Tips for using the sensor: You shouldn't eat anything for 2 hours before or after application (preferably in the morning) – this will provide the best reference. You should also avoid swimming or exercising for 2 hours after application – afterward, you can shower, swim (no longer than 30 minutes), or exercise. Protect the sensor with kinesiology tape or a patch. This will help it stay in place. The FreeStyle Libre 2 sensor must be scanned to transfer data (at least every 8 hours); the FreeStyle Libre 3 sensor transfers data automatically after the first scan. The first data import to the Hello Inside app may take a few hours.

The sensors are waterproof and can be worn in the shower, while swimming, in the sauna, and while exercising. However, the manufacturer recommends not swimming with them for longer than 30 minutes or diving deeper than 1 meter. When you sweat, the sensor may fall off more easily, so be careful not to bump it. To be safe, we recommend covering it with a plaster, physio tape, or patch. Also, remember not to remove and reapply the sensor. This is a single-use device that lasts for 14 days. Once removed, the sensor cannot be reapplied. Please make sure to avoid the following while wearing the sensor: MRI scans (the sensor would need to be removed), vitamin C infusions, and staying in water for more than 30 minutes.

No need to worry! It might pinch a little during use, but it really doesn't hurt. We promise. Furthermore, the needle doesn't stay in your arm; it's used only to insert the thread into your skin, which then measures your blood sugar via the tissue fluid. You can see how a sensor is applied here .
