Typically used for pregnancy tests, a basal thermometer is usually a more accurate device than a regular thermometer. It was designed specifically to measure the ovulation period of a woman, which is characterized by the rise in temperature of their bodies. In this article, we will find out more about basal thermometers and how they can help you as an expectant mom or if you want to know whether you’re bound to be pregnant or not.
What is the difference between a basal thermometer and a normal one?
Here are the known differences between the two types of thermometers:
1. What are they mainly used for?
Normal thermometer: the regular thermometer is used for general check-ups, as well as knowing if a person has a fever, flu, or a significant change in their body heat or temperature. They have an average amount of accuracy and they tend to be used more often.
Basal thermometer: a basal thermometer is less likely to be found on a regular medicine cabinet since it’s not very much used as compared to a regular thermometer. It can read even the slightest change in temperature, which makes it ideal for women who want to find out if they will likely get a period on a certain time period or not. Thus, it can be used by couples who are trying to make a baby.
Most women use a basal thermometer or the BBT (basal body temperature) method for the following reasons:
- Determining fertile days. Knowing which days of the month you are most fertile will help you and your partner in conceiving a baby, which is ideal for the newlyweds. It may not be the most accurate method when used alone, if you use it with other methods of family planning, it can really help to get you pregnant soon enough, since you will know what days to have sex with your partner.
- Track down menstruation. For women who seem to have irregular menstruation or for those who are just curious, they can also know their menstrual period or cycle better if they use the BBT method in the morning. Knowing the menstrual cycle could also help you to keep track as to whether you need to shop immediately for tampons or napkins and pack them in your tote bag.
- Look for any hormonal imbalance. In some cases, the BBT method could also reveal if there are any hormonal imbalances since the hormones are at work when your temperature goes up and down during the ovulation period.
- Avoid getting pregnant. While it can be used to get pregnant, some teens and women do want to avoid getting pregnant, so they can use the BBT method as a supporting way (not to be used alone) to find out if they will likely get pregnant on a certain period in the calendar.
2. How accurate are they?
Normal thermometer: the accuracy of a regular thermometer is only about 0.2 degrees Fahrenheit, which is pretty average compared to that of the basal thermometer.
Basal thermometer: it has an accuracy of about 0.1 degrees Fahrenheit, which means that it can be a more accurate measurement of your body temperature as compared to a regular thermometer. After all, the ovulation period of a woman can have very small changes in temperature.
3. How are they typically used?
Normal thermometer: you can use a regular thermometer for oral, anal, and armpit methods, simply because they are just meant to track a person’s flu or fever based on their body temperature.
Basal thermometer: it can be used in the same way as the normal thermometer, except that since it is a basal thermometer that is mainly used by women, some women even consider vaginal use for added accuracy.
The basal thermometer does have a few similarities with the regular thermometer, such as the different types of thermometers:
1. Mercury-based: this is the most traditional and basic of all thermometers. They are preferred by traditional practitioners because they have been around for a long time. The mercury inside the thermometer can increase or decrease depending on the temperature of the body. You place the metal part of the thermometer in the specified area (e.g. armpits) to get a temperature reading. Most countries have started phasing out mercury thermometers due to the ill effects of mercury when it gets out of the tube.
2. Digital thermometer: the digital thermometer is quite accurate and fast, up to 60 seconds, so they could be more preferred by modern practitioners. The only downside is that they need batteries as compared to mercury thermometers.
Can you use a normal thermometer for basal?
You can, but it will not be as accurate as you think. This is because the basal thermometer has an accuracy of about 0.1 degrees Fahrenheit, as compared to the normal thermometer, which has only about 0.2 degrees Fahrenheit. This can mean a significant difference between the two as with measuring and determining your ovulation period.
How do you check your basal body temperature for ovulation?
BBT or basal body temperature is a quick method for women (or couples) to know the best time for getting pregnant, which is during their ovulation period. Here’s how to find it out using a basal thermometer:
1. Have your basal thermometer beside you before you go to bed for easy access. Get at least 3 hours of sleep before you do take your body temperature the next day.
2. Measure your basal body temperature right away when you wake up in the morning (do not get out of bed or do anything else).
3. Repeat for up to 3 cycles and log them into your notebook or BBT-keeping mobile app.
Here are important notes with tracking BBT:
1. Make sure you measure with one thermometer only and don’t use others to ensure that there’s an accurate and constant temperature reading.
2. If you measure in a certain way (vaginally, orally, or rectally), do not measure in any other way to ensure constant temperature reading that’s more accurate.
What is the best basal temperature to get pregnant?
The typical temperature of the ovulation period is characterized by a sharp rise in the body temperature, which can be from 36 that goes up to 37 degrees but in points. To help you determine that, here are our top picks for the best basal thermometer:
