Can I wear CGM in the Sauna or in the swimming pool?

The FreeStyle Libre 2 sensor is water resistant and can be worn when showering, swimming or in the sauna. The operating temperature is between 50 °F to 113 °F. According to the manufacturer, if the sensor stops working due to extreme temperature, the reader will display an error message. The sensor will resume recording glucose readings once it is within the temperature range again.


To keep the sensor in place, a medical grade adhesive, bandage or tape can be applied over it. The over-bandage must be applied at the time of sensor application and the opening/hole in the center of the sensor must not be covered.
