Underwear optional? The health pros and cons of going commando

Medical experts and health professionals are highlighting the physiological trade-offs of 'going commando'—the practice of abstaining from wearing underwear—to help the public navigate personal hygiene and comfort. While famously illustrated by Lenny Kravitz’s 2015 wardrobe malfunction in Stockholm where his leather trousers split mid-performance, the decision to skip undergarments is increasingly viewed through a health lens rather than just a fashion statement. Doctors suggest that forgoing underwear can be beneficial in specific contexts, such as reducing moisture buildup that leads to yeast infections or providing relief for those suffering from skin sensitivities and contact dermatitis. From a clinical perspective, the primary benefit of going without underwear is improved air circulation. For women, this can significantly decrease the risk of vulvovaginitis and other infections caused by trapped heat and humidity. For men, some studies suggest that looser environments can help regulate scrotal temperature, potentially aiding in sperm health. However, these benefits are highly dependent on the type of outer clothing being worn; specialists warn that abrasive fabrics like denim or synthetic materials can lead to painful chafing, skin irritation, and even micro-cuts on sensitive genital tissue if there is no protective layer. The context of one's activity also dictates whether undergarments are necessary for hygiene and safety. During high-intensity physical exercise, experts generally recommend moisture-wicking underwear to prevent the accumulation of sweat, which can become a breeding ground for bacteria and fungal growth like tinea cruris, commonly known as jock itch. Conversely, many dermatologists suggest that sleeping without underwear at night is an ideal way to allow the skin to breathe and recover from the day's constriction. Ultimately, the choice to go commando requires a balance between breathability and protection. If choosing to skip the inner layer, individuals are advised to wash their outer clothing—such as trousers or leggings—more frequently, as these garments come into direct contact with bodily fluids and skin flora. Without the barrier provided by underwear, outer garments effectively become the primary layer, necessitating stricter laundering habits to maintain long-term dermatological health and prevent the spread of bacteria.
