoon. It is also higher with smaller children than with older people, especially during physical stress and stronger emotions, with women during ovulation and during the first couple of months during pregnancy.
How does one measure body temperature?
Body temperature is measured with a thermometer under the armpit, tongue or rectally. Person who is getting their temperature measured should remain calm and relax. Regardless of the location of measurement, a time period of at least 5 to 10 minutes is expected for a proper measuring, sometimes more for children due to excessive movement. With smallest of children it is recommended to measure the temperature rectally.
Body temperature also depends on the temperature of the surroundings, which is particularly significant with smallest of children. High body temperature is any temperature value measured above 37.2°C under the armpit or 38°C rectally.
Regulation of body temperature
Intensity of body temperature can alternate during the day for a whole 1°C. Body temperature is a consequence of creation of warmth inside the body, which causes it to radiate in the environment. Normal body temperature and reaction of the body towards temperature impulses is regulated by the thermoregulatory center inside the brain, which functions as a thermostat.
Body temperature may also increase due to the disturbed function of the thermoregulatory center, most commonly caused by an infection of a microorganism such as virus or bacteria. This is also affected by all kinds of allergens, tumor protein material, some drugs etc.
As the body temperature rises we know of two phases. In the first phase the organism is trying to rise the body temperature up to the height of thermostatic point. The patient will feel cold, shaky, and pale; he will have cold symptoms and feel generally bad. In the second phase when the body temperature reaches the thermostatic point the patient will feel better, won’t feel cold and the skin will turn hot. This is a time when you need to measure in the temperature, and it’s also a good time to have it forcefully lowered down. The whole point of lowering the body temperature is to reduce subjective difficulties such as headaches, muscle pains and preventing febrific convulsion with smallest of children. All of these factors will help the patient to understand that there is something going on inside the body and that you need to react.
