In a previous article the Bag Projection Experts explained how to recognize the temperature increase without a thermometer thanks to some symptoms. A separate article, however, deserves the “Liebermeister Rule” which allows you to measure fever with heartbeat when you cannot use the thermometer. In particular, this simple method allows you to evaluate how many degrees your body temperature has risen with a few moves.
The “Liebermeister Rule”
The name of this rule comes from Carl von Liebermeister, a pathologist of German origin who lived in the 19th century. Liebermeister devoted much of his life to studying fever and methods of combating it.
It was he who first discovered the existence of a direct correlation between body temperature and heartbeat. Liebermeister sensed that the tachycardia suffered by those who suffer from a feverish state follows very specific rules. Using this rule today, therefore, it is possible to measure fever with heartbeats without a thermometer.
How to measure fever with heartbeats
According to the “Liebermeister Rule” as the body temperature increases by one degree, the heart rate also increases. This is a difference of about 8/10 beats for each degree.
If the number of resting beats of an individual is known, it is therefore possible to measure by how much the fever has risen. Obviously this method does not offer the guarantees that the use of a thermometer or the measurements made by a doctor provides. However, it can be useful if it is not possible to measure the fever in other ways.
Evaluating your temperature with your heart rate is easy
Two fingers should be placed in those areas of the body where the heartbeat can be heard. Among these stand out the neck, wrist and hollow of the elbow.
Then one has to count how many beats are heard per minute and calculate the difference with the frequency from the healthy individual. However, this method is not foolproof. There are cases when, for example after physical exertion, the heart rate rises in the absence of fever. In addition, some diseases, such as typhus, involve fever but not a rise in temperature.
