Can the letter be written in the shower?

The Redmi Watch 3 Active is waterproof, with a 5ATM water resistance rating. This means it can withstand depths of up to 50 meters and is suitable for use in swimming pools, shallow water activities, and other similar conditions. However, it is not recommended for use in hot showers, saunas, or while diving, and users should avoid direct impact from high-speed water flow during water sports.
