EMF Radiation Concerns

Fitness trackers like Fitbits rely on a Bluetooth connection which means it emits EMF radiation. And it has to remain connected throughout to enjoy all its features. Bluetooth may have high frequencies & short wavelengths which easily penetrate through the human tissue. So prolonged usage may lead to adverse effects.

Fitness trackers like Fitbits may not cause cancer, but on the other side, the electromagnetic radiation they emit may certainly pose a risk. Short-term exposure to electromagnetic radiation may not lead to cancer but the danger is when you are exposed to electromagnetic radiation for a longer period. Unfortunately, that’s how we use fitness tracking devices like Fitbits.

We tend to wear them on our wrists for quite a long time. At times, some may never remove them after usage too. You should also watch out for any immediate symptoms which could be a warning sign that you are allergic or highly sensitive to EMF radiation which is emitted by the fitness trackers. And this type of illness is known as Electromagnetic Hypersensitivity Syndrome (EHS).

Is It Safe to Sleep with a Fitbit?

One of the features of Fitbit is to track people’s sleeping patterns and provide relevant information. It monitors your heart rate to report about your sleep stages. For this process, users should wear the device the entire night which exposes their body to absorb more EMF.

It can impact the body’s ability to produce melatonin which is responsible for regulating sleep. The production of this hormone is influenced by light. The brain interprets EMF as a form of light and thereby, stops melatonin production.

The body may believe its day time and may not fall asleep. So it is no big surprise if you are unable to fall asleep wearing your Fitbit. It can be a reason for sleepless nights!

EMF Radiation & Skin Ailments

Users also complain about skin rashes after using the fitness device. Skin irritation is said to be one of the most common symptoms of EHS.
