Is My Sensor Waterproof? Swimming and Hot Tub Guidelines

Yes, your sensor is waterproof up to 8 feet, so you can wear it while swimming or in a hot tub. However, there are a few important considerations:

1. Temperature Guidelines

• Continuous Glucose Monitors (CGMs) operate best between 50°F and 113°F (10°C to 45°C).

• Exposing the sensor to temperatures outside this range—such as in saunas, hot tubs, hot yoga, or ice baths—may cause temporary sensor errors.

• If this happens, your sensor will typically recover on its own once your body returns to a normal temperature range.

2. Glucose Reading Variations

• Extreme temperatures can affect your body temperature and glucose metabolism, which may cause unusual glucose readings during or shortly after exposure.

• This doesn't mean the sensor is malfunctioning—it’s your body’s natural response to heat or cold.

3. Swimming and Bathing

• Normal swimming, showering, and bathing are generally fine and do not impact sensor function, as long as you're within the recommended temperature range and the sensor is well-secured.
