Can a Fitbit be worn in the shower?

No, a Fitbit should not be worn in the shower. While some Fitbits might appear water-resistant, this does not mean they are waterproof or showerproof. Exposing a Fitbit to prolonged contact with water, especially harsh shower water with soap and shampoo residue, can damage the internal components, leading to malfunction or even permanent damage.

Understanding Fitbit Water Resistance Ratings

Understanding the Terminology

Fitbit, like most wearables, uses a water resistance rating to indicate how much water exposure it can handle. It’s crucial to understand the difference between water resistance and waterproofing. Water resistance means the device can handle splashes or brief submersions, while waterproofing means the device is entirely sealed against water. Fitbit devices are never truly waterproof.

Different Water Resistance Ratings

Fitbit uses a system to categorize their water resistance, often denoted by an icon or a number. This rating tells you how much water pressure and duration the device can withstand.

Splash Resistant (most common): This usually means the device is fine with sweat and occasional splashes, but it’s not intended for prolonged or deep water immersion.

Water Resistant (e.g., 5ATM): Indicates a higher level of protection against water, potentially allowing for swimming. However, this usually excludes submersion in anything but shallow bodies of water.

Water-proof (Not applicable to Fitbits): A "waterproof" rating suggests complete sealing of the device, preventing water from entering under any circumstances. Fitbits don’t achieve this level of protection.

It’s essential to check the specific water resistance rating for your Fitbit model. Using a lookup tool or consulting the user manual is strongly advised.

Why Showering with a Fitbit is Risky

Potential Damage

Several factors contribute to the risk of damaging a Fitbit when exposed to shower water:

Water Pressure: Shower water pressure can be forceful, potentially forcing water into crevices and openings that might not be sealed as thoroughly as advertised.

Soap and Shampoo Residues: These substances can penetrate the device’s seals and cause corrosion. They can also leave deposits that interfere with the device’s operation.

Temperature Fluctuations: Sudden changes in water temperature can stress the device’s material.

Contamination: Exposure to harsh tap water can introduce minerals and other impurities that could corrode sensitive components.

Possible Failure Modes

If a Fitbit is worn in a shower, several issues could arise:

Software Glitches or Errors: Water intrusion can cause software glitches and errors, affecting accurate tracking. Data might be corrupted, leading to inaccurate step counts, calorie burn estimations, and sleep data.

Hardware Malfunction: Damage to the internal components can result in a faulty device. This could range from minor intermittent issues to complete device failure.

Electrostatic Discharge (ESD): Especially with hard water, residual mineral deposits can raise the risk of ESD, damaging the device’s electronic components.

Device Damage: Corrosion and water-logged components might lead to cracked lenses, deformation of the case, or short-circuiting.

Alternatives for Shower Tracking

Sweat-Resistant Options for Shower Activity Monitoring

You can achieve fitness tracking in the shower without jeopardizing your Fitbit:

Dedicated Shower Monitors/Smart Scales: There are smart shower scales and activity monitors specifically designed to be used in the shower, which allow you to track your workout data. These devices are typically designed with waterproof functionality.

Fitness trackers designed for water use: Consult other fitness device manufacturers for water-resistant devices.

Wear a waterproof wristband: Using a watch band/bracelet specifically designed for water-resistance might allow more freedom of movement. Consider this as well for swimming activities and/or showering.

Important Considerations:

Consult the Manufacturer: Always check the official documentation for your specific Fitbit model. It provides the most accurate information on what water resistance levels it provides.

Gentle Cleaning and Drying: After any exposure to water, ensure the Fitbit is meticulously cleaned and thoroughly dried using a soft and clean cloth. Do not use harsh chemicals or abrasive cleaners, specifically avoid high-temperature dryers.

Warranty Considerations: Note that wearing a Fitbit in the shower may void any warranties depending on the specific Fitbit product your model has.

Alternative Methods: Utilize smartphone apps or other fitness devices for recording your shower workouts.

Table summarizing Fitbit Water Resistance and Precautions

Rating	Description	Showers? (Recommended)	Explanation
Splash Resistant	Resistant to light splashes.	Generally, yes.	Monitor activity and use caution, and avoid long exposure or high-pressure scenarios within the shower.
Water Resistant (e.g., 5ATM)	More resistant to water; suitable for swimming.	No.	The rating typically only applies to short, shallow swimming and not to showering, which often involves harsher temperatures and residues.
Waterproof	Completely sealed against water; appropriate for high-pressure water exposure.	Yes, but not recommended.	Fitbits need to be water-resistance rated, and they are not water-proof, so submersion is still risky even in the case that it is marketed as waterproof.

In conclusion, while some Fitbits may be water-resistant, they are not designed for extended, high water pressure exposure common in showers. Avoid wearing your Fitbit in the shower to prevent permanent damage to the device. Explore alternative methods for tracking your shower activities.
