We all want to live longer and healthier lives. Exercise is a big part of that. While running is one of the most popular ways to stay fit and active, not all running gear is created equal.
Some accessories you rely on for a better run could harm your health and longevity. This might sound surprising, but it’s true. Certain running accessories can expose you to toxic chemicals and affect your long-term health. From toxic chemicals in clothing to microplastics in water bottles, your choices matter more than you think.
This guide explores four common running accessories that could put your health at risk and how you can make safer, healthier choices.
1. Running Clothes
Running clothes are primarily made from engineered fabrics like polyester, nylon, and spandex. While these fabrics wick sweat and provide stretch, they are often treated with toxic chemicals that can harm your health.
When you sweat, these chemicals can be absorbed into your skin. This can cause dermal issues and other troubles. These polyester fabrics can cause skin issues and allergic reactions.
The biggest concern is PFAS, also known as “forever chemicals,” in many workout clothes. These chemicals help make fabrics stain- and water-resistant but can cause serious health complications.
PFAS chemicals linger forever in your body and are linked to various cancers, hormone disruption, and even developmental issues. To give you an idea of how toxic PFAS is, there’s an ongoing class action against their use, known as the AFFF lawsuit.
TorHoerman Law states that these chemicals were used in the Aqueous Film Forming Foam (AFFF), the primary ingredient in firefighter foam and firefighting gear. Over time, those exposed to the chemical developed life-threatening ailments.
Experts estimate the AFFF lawsuit settlement amounts could exceed billions, with a manufacturer paying over $10 billion in fines earlier this year.
But there’s hope. Consider switching to clothes made from plant filaments like cotton or bamboo. These fabrics are more breathable and less likely to irritate your skin. You can also look for merchants that use safer, more sustainable supplies.
2. Cushioned Running Shoes
Cushioned running shoes promise comfort and shock absorption. However, according to Men’s Fitness, they disrupt your inherent leg biomechanics. Excessive cushioning alters how your feet strike the ground, leading to faulty movement mechanics. Over time, this can weaken muscles, increase joint strain, and cause injuries like shin splints or plantar fasciitis.
A growing body of evidence suggests that zero-drop shoes, which have minimal cushioning, might be a better choice. These shoes mimic barefoot running, improving balance, posture, stride pattern, athletic performance, and natural movement. Moreover, transitioning to minimalist footwear can strengthen your muscles and reduce the risk of injury.
However, the transition should be gradual to avoid sudden strain on unconditioned muscles. Start by wearing zero-drop shoes for short walks or runs, and gradually increase their use to allow your body to adapt. Choosing the right footwear is essential for performance and long-term health.
3. Plastic Sipper Bottles
Staying hydrated during a run is crucial, but plastic sipper bottles may not be the best choice. Most plastic bottles, including those labeled BPA-free, can release microplastics and nanoplastics into your water, especially when exposed to heat or frequent use. These tiny plastic particles are not just destructive to the environment; they also present extreme health risks.
A 2024 research shows that bisphenol A (BPA), often found in plastics, can increase the odds of type 2 diabetes. According to Medical News Today, they do this by reducing peripheral insulin sensitivity. The study further reveals that vulnerable populations like pregnant people and babies are particularly at risk. Additionally, they may disrupt hormone function and contribute to long-term health issues.
Another study reveals a standard-sized water bottle, on average, has over 100,000 plastic molecules. USA Today discloses that 90% of these molecules were nanoplastics while the remaining were microplastics. Nanoplastics are more threatening than microplastics due to their size. They are hard to detect and can invade human cells, causing irreparable damage.
Another similar study reports that over 90% of 259 plastic water bottles from 11 brands were tainted with microplastics. But you can safeguard yourself. Switching to stainless steel or aluminum bottles is a simple yet effective way to reduce exposure to harmful plastics. These materials are safer and more sustainable, protecting your health and the planet.
4. Yoga Mats
That yoga mat you use for post-run stretching might contain harmful chemicals. Many standard mats use toxic materials like PVC, ADA, VOCs, PER, TPE, glues, plasticizers, and latex, which can affect your health. These chemicals release gases that you inhale during floor exercises.
These chemicals are associated with cardiovascular issues and developmental delays in infants. Even high-end brands are guilty of this. A 2022 investigation found that yoga mats from Lululemon contained N-Nitrosodimethylamine (NDMA) over 1,600 times the daily threshold for NDMA exposure per California law. This chemical can cause leukemia, gallbladder, liver, prostate, and stomach cancers.
Prolonged use of such mats can expose you to harmful fumes and particles, especially during hot yoga sessions or intense workouts. This chemical was also discovered in unsafe levels in swimming caps and resistance workout bands. However, in March 2024, the Center for Environmental Health (CEH) signed an agreement with Lululemon, forcing them to make NDMA-free yoga mats.
The good news is safer alternatives exist. Eco-friendly yoga mats made from natural rubber, jute, polymer environmental resin (PER), or cork are non-toxic and biodegradable. They provide the same level of support without exposing you to dangerous chemicals. By making this switch, you prioritize your health and contribute to a more sustainable environment.
People Also Ask
Q1. Are there any other accessories I should be wary of?
Absolutely! Besides the items mentioned, be mindful of things like earbuds, as some contain harmful chemicals in their plastic. Watch for reflective gear (may contain PVC) and sunscreen (look for mineral-based options). Always check the materials and do a little research to make informed choices.
Q2. Are zero-drop shoes suitable for beginners?
Yes, but beginners should transition gradually. Start by using zero-drop shoes for short walks or low-impact activities. This allows your muscles and joints to adapt to the reduced cushioning and natural foot movement. It also minimized the risk of injury during the adjustment period.
Q3. Can eco-friendly running gear match the performance of synthetic materials?
Yes. Eco-friendly running gear has come a long way. Modern sustainable apparel often outperforms traditional synthetics. Merino wool naturally regulates temperature and fights odor. Bamboo fabric offers better moisture-wicking than polyester. Cork-based yoga mats provide superior grip in hot conditions.
Your running routine should be a step toward better health, not a risk to it. By reevaluating your running accessories, you can make safer choices that protect your body and the planet. Start by swapping one accessory at a time. Focus first on items that touch your skin the most, like clothes and yoga mats.
Choose natural materials when possible, and avoid synthetic products with harmful chemicals. Remember, these small but impactful changes can make a big difference in your long-term health. Take these steps today to create a safer running routine for tomorrow. Remember, every decision you make contributes to a healthier, longer life—and a better future for generations to come.
