Most Fitbit devices are designed to be water-resistant, which means that they can typically withstand exposure to water, allowing for activities such as swimming and showering. However, the level of water resistance varies between models. For example, many devices are rated for swimming in shallow water and can withstand splashes and rain. On the other hand, some models may have a more limited resistance to water exposure. It is important to check the specifications for your specific device model to determine its water resistance rating, which is usually indicated in terms of meters or atmospheres.
Fitbit generally advises users not to wear their devices while diving or engaging in high-velocity water activities. Additionally, while it is possible to shower with a Fitbit device on, it is recommended to avoid exposure to hot water and steam, as it may affect the adhesive that holds the device components together over time. For more detailed and specific information on your particular model, reviewing the Fitbit website is a helpful resource.
