Devices like the Apple Watch and Samsung Galaxy Watch emit significant levels of EMFs compared to alternatives like the Oura Ring. Here’s a quick comparison of SAR (Specific Absorption Rate) values, which measure how much radiation is absorbed by the body:

• Apple Watch Series 9 (GPS + Cellular): 1.15 W/kg

• Samsung Galaxy Watch 5: 0.64 W/kg

• Oura Ring: 0.0003 W/kg

While all fall below FCC limits, the cumulative exposure from wearing these devices 24/7 is worth reconsidering. Chronic EMF exposure also correlates with hormonal imbalance, particularly reductions in testosterone levels—a critical factor for men’s health. Testosterone not only drives physical performance but also supports mental health and resilience. Men who are exposed to high levels of EMFs may face disruptions in their endocrine systems, affecting energy levels, mood, and muscle retention.

Toxic Chemicals: PFAS in Smartwatch Bands

PFAS, or per- and polyfluoroalkyl substances, are synthetic chemicals found in many smartwatch bands. These “forever chemicals” are prized for their durability and resistance to sweat, but they’re also linked to serious health risks. PFAS exposure can disrupt endocrine function, potentially lowering testosterone levels and impacting male fertility. Long-term exposure is also linked to kidney, liver, and testicular cancers. Alarmingly, research shows up to 60% of certain PFAS compounds can be absorbed through the skin, meaning your smartwatch band might be a direct line for toxins into your bloodstream.

A 2024 University of Notre Dame study revealed that 15 out of 22 tested smartwatch bands contained significant levels of PFAS. Bands made from fluoroelastomers (popular for their durability) were the worst offenders, with PFAS concentrations rivaling those in firefighting gear. Fluoroelastomers are often marketed as hypoallergenic and safe for sensitive skin, but the presence of PFAS negates those claims, introducing significant health risks. Even more troubling is the cumulative nature of PFAS exposure. These chemicals persist in the body over time, accumulating with every daily use of a smartwatch.

PFAS are not just limited to wearable technology. They have infiltrated everyday life, appearing in food packaging, household items, and even water supplies. The smartwatch on your wrist represents only a small fraction of the overall exposure to these harmful chemicals. However, the proximity to the skin—combined with sweat and heat—can accelerate absorption, making it a particularly concerning source.

Breaking News: Apple Watch PFAS 

A new class action lawsuit alleges that some Apple Watch bands—specifically the Sport Band, Ocean Band, and Nike Sport Band—contain potentially harmful levels of PFAS. Filed in the United States District Court of Northern California, the lawsuit claims that Apple’s advertising misleads consumers by portraying the Apple Watch as a health-focused device while failing to disclose the presence of these toxic chemicals.

PFAS, often called “forever chemicals,” are used in manufacturing to make products resistant to sweat, water, and oils. While these properties are convenient, the chemicals are linked to serious health issues, including prostate and kidney cancer, hormone disruption, and pregnancy complications. The lawsuit cites a 2024 University of Notre Dame study, which identified elevated levels of PFAS in these specific Apple Watch bands. It also highlights that these wristbands are worn for extended periods—often 11 or more hours daily—which increases the risk of absorption through the skin.

The plaintiffs argue that Apple knew about the potential risks but chose not to use safer materials, like silicone, in order to cut costs. The lawsuit demands refunds for consumers who purchased the allegedly misleading products and seeks to prohibit Apple from continuing to sell these bands without proper disclosure.

In response, Apple has pushed back, stating: “Apple Watch bands are safe for users to wear. In addition to our own testing, we also work with independent laboratories to conduct rigorous testing and analysis of the materials used in our products.” Apple also pointed to its 2022 commitment to phasing out PFAS and stated that its material safety standards often exceed regulatory requirements.

While the lawsuit targets Apple, it also calls attention to a larger issue within the tech and consumer goods industries. Many manufacturers, including Fitbit and Samsung, also use PFAS in their products. However, some alternatives—like Google’s Pixel Watch Woven Band (made from recycled yarn) and Fitbit’s Sport Band (made from silicone)—may offer PFAS-free options.

This case underscores the need for transparency in wearable technology and raises important questions about the trade-offs between cost, durability, and consumer safety.

The Double Whammy: EMFs and PFAS Combined

What makes wearable tech especially concerning is how EMFs and PFAS may amplify each other’s harmful effects. EMF-induced oxidative stress can reduce your body’s ability to detoxify PFAS and other toxins. EMFs also make it easier for PFAS to penetrate the brain, increasing the risk of neurotoxicity. Both EMFs and PFAS disrupt hormones, creating a compounded effect on testosterone, stress, and energy levels. For men, this double burden is particularly harmful. Reduced testosterone levels can lead to decreased muscle mass, slower recovery, increased fatigue, and even mental health challenges like depression and irritability.

Another area of concern is cardiovascular health. EMFs have been shown to influence heart rate variability (HRV), a key indicator of stress and overall health. When combined with PFAS exposure—which is linked to increased cholesterol levels and arterial plaque buildup—the risks to heart health multiply. Over time, these overlapping effects may significantly compromise overall wellness, particularly for men who prioritize fitness and longevity.

Smarter Ways to Stay Connected

If you’re looking for a health tracker that doesn’t come with constant radiation or toxic materials, the Oura Ring is your best bet. This device focuses on sleep, stress, and activity tracking while emitting minimal EMFs (especially when kept on airplane mode). Unlike smartwatches, it’s designed to monitor your health without trying to be a mini-smartphone. The Oura Ring’s minimalist approach ensures that you get actionable insights without exposing yourself to unnecessary risks.

Aires Tech devices offer advanced EMF protection for those who rely on wearable tech but want added safety. Products like the Lifetune Go and Lifetune Flex neutralize harmful EMF frequencies, helping to reduce oxidative stress and inflammation. These tools provide an extra layer of defense, allowing you to use technology more safely. Aires Tech’s products are particularly useful for men who cannot avoid EMF-heavy environments, such as offices, gyms, or public transportation.
