Smartwatches have become an everyday part of our lives, helping us track activity, health and time, but do we really know everything about them? Recent research suggests that the dangers of smartwatches may lie in their straps. Harmful substances such as polyfluoroalkyl substances (PFAS) found in some thongs can have negative health effects. The study was published in the journal Environmental Science & Technology Letters.
According to physicist Gray F. Pease of the University of Notre Dame Maryland (USA), scientists did not expect that smartwatch straps made with polyfluoroalkyl substances (PFAS) are so widespread. These substances are found in fluoroelastomer, a special material used in the manufacture of accessories for various devices.
It has been discovered that fluoroelastomers can contain perfluorohexanoic acid (PFHxA), commonly referred to as the “forever chemical”. This material is non-biodegradable and resistant to light and water. was found in most of the 22 smartwatch and fitness band straps tested.
Polyfluoroalkyl substances (PFAS) have been linked to cancer risk, high blood pressure and infertility, according to the study. Nevertheless, they are widely used in the production of non-glare dishes, umbrellas, cosmetics, furniture, cleaning products and waterproof fabrics.
The researchers emphasized that consumers often underestimate the potential dangers caused by skin contact with hazardous substances contained in the straps of smart devices. However, the researchers note that there is a solution: usually, the strap of any brand of smartwatch can be replaced with an alternative made of a neutral and safer material.
