Tips for using the sensor: You should not eat anything for 2 hours before or after applying it (best in the morning) - this way you will get the best base line reference. You should also not swim or exercise for 2 hours after application - after that, you can shower, swim (no longer than 30 minutes) or exercise. Protect the sensor with kinesiology tape or a patch. It will hold better that way. The FreeStyle Libre 2 sensor needs to be scanned for data transfer (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 water resistant and can be worn in the shower, while swimming, in the sauna and during sports. However, the manufacturer advises against swimming with it for more than 30 minutes or diving deeper than 1 meter.When you sweat, the sensor can fall off more easily, so be careful not to bump it. To be safe, it is recommended that you cover it with a band-aid, physio tape, or patch.Also, remember that you should not remove and reapply the sensor. It is a one-time use device that lasts for 14 days. Once the sensor is removed, it cannot be re-sticked. Please make sure you avoid the following things when wearing the sensor: MR scans (the sensor would need to be removed), vitamin C infusions, and being in water for more than 30 minutes.

No need to worry! It may pinch briefly during the application, but it really does not hurt. We promise. Plus, the needle doesn't stay in your arm, it's just used to insert the filament into your skin, which then measures your blood sugar through the interstitial fluid. You can see how a sensor is attached here.
