Cyclists often use cotton in their noses to help filter out dust, pollen, and other allergens while riding, especially in areas with poor air quality. It can also help to keep the nasal passages moist in dry or windy conditions. Additionally, some cyclists believe it provides a slight thermal barrier against cold air, making breathing more comfortable during chilly rides.
