Can You Wear a Fitbit in the Pool?

Fitbits are designed to be water-resistant up to 50 meters. So you can wear them in the pool without damaging the device. Some of the Fitbit models you can swim with include Ionic, Inspire, Charge 3, Versa, and Ace 2. Make sure to dry the device once you’re out of the swimming pool.

Most Fitbit devices are swim-proof and can withstand even the sweatiest workouts in the gym. However, check the manual to see if the specific model you are wearing is only splashproof or completely swim-proof. Additionally, not all accessory bands can be worn while swimming, such as those made of woven, metal, and leather materials.

The following are the Fitbit devices that have a water resistance rating of 50 meters:

  • Versa series
  • Sense
  • Luxe
  • Ionic
  • Inspire series
  • Flex 2
  • Charge 3 to 5
  • Ace 2 and 3

On the other hand, Fitbit Ace is only showerproof, which means you can’t wear it while swimming because it’s only designed to resist spills and splashes.

Over time, water resistance will decrease and may get affected by exposure to high-velocity water, such as water sports, and exposure to harsh chemicals including sunscreen, lotions, insect repellent, perfume, conditioners, shampoos, and soaps.

If your Fitbit gets wet, take the device off and dry it completely before wearing it again. If the device gets wet by other liquids, it’s important to clean it using water and any soap-free cleanser, dry it using a soft cloth.

No matter if your Fitbits are water resistant, don’t expect them to last as long, if you go go swimming with them everyday or even worse in the ocean. Discover how long your Fitbit should last under normal use in my helpful article.Opens in a new tab.

Can Fitbit Handle Heat?

According to Fitbits user manual most Fitbits ares designed to operate in temperatures up to 113°F(45°C), any hotter and the Fitbit will likely suffer damage.

Extreme heat may cause the device to turn off as it drains the battery much faster than under mild temperatures. I would not recommend wearing your Fitbit in the sauna because it may affect its overall performance.

More importantly, do not expose your device to direct sunlight for a long period of time as it can damage the color and appearance while affecting the internal components.

The safety manual lets you see the exact temperature range that your Fitbit model can withstand. If you’re not sure, contact the support team to know the actual temperature your device can handle in terms of heat level.

One big issue smartwatches have, is they use green light sensors to track your heat rate, that isn’t as effective on darker skin, to know if you can watch Fitbit with your skin colour please read my helpful article.Opens in a new tab.
