The Guinness World Record for the longest nose hair belongs to an Indian man named Ram Singh Chauhan. His nose hair measures an astounding 10.1 cm (4 inches) long.
While the world's longest nose hair may seem like a trivial record, it actually highlights the importance of nasal hair. Nose hair helps to filter out dust, pollen, and other irritants from the air we breathe. It also helps to humidify the air and prevent the nasal passages from drying out.
