#8 It Knows If You Have Relations
Most fitness trackers allow you to log certain activities if they are associated with activity, and most trackers let you auto-post your progress and notes to social media. That could be a problem if you have relations – with an increase in activity – and that activity is posted online. In fact that’s exactly what happened to FitBit users in 2011, when users found their sexual activities auto-posting online.
#7 It May Be Harmful to People With Eating Disorders
Fitness trackers can be a blessing and a curse to people who have struggled with eating disorders. On the one hand, it provides confirmation that the person is actively burning calories. On the flip side, it can become a dangerous obsession, fueling a mentality that the person needs to do more. Most experts agree that people with eating disorders should avoid wearable fitness devices.
#6 It Exposes You to EMF Radiation
Your fitness tracker may expose you to unnecessary EMF radiation. Exposure to electromagnetic fields is an unfortunate constant in today’s world of wireless tech devices. However, willingly exposing yourself to 24-hour a day EMF radiation connected to your wrist may be a bad idea, especially when exercising, which allows radiation to enter the body through the sweat glands.
#5 It Leaks Your Personal Data
A study by Citizen Lab and the Munk School of Global Affairs concluded that the apps connected to 8 of the 9 wearables they tested leaked substantial personal information through Bluetooth. All wearables except the Apple Watch allowed third-parties to intercept login information and fabricate fitness information.
#4 It May Expose You to Heavy Metals
The FitBit may expose people to heavy metals. In 2014 the Consumer Product Safety Commission recalled the Fitbit Force due to injuries to 9,900 people. They complained of blisters, peeling skin, rashes and other irritations. FitBit said the injuries were likely a reaction to the nickel alloy in the FitBit.
#3 It Collects Your Personal Data
Senator Chuck Schumer called wearable fitness trackers a “privacy nightmare” due to concerns about how the technology companies stored their consumers’ personal information. Schumer called on the Federal Trade Commission to require the devices to warn consumers that they were collecting valuable health information. Without regulations, your personal information – including identifying traits like how you exercise, what you eat, whether you have medial disorders and even your sleep patterns – could be sold to third parties.
#2 It Becomes Evidence During a Legal Dispute
If you are involved in a legal dispute like a divorce, or are accused of a crime, your wearable fitness device will be seized as a source of evidence. GPS-enabled fitness devices have been used to prove where someone was – or was not – at the time an event occurred. It can also be used during divorce and custody disputes, along with evidence posted to social media about your activities.
#1 It Allows the Government to Track Your Whereabouts
Fitness trackers weren’t on the market very long before several governments realized the potential in the GPS-enabled trackers, namely, that it can keep tabs on your movements. U.S. government agencies are calling this “bio-surveillance” and they have tapped Booz Allen Hamilton, Edward Snowden’s old employer, to develop ways to pull personal information from wearables for use in projects like population mapping. Although the agencies swear the data would only be used for good, skeptics believe the temptation to spy on individuals is too great to resist.
