At this time, there are many who, for different reasons, end up getting sick, which is not a good taste for anyone. However, sometimes we don’t have a thermometer to check if we have a fever or not, so, despite being able to intuit it, we cannot confirm it.
Today we are going to see a way to check it with our iPhonewithout the need for more devices. It is a very old method that was used many years ago and, despite not being as reliable as a thermometer, it can tell us if we have a high fever, or if we are at a normal temperature.
Check fever with iPhone
To do this, as we said, we will use a very old method, without the need for tools, so we understand that it will not be the same as using a thermometer, logically.
The operation is simple, and it is The human body increases 15 heartbeats for every degree of temperature. extra, that is, if you are a person whose heart rate is around 75 at rest, with a base temperature of 36.5 degrees, if you have a fever of 38, or more, our heart rate would be around 100, indicating that we have or are beginning to have, quite a fever, already over 110 being something to consider.
To calculate them, we can use a manual method, such as our fingers, however, the iPhone has applications that, through the camera and the change in color of the blood in our fingers, can know, exactly, the heart rate we have, for example. so we can use one of these for greater comfort, although if we have an Apple Watch, we will no longer have to install anything, as it will be even more reliable.
As we said, there are many apps, although we leave you one here that has many positive opinions and reliability. Its use, like the rest, is very simple. We will place a finger on the camera, and, using the flash, the app itself will be able to detect when the blood passes, due to the change in color, thus achieving a number of presses at a certain time, offering you the calculation of how many there would be per minute.
It is clear that, for this to work, we will have to know how many heartbeats we usually have at rest, because if more than 100 could be considered a fever, it does not have to be the same for one person as for another, since some have these even when they are well, So it will depend, above all, on the basal degrees we have.
In short, despite being a rare form of check if we have a fevercan serve as an alert, especially if our temperature is 39 degrees, since the pulsations will not deceive us, especially if we are lying down at rest, and we see such a big difference with our normal frequency.
And you, did you know this way? Is there another way that does not require using additional devices? Leave us a comment with your opinion about it, and, if you try it, how reliable it is. I can’t prove it at the moment, as I don’t feel sick, but if you have a fever and a thermometer at hand, you could give us your results using both ways, and find out if it really is that useful.
