Basal Body Thermometer Overview

Basal body temperature is pretty much a fancy term given to the lowest possible body temperature at rest which can be measured using a body basal thermometer. In this context, the ideal rest period is during sleeping hours. An estimation of this parameter is usually obtained by measuring the body temperature immediately after sleep and before involvement in any physical activity. See our best basal thermometers review to get the right one for you.

Basal thermometers edge the conventional thermometers in the sense that they provide more accuracy in terms of temperature readings and can handle minor differences, which is a crucial factor when it comes to tracking ovulation. If you look at the temperature difference that comes with ovulation, it’s easy to notice that minute temperature values are involved and it will require an enhanced thermometer for effective monitoring. For instance, basal thermometers can nail a precise reading of 65.42 F instead of a less accurate 65.4 F reading.


Are Basal Thermometers Accurate?

What is a basal thermometer and why is it important? A basal body thermometer is used to get the lowest possible body temperature at rest. It is an ultra-sensitive thermometer designed for natural family planning.  It is the best thermometer for fertility tracking and also the best thermometer for tracking ovulation. Due to the rise in basal body temperature after ovulation, most thermometers are not sensitive enough to pick up this temperature increase. The best basal body temperature thermometers will be able to pick up even the slightest increase in body temperature.

Basal body temperature jumps 0.2 °C or 0.4F and can be read using a BBT thermometer for ovulation. This rise of BBT persists for 3 days when compared to the past 6 days making the estimation of ovulation only valid within the 3 days. This temperature difference is caused by the hormonal changes that occur following the process of ovulation, and to be more specific, the dominance of a hormone called progesterone is the main cause of the difference. These temperature differences are charted over a course of time utilizing the basal thermometer either manually or with the help of a basal thermometer app on mobile devices.

Whether you’re looking to get pregnant or try to avoid it, tracking your body temperature is a big part of natural family planning. It’s not the usual thermometer you used to track fever, but an extra sensitive tool to measure the basal body temperature precisely, even the minutest changes to detect the time of ovulation and fertility.

What Is a Basal Thermometer?

What is a basal thermometer and are the important factors to be considered when buying the best basal thermometer? If you’re trying to conceive, you can use a basal thermometer to track your basal thermometer. This is your temperature when you’re completely at rest. The basal thermometer is more accurate than the traditional thermometer. It also operates within a lower temperature range. Your basal body temperature changes throughout the month based on a variety of factors, including your hormone levels. When you ovulate, your temperature increases with progesterone. Your progesterone levels will remain high during the two-week period between ovulation and menstruation. If you are not pregnant, your progesterone (and basal body temperature) will drop, and menstruate. Your temperature and progesterone levels will remain elevated if you are pregnant.

Having considered the basic terms and mechanisms underlying ovulation and basal body temperature, let’s leap forward and focus on taking your accurate temperature.

[email protected] home Smart BBT Ovulation Thermometer

Basal body temperature (BBT) refers to your body temperature when you wake up before you perform any activity. In addition to changes in luteinizing hormone levels and cervical mucus consistency, women experience changes in their temperature during each menstrual cycle that can be used to indicate ovarian function. In general, women experience a 0.2–0.5 ° C increase in BBT shortly thereafter.

Basal Thermometer Types

There are usually two basic types: a digital basal thermometer that uses batteries and takes up to 60 seconds to measure the temperature. It will have a clear display and will not break easily with careless use. Glass basal thermometer is based on the mercury present, which can be more accurate due to its excellent thermal conductive properties. Since mercury is toxic, it needs to be treated with proper care to protect ourselves while using it.

If your temperature doesn’t go down for at least 18 days after ovulation, you’re probably pregnant. The timeframe that you are most likely to become pregnant is 2-3 days before your body temperature reaches its peak. Typically, it’s the lowest temperature point within 24 hours That’s why, if you’re trying to figure out when you’re most likely to get pregnant, measuring your BBT should be the first thing you do in the morning. Digital Thermometers These thermometers can measure one’s basal body temperature correctly, but rely on mercury. Be sure to compare and consider your options when selecting between mercury and digital thermometers.

Basal Thermometers Give you insight into the Body’s three hormone systems

In the most fundamental sense, the temperature of your body gives insight into how much energy your body produces at rest.

The greater the amount of energy you burn at rest, the more heat your body absorbs, which is expressed in the temperature of your basal body.

What is more fascinating is that your basal body temperature is regulated by many hormones and therefore shows how much energy your body burns.

Be careful if you’re trying to avoid getting pregnant.

This is incredibly important when we talk about weight loss.

And by merely preserving body functions, over 90% of the calories you burn are burned out (breathing, sleeping, eating, thinking, etc.).

Many people (probably you at some point) rely on the amount of calories that are under your control that you burn – meaning the extra calories you burn with exercise.


You only have less than 10 percent of the total amount of calories your body burns per day, even though you triple the number of calories you burn with exercise.

Focusing on your basal body temperature and increasing THAT amount is much safer because it constitutes a far greater fraction of your overall burned calories.

But let’s talk about these hormone systems and how they each alter the body temperature before we get too far into weight loss:

What is Basal Body Temperature, and how does it change over the course of your cycle?

Basal body temperature is the temperature of the body in the resting state, that is when you do not perform any physical or intellectual activity. Typically, it’s the lowest temperature point within 24 hours That’s why, if you’re trying to figure out when you’re most likely to get pregnant, measuring your BBT should be the first thing you do in the morning. Any physical activity, including cuddling with your partner or getting out of bed, is likely to increase your BBT and twist your measurements.

Now, basal body temperature is affected by circadian rhythms, which may change within 24 hours. In women, it is also affected by the menstrual cycle, so there are some monthly fluctuations as well Let’s see how exactly this happens. In the follicular phase of the cycle, which begins on the first day of menstruation and ends on the day of ovulation, estrogen is the dominant hormone in the woman’s body.

During this phase, your BBT remains within the normal range, which is between 97 and 97.7F or 97.7F. This hormone helps make the uterine liner thicker so that the fertilized egg can stick to it. Along with this, the elevated plasma levels of progesterone increase your BBT by 0.4F or 0.2C In women with a normal ovulatory cycle, this shift occurs within 1-2 days and is followed by a period of little or no changes lasting approximately 10 days or up to your next period. Thus, basically, a peak in body temperature and a plateau 2-5 days after this peak will indicate your most fertile days and increase your body temperature.

Choosing the best fertility thermometer begins with a basic understanding of what basal body temperature works and its relationship with the process of ovulation. Along with this is the awareness of the different features associated with basal body thermometers which then empowers you to choose the right gadget for your budget. Having gone through this review, we believe you are aware of all the necessary facts you need to make an informed decision. Thanks for reading the best fertility thermometer review of 2020.

  • How do I clean my basal thermometer?

    A couple days a week, we suggest washing the thermometer. This can be achieved by properly purifying the tip of the thermometer using soap and cold water (or diluted isopropyl).

  • Do basal thermometers really work?

    Although diagrammatizing your basal body temperature (BBT) is a decent way to track ovulation, the low cost is the biggest advantage. A fancy thermometer is unlikely to help you get pregnant quicker. Timing sex for ovulation is the secret to becoming pregnant (if you don't suffer from infertility).

  • Is there a difference between a regular thermometer and a basal thermometer?

    Just as an ordinary thermometer, a basal thermometer tests temperature. The difference is that it calculates to 1/100th of a degree. While most thermometers measure to 1/10 .
