Running is well known for its physical and mental benefits, such as strengthening the legs, enhancing cardiovascular health, and improving cognitive function. However, while logging miles may boost fitness, it can take a toll on your skin. Many runners experience issues such as salt crystals on their face, unexpected sunburns, or painful blisters after a run, raising concerns about whether the skin is suffering from the effects of frequent exercise. These concerns are not uncommon—more than 20 percent of marathon runners report skin problems, and trail runners, in particular, face added risks due to rough terrains.
A recent study published in Quality of Sport by Polish researchers highlights the most frequent skin issues faced by runners and provides guidance on how to address them. Here, we explore how runners can safeguard their skin while enjoying their exercise routine.
Sun Protection: A Vital Measure
Running outdoors exposes your skin to harmful UV rays, making sun protection essential. Research reveals that distance runners, especially marathoners, have an increased risk of developing skin cancer, including both melanoma and non-melanoma types. Interestingly, runners often accumulate more sun exposure over their lifetime than surfers, even though they typically run outside of peak sunlight hours. Sunburn is a frequent issue, particularly for runners under the age of 45.
To protect yourself from sun damage, apply a broad-spectrum sunscreen with an SPF of at least 30 before each run. Wear UV-protective clothing, a hat, and sunglasses to shield vulnerable areas. Runners with lighter skin are at higher risk and should be particularly vigilant. Regularly reapplying sunscreen during longer runs is crucial, as many runners forget this step. For those who sweat heavily, water-resistant sunscreen is recommended, and clothing designed with UV protection can provide added defense.
Is Sweat Bad for Your Skin?
Sweat is a natural cooling mechanism for the body, but it can also contribute to skin problems. The moisture from sweat creates an ideal environment for bacteria to thrive, leading to clogged pores, acne, or skin irritation. Intense exercise, particularly in humid conditions, can also result in heat rashes, commonly known as miliaria.
Despite these potential issues, sweat can benefit your skin by helping flush out toxins. The key is to promptly wash off sweat after your run to prevent irritation and other skin problems.
Friction, Blisters, and Environmental Stress
Runners subject their skin to significant physical stress, including friction, environmental exposure, and potential infections. Blisters are one of the most common skin complaints among runners, typically forming on the feet due to friction between shoes or socks. These fluid-filled, painful spots can be avoided by wearing moisture-wicking socks, using anti-chafing products, and ensuring your shoes fit properly.
Calluses, thickened patches of skin that develop as a defense mechanism against repeated friction, are another common concern for runners. While they can help protect your feet, it is important to differentiate calluses from warts, which may require medical attention. Additionally, runners are prone to fungal infections such as athlete’s foot or fungal nail infections, particularly in warm, sweaty conditions. To prevent these, keep your feet dry, change your socks frequently, and allow your shoes time to air out after each run.
How to Safeguard Your Skin During Runs
While running provides numerous health benefits, it can also present skin-related challenges, from sunburn to blisters caused by friction. Fortunately, these issues can be managed with simple precautions. To keep your skin safe, try to run during cooler parts of the day to reduce sun exposure. Use water-resistant sunscreen, wear moisture-wicking socks, and ensure that your shoes fit well to prevent blisters.
By following these preventive measures, runners can protect their skin and continue to reap the physical and mental benefits of running without the added worry of skin damage.
