Fact #1. When stricken by the flu or the common cold, it is important to have a thermometer around to monitor you or your loved one's temperature. Usually, there is no cause for major concern. However, if a fever surpasses 103 degrees Fahrenheit or lasts over three days, a visit to a medical facility may be merited. For children, be sure to see a doctor if it is over 102 degrees for more than a full day.
Fact #2. Body temperature is a window into human health. It is an extension of basic body metabolism and a host of other factors. The ideal core temperature is considered to be around 98.6 degrees Fahrenheit or 37 degrees Celsius. But, a perfectly healthy individual's body may be as much as a full degree higher or lower. You should take some readings when you are displaying no signs of illness to know your own personal temperature.
Fact #3. There are many different types of thermometers. It is now uncommon to use actual mercury thermometers. Most of them are now electronic and work very quickly. Place one under your mouth or armpit and it will give you results in seconds. Some are made to take the temperature from the ear. These use infrared technology to give accurate readings. These are less intrusive and can be a good option if you have squirmy children.
Fact #4. If you own pets, thermometers can also be very useful. It can be very difficult to determine whether or not your dog or cat is sick. By accurately measuring their temperature, you can decide whether or not your furry friends need veterinary care.
Fact #5. What can be considered the first modern reliable thermometer was invented by Daniel Gabriel Fahrenheit in 1714. It used mercury instead of alcohol and water mixtures so it was more accurate. He also proposed the temperature scale which now bears his name. Before that, inventors such as Galileo had created rudimentary versions called thermoscopes which had no uniform scale.
