Changes in Temperature

Patients, children, adults, animals, etc. need their temperatures taken regularly when sick to determine fever and illness. Glass mercury thermometers, developed in 1714, were once the most popular way of reading body temperatures. They may still be considered the most accurate thermometer because they are glass and do contain mercury; however, they have now been found to have a dangerous risk. Glass thermometers have a risk of being broken and causing external and internal injuries of the mouth, rectum, etc. It also exposes the person to mercury which can be poisonous and fatal. Many people do not understand the dangers of glass thermometers because they were once the only thing used to take temperatures in the past. Glass mercury thermometers are no longer sold in stores because of the new, safer ones that are now used.
