Exposure Levels from Fitness Trackers
Your fitness tracker is constantly emitting electromagnetic radiation to transmit data and connect with your phone or computer. But have you ever wondered how much radiation your tracker is emitting, and whether it’s safe for your body?
Measuring Exposure Levels
Trackers like Fitbit, Garmin, and Apple Watch emit radiofrequency electromagnetic fields (RF EMFs) to communicate with nearby devices. To measure the exposure levels, scientists use a unit called the specific absorption rate (SAR), which represents the amount of RF energy absorbed by the body when using a device. In the case of fitness trackers, the SAR values are usually measured at the wrist, where the device is worn.
Studies have shown that the SAR values for popular fitness trackers range from 0.18 to 0.93 watts per kilogram (W/kg). For comparison, the Federal Communications Commission (FCC) sets a safety limit of 1.6 W/kg for RF exposure from wireless devices. This means that most fitness trackers emit radiation well below the safety limit.
Comparing Exposure Levels to Other Devices
Exposure Levels from Common Devices
| Device | SAR Value (W/kg) |
|---|---|
| Fitness Tracker (e.g., Fitbit) | 0.18-0.93 |
