how to use the menstrual skin temperature sensor with samsung health

Your smartwatch can take skin temperature readings while you sleep and relate it to your basal body temperature.

During periods before and after ovulation, basal body temperature increases by approximately 0.3 to 0.5 degrees.

If you use it consistently, your smartwatch can detect the difference in temperatures in the period before and after ovulation, helping to predict ovulation more accurately.

Skin temperature is affected by your surroundings. While you sleep, your skin temperature can vary depending on how you wear your smartwatch, where you’re using it, the clothes you’re wearing, and the ambient temperature.

This is why we recommend that you maintain the most consistent environment possible when taking measurements.

Your skin temperature is measured using an infrared temperature sensor on your Galaxy Watch5 or later.

The sensor automatically measures your skin temperature and shows a daily reading.

Skin temperature and body temperature are two different values, which is why it’s likely that you’ll get two different readings.

Yes, Samsung Health calculates cycle predictions using information about your cycles recorded in the app, without having to measure skin temperature.

Skin temperature can be affected by different environmental factors.

While you sleep, we recommend you always wear your watch on the same wrist, wear the same clothes, and keep the same room temperature. Temperature readings can also be affected by too high or too low temperatures.

If you sleep for less than 4 hours, your skin temperature won’t be properly measured, so make sure to wear your smartwatch for at least four hours while you sleep.

Because your skin temperature is measured while you sleep, the daily representative temperature, which has a strong correlation with basal body temperature, is calculated and used to predict your cycle.

This means that only one representative temperature value is shown each day.

Models before the Galaxy Watch5 series don’t have an integrated infrared skin temperature sensor, so cannot measure skin temperature.

Yes, but for this to happen, you need to activate Predict cycle with skin temperature in Samsung Health.

Your watch will store data from measurements for 28 days, and it will be synchronised when you connect your smartwatch to your phone.

No, skin temperature is automatically measured.

This feature is only for personal reference and is not suitable for contraceptive purposes or medical purposes, such as diagnosis or preventive treatment, as the data may vary from your actual menstrual dates.
 

We also recommend:

• If you are taking medication or receiving treatment to supress ovulation, this feature cannot be used to track your ovulation dates
• We recommend wearing your watch for at least 4 hours while you sleep at night, between 7pm and 9am, at least five times a week. The predicted values can be affected by the way the watch is worn, the values you input, the surrounding environment, etc
• Please do not medically interpret the information provided by this feature or take any medical attention without consulting a qualified medical professional
• This feature is not intended for users under the age of 18

The Predict cycle with skin temperature feature is only available on the Galaxy Watch5 series and upcoming models.

If you’re using a non-Samsung device, the feature will be supported if it has been approved in the country you’re in.
