Dexcom G6 Hot Tub Test: Is It Really Waterproof?


Yes, you can go and wear wearing a Dexcom G6 in a shower, bath, sauna, or any other water-related activities.

The sensor receiver and transmitter have a strong moisture resistance, ensuring accuracy as they won’t be affected by water damage. Additionally, they boast reliable communication and connection capabilities, allowing for seamless data transfer. These devices are also heat-resistant, making them suitable for use in high-temperature environments.

However, it’s important to note that the adhesive patch that comes with the G6 is not waterproof and not moisture-proof and may be prone to damage from exposure to heat and moisture.

So, if you’re planning to soak in hot water for an extended period of time, be aware that heat and moisture can affect the adhesive. Therefore, you may want to use a different adhesive or consult your healthcare provider for other options. It’s also important to note that exposure to water, including showers, can impact the adhesive’s effectiveness.

Can I Wear My Dexcom G6 Sensor In A Hot Tub?

Yes, you can wear your Dexcom sensor device in water, including hot tubs, and shower with the transmitter and patches attached.

However, it is important to keep in mind that water quality is crucial for hot tubs. Installing a sensor device can help monitor the water and ensure it is safe for use.

  • The Dexcom sensor may become less accurate when exposed to temperatures above 100 degrees Fahrenheit. 
  • If the adhesive patch that holds the sensor in place gets wet, it may come off. 
  • If the sensor falls off, be sure to clean it before reattaching it. 

Does Heat Affect The Dexcom G6 Sensor?

There is some anecdotal evidence that suggests that leaving the Dexcom G6 device sensor in a hot place – such as inside a car on a hot day – can affect its performance. Additionally, the transmitter should not be submerged in water or placed in a tub.

However, at this point, there is no scientific evidence to support the claim that water sensor devices can accurately measure the temperature of a hot tub.

The Dexcom G6 sensor device, along with its transmitter, is designed to be worn for seven days and should be kept at room temperature (between 36°F and 96°F). It is important to note that the device should not come in contact with water, sweat or be submerged in a hot tub during this time.

It is not recommended to store the sensor device in a refrigerator or freezer. Additionally, the transmitter should also be kept in a dry area away from water. Avoid the risk by placing either the device or transmitter near a hot tub.

If you do need to protect or store the sensor device for an extended period of time, it should be kept in a cool, dry place away from water. Additionally, if the sensor transmitter is used in a hot tub, extra care should be taken to ensure it is properly stored to prevent any damage.
