Tight clothing can restrict airflow to the genital area, trapping heat and moisture. This creates a warm, moist environment that can encourage the growth of harmful bacteria and yeast. Persistent use of tight clothing, such as skinny jeans or non-breathable synthetic underwear, can exacerbate these issues, leading to recurrent infections and discomfort. Furthermore, tight clothing can cause friction and irritation, which can result in chafing and other skin issues.
