A Buyer's Guide to Basal Thermometers

What is a Basal Thermometer?

A basal thermometer is a type of digital thermometer that is specifically designed to measure a person's basal body temperature (BBT). BBT is the lowest body temperature that a person experiences during a 24-hour period and is typically measured first thing in the morning before getting out of bed.

Why Use a Basal Thermometer?

Basal thermometers are often used by women who are trying to conceive to help determine the best time to have intercourse. This is because a woman's BBT increases slightly after ovulation, making it a useful indicator of when ovulation is likely to occur.

In addition to helping with fertility, basal thermometers can also be used to help diagnose certain medical conditions, such as polycystic ovary syndrome (PCOS) and thyroid disorders.

How to Choose a Basal Thermometer

When choosing a basal thermometer, there are a few key factors to consider:

  1. Accuracy: It's important to choose a thermometer that is accurate to within 0.1 degrees Fahrenheit. This will help ensure that you get reliable and consistent readings.

  2. Ease of use: Look for a thermometer that is easy to use and read. Some thermometers have backlit displays and beeps to indicate when the reading is complete, which can be helpful.

  3. Memory function: If you want to track your BBT over time, look for a thermometer that has a memory function that can store multiple readings. This will make it easier to see patterns and identify ovulation.

  4. Additional features: Some basal thermometers come with additional features, such as alarms and data tracking software. These can be helpful if you want to track your BBT over time, but may not be necessary for everyone.

Conclusion

A basal thermometer can be a useful tool for women who are trying to conceive or for those who want to track their BBT for other reasons. By considering factors such as accuracy, ease of use, and additional features, you can choose a basal thermometer that meets your needs and helps you get reliable and consistent readings.

Frequently Asked Questions (FAQs)

1. Do I really need a basal thermometer?

While you can use a regular digital thermometer, a basal thermometer is recommended for tracking tiny changes in body heat. Basal thermometers provide faster and more accurate readings in tenths of a degree, making them ideal for tracking basal body temperature (BBT) changes, which can be helpful for fertility tracking.

2. What is the best basal temperature to get pregnant?

A typical BBT before ovulation is around 97–98°F (36.1–36.6°C). After ovulation, BBT rises by 0.5–1°F on average to 97–98°F (36.1–36.6°C) and remains higher until the end of the menstrual cycle. The most fertile days are usually 2–3 days before the BBT rise.

3. Where do you put a basal thermometer?

You can measure your basal body temperature orally, vaginally, or rectally. Vaginal or rectal measurements generally result in higher temperatures compared to oral measurements. It is important to consistently measure using the same method for accurate tracking.

4. When should I start using a basal thermometer?

Start taking your basal body temperature on the first day of your period and continue measuring every morning until your next period. This helps track changes in BBT throughout your menstrual cycle.

5. Can I use a regular thermometer to track fertility?

Yes, you can use a regular digital thermometer, but a basal thermometer is recommended for tracking fertility. A basal thermometer provides temperature readings in tenths of a degree, allowing for precise tracking of small changes in body heat, which can be beneficial for those trying to conceive or avoid pregnancy.

6. What temperature should you be if fertile?

Before ovulation, a woman's BBT typically ranges between 97°F (36.1°C) and 97.5°F (36.4°C). After ovulation, it rises to 97.6°F (36.4°C) to 98.6°F (37°C). Tracking your BBT every morning can help identify your fertile days.

7. What does BBT look like if pregnant?

A triphasic pattern on your BBT chart may indicate a potential pregnancy, but it is not a guarantee. A triphasic pattern suggests a slight increase in progesterone levels, leading to slightly higher temperatures. However, further pregnancy confirmation is needed.

8. Can I use a forehead thermometer for basal body temperature?

Forehead thermometers are not recommended for tracking basal body temperature. It is best to use a traditional basal thermometer that can be placed under the tongue. Ensure the thermometer measures temperature to two decimal places for accurate tracking of temperature shifts.
