Maintaining personal hygiene is crucial for good health. While most people focus on daily bathing and cleaning their body and hair, there is one part of the body that is often overlooked: the belly button.
Even with regular cleaning, dirt and bacteria can accumulate in this area. According to a 2012 study published in PLOS Onethe belly button harbours 2,368 types of bacteria, with 1,458 species previously unknown to scientists. This area is prone to sweat and is difficult to clean thoroughly due to its shallow structure. As a result, it can emit a foul odour and become a breeding ground for bacteria.
Scientifically, the navel is a scar formed when the umbilical cord is cut after birth. In most people, it is inward, making it more susceptible to accumulating dirt and bacteria. Rarely, an umbilical cord issue may result in an outward navel.
Dermatologists at DLK Cosmetic Dermatology and Laser Clinic in Toronto explain that the navel’s environment is ideal for bacterial growth, particularly for individuals who are overweight, have type 2 diabetes, or have a perforated navel. To clean the navel effectively, use a cloth soaked in warm, soapy water to gently cleanse the area.
Experts warn that if you experience itching, redness, pain, or a foul smell in your navel, it is essential to consult a doctor promptly to prevent infections from worsening.
