The thermometer is the instrument used to measure the temperature, which is normally between 36.5 and 37.2 ºC. The temperature may vary depending on the ambient temperature, the time it is taken or if there is a disease.
Thermometers have traditionally been made of mercury, but they are toxic to human health and the environment, which is why they are no longer manufactured in Europe. Now, they are made of other materials and digital, easy to use, such as the infrared thermometer , which measures the temperature in the ear.
The body temperature can be measured in the mouth, armpit or rectum, although we should not compare values for different results. Depending on the result, these situations can occur:
- Hypothermia: Below normal temperature (36.5 ºC) when exposed to low temperatures.
- Low-grade fever: Between 37.1 and 37.9 ºC.
- Fever: More than 38 ºC .
