Selecting the Best Basal Thermometer for Your Health

A basal thermometer is a helpful tool that any woman should have for trying to conceive or just monitoring your cycle. This thermometer can help you determine when you are ovulating to increase your chances of conceiving.

It is important to have a basal thermometer that is very accurate, because just a percentage point difference in the reading can indicate whether or not you are ovulating.

In this article, we’ll cover how to choose the best basal thermometer and everything you should know, as well as review the best basal thermometers on the market.

What is a Basal Thermometer and How Do I Use It?

Your basal body temperature is the lowest body temperature you attain during sleep or relaxation periods. This temperature is controlled by your hormones (as well as some other factors), and it can be indicative of whether or not you are ovulating.

A basal thermometer takes your basal body temperature. You can take your basal body temperature either orally or vaginally. 

  • Your vaginal temperature tends to be more accurate when it comes to monitoring your cycle, but you can still get good results by taking your temperature orally.

When using a basal thermometer to monitor your cycle, you should get into the habit of taking your temperature right before you get out of bed in the morning.

  • This is when your basal body temperature is most accurate

Any activity, even just walking to the bathroom, can raise your basal body temperature and reduce the accuracy of the reading. You’ll need to take your temperature every day to get a consistent reading.

Your temperature will be roughly the same every day when you are not ovulating, but when you are ovulating, you will notice an increase of .4 to .6 in your basal body temperature.

This means that you are ovulating and that it is an ideal time to try to conceive

Over several cycles, you’ll learn what is normal for your body, and you’ll be able to get the most accurate results.

Generally, your body will have a basal temperature of around 96 to 98 percent during the first two weeks of your cycle, before ovulation occurs.

The change in body temperature happens just before you will start to ovulate. Everyone’s body changes are different, which is why it is is important for you to continually monitor your own changes to learn what is normal.

In addition to using this strategy to conceive, some women use it as a backup form of birth control. However, it is not as effective for birth control as other methods, so it’s still ideal to use condoms if you are trying to prevent pregnancy.

Many women find that they feel more empowered and in touch with their bodies when monitoring their cycles.

What Should I Look For in a Basal Thermometer?

There are several things you should look for in a basal thermometer.

GLASS OR DIGITAL

The first thing to consider is whether you want a glass or digital thermometer. Digital thermometers have tons of perks - they’re easier to read, they let you know exactly how long to leave the thermometer in, and they’re less fragile. However, glass thermometers are often less expensive.

ACCURACY

The next thing to consider is of course, the accuracy of the thermometer. For the thermometer to be accurate, it needs to measure to the tenth of a degree for Fahrenheit and to the hundredth of a degree for Celcius.

This allows you to get the most accurate results when it comes to charting your ovulation.

EASIER TO USE

Beyond those two important features, you should look for features that make the thermometer easier to use. The easier it is for you to take your temperature in the morning, the more likely you will be to monitor it consistently.

A very helpful feature that many thermometers have is a beep that tells you how long to leave it in. This ensures that you get a very accurate temperature reading.

  • Generally, you’ll need to leave the thermometer in for about 30 seconds to get the most accurate temperature.

Some thermometers are able to capture an accurate temperature faster, which can be a plus.

However, you should be wary of any thermometer that says it can capture an accurate temperature after just one or two seconds, as this is very difficult to do.

DISPLAY

You’ll also want to consider the quality of the display. It should be large and easy to read, and it should also be easy to turn the thermometer on and off.

The thermometer should also remember the last temperature taken so you can chart the difference between the results each day.

Some digital thermometers even sync with an app on your phone, which makes it even easier to keep an accurate record of your temperature each day.

COMFORTABLE

Comfort is also a very important factor to consider when looking for thermometers. Since you will be using it very frequently, you’ll want to make sure that taking your temperature is not uncomfortable or painful.

A thin thermometer is generally the most comfortable to use. You’ll also want to avoid anything that has sharp edges.

Any additional features that make the thermometer easier to use are also very valuable and often worth paying a bit extra for.

For example: 

some thermometers have features such as a backlight, extended memory, and more. This is a good investment, because the easier it is to take your basal body temperature, the more likely you will be to accurately track your fertility.​

This thermometer is extremely accurate, and it is designed to capture changes in your body temperature to up to a hundredth of a degree.

It takes up to a full minute to capture your temperature, but the longer measurement time actually gives better results.

In fact, it is so accurate that it can be used orally and will provide similar accuracy to a vaginal measurement.

The temperature also remains on the display until you manually turn it off, so you can take the time to record your temperature. It is very durable and comes in a plastic case for storage.

The only downside is that it can be a little difficult to see what you are doing if your bedroom is dark, because there is no backlight
