How To Preserve The Maximum Dynamic Range In High Contrast Situations
A simple way to know our menstrual cycles is to track our basal temperature, through whose analysis we will know when we have ovulated and if a pregnancy has occurred or, on the contrary, menstruation is about to appear. Although we could use any type of thermometer that we have at home, on the market we have thermometers specially designed for this purpose: basal thermometers .
Thanks to them, we will be able to take our basal temperature with greater comfort and precision, something important if with these data we are going to create a graph, since the temperature variations that are recorded throughout the cycle are small and a deviation could alter our analysis.
What Is A Basal Thermometer For?
A basal thermometer is a thermometer specially manufactured to take our basal temperature: our body temperature as soon as we wake up, when we have had enough rest (of at least four hours) and without moving from bed, just by stretching out the arm to put on the thermometer (any movement could disturb it).
The basal temperature is kept low at the beginning of the cycle to rise once ovulation has occurred, as progesterone (the hormone that dominates ovulation) raises the temperature. If we take our basal temperature properly , we can create a graph, which will allow us to know our fertile days so that we can plan a pregnancy or avoid it. In addition, the elaboration of the graphs during several cycles will help us to better understand our body, being a wonderful self-knowledge tool for women who have irregular cycles.
Why A Basal Thermometer And Not A Normal One?
Given that the changes in basal temperature that we suffer throughout the cycle are only a few tenths, it is important that the thermometer that we use is very accurate. Basal thermometers are specially designed to take the temperature of our body at rest, so that they allow an easier reading, their measurement range is smaller and allows us to specify two or more tenths of temperature.
Types Of Basal Thermometers
Digital basal thermometers have high precision (usually +/- 0.01 ° C), a larger display, and allow temperature recording to two or more tenths.
Glass basal thermometers contain gallium as a substitute for mercury, which was banned due to its high toxicity.
Since they are specially designed for taking our temperature at rest, their measurement range is usually between 35 and 38 ºC, allowing a much easier reading without straining our eyes and with several decimal places.
How To Make And Interpret Our Basal Temperature Graph?
Especially during the first cycles and until we are familiar, we will begin by noting our temperature from the first day of the cycle, which corresponds to the first day of menstruation. When we have more practice we can start around day 5 of the cycle or even later if what we are interested in is only knowing the moment when we ovulate.
We will note not only the recorded temperature but also any other associated symptoms (for example, headache, ovarian pain sensation, etc.), whether or not we have had sexual intercourse and also if any setback has occurred that may have altered it (having stayed up late, being sick, etc).
In Babies and More we offer you a practical example to interpret the table that will surely be useful.
If you do not want to do it on paper, you can make a table in electronic format yourself or use websites that make it easier for you to record and interpret temperatures, such as 28
