What should be the temperature of the body?
Many people are interested in the question, what should beBody temperature? Let's try to figure it out. The optimal temperature in the oral cavity is from 36-37.8 ° C. If it is not possible to measure the temperature in the oral cavity, then it is necessary to perform a measurement in the auditory canal, rectum or in the armpits.
Everyone knows that the normal body temperature is subject to slight fluctuations in the morning and evening. The temperature can also depend on the individual characteristics of the body.
Basal temperature measurement is performeddaily at the same time in the rectum to determine ovulation. It is recommended to measure this temperature in the morning hours, immediately after awakening for 10 minutes, without getting out of bed.
Critical temperature
Fever or temperature rise usuallyaccompanied by chills, excessive sweating, weakness and arthralgia. A rise in temperature above 41 ° C is considered critical and can lead to neuralgic disorders or even death.
In elderly people with chronic diseases, especially pulmonary, cardiovascular or central nervous system pathology, a sudden increase in temperature can lead to impaired consciousness.
Physiological aspect
While maintaining the temperature in the bodyan important role is played by the center of thermoregulation, which is located next to the bottom of the third ventricle in the hypothalamus. It reacts to polypeptides, namely cytokines and pyrogen, which in turn react to various bacteria and viruses.
In the hypothalamus under their action occursactivation of phospholipases, resulting in the production of an arachidic acid. Further, prostalin E2 formed from it provokes an increase in the temperature setting in the hypothalamus. Tablets with antipyretic activity inhibit the activity of cycloxygenase and the synthesis of prostaglandins.
