The term “going commando” refers to wearing no underwear beneath outer clothing. While often chosen for comfort, this practice has distinct implications for genital health and hygiene. Whether it is beneficial depends heavily on the individual’s anatomy, the type of clothing worn, and the specific circumstances.
Impact on Genital Microclimate and Hygiene
The genital microclimate is characterized by temperature, moisture, and pH balance, all managed by clothing. Traditional underwear, especially tight-fitting or synthetic types, traps heat and moisture against the skin. This warm, damp environment allows opportunistic microorganisms, such as the fungus Candida, to thrive and potentially overgrow.
Forgoing underwear allows for significantly increased airflow and ventilation. This exchange helps the skin stay drier and cooler by facilitating the evaporation of sweat and natural moisture. Non-breathable fabrics can raise skin temperature and increase surface wetness, disrupting the natural, slightly acidic pH. Maximizing ventilation by going commando can help maintain a more balanced environment, potentially reducing the risk of fungal and bacterial issues.
However, lacking an absorbent layer means sweat and discharge transfer directly to outer garments. If these clothes are not washed frequently, they accumulate bacteria and moisture, remaining in direct contact with the genital skin. This direct contact can introduce pathogens, creating hygiene concerns. The benefit of increased airflow must be balanced with the need for clean external clothing to prevent contamination.
Gender-Specific Health Considerations
Anatomical differences result in distinct health considerations when going commando.
Individuals with Vulvas
The primary benefit is the reduction of irritation and prevention of moisture-related infections. Delicate labial tissue is susceptible to chafing and micro-abrasions from the seams and rough fabrics of outer clothing, which are eliminated without an intervening layer. Increased airflow is particularly helpful in reducing the risk of yeast infections and managing bacterial vaginosis by preventing trapped moisture buildup. Conversely, the close proximity of the urethra and anus means direct contact with contaminated outer garments could potentially increase the risk of urinary tract infections (UTIs). Friction from tight clothing without a protective layer may also push bacteria toward the urethra.
Individuals with Penises
Going commando relates to testicular temperature regulation. Sperm production is optimized at a temperature cooler than core body temperature, and tight underwear can raise scrotal temperature. Unrestricted airflow aids in maintaining this cooler temperature, which may support testicular health. Another concern is jock itch (tinea cruris), a fungal infection thriving in warm, moist groin folds. Going without underwear helps keep the area drier, reducing the likelihood of this overgrowth. However, the lack of a supportive layer can increase the risk of painful chafing and friction against outer garment seams, especially during activities involving significant movement.
Situational Context and Garment Choice
The decision to go commando should be influenced by the specific situation and the type of outer garment worn. High-intensity physical activity, such as running or weightlifting, significantly increases sweat production and friction. In these cases, the absence of a moisture-wicking layer may cause the skin to remain wet longer, increasing the risk of chafing, rashes, and fungal infections.
Avoid going commando when wearing outer garments made from rough materials like denim or wool, or those with irritating seams. Constant rubbing of these fabrics against sensitive genital skin can lead to irritation and micro-tears. If outer clothing cannot be washed after every wear (e.g., a suit or trousers), skipping underwear allows moisture and microorganisms to accumulate and remain in contact with the skin.
The practice is safer and more beneficial when wearing loose-fitting, breathable clothing like pajamas, skirts, or sweatpants. The outer garment takes on the role of the primary protective layer. Therefore, these clothes must be made from breathable materials, such as cotton or linen, and laundered after each use to maintain adequate hygiene.
