Health experts are warning that using headphones, especially in-ear earbuds, can increase the risk of ear infections, particularly when shared or used during illness. A 2025 study found that headphone use is linked to a greater risk of ear infections, as blocked ear canals become hotter and more humid, creating an ideal environment for harmful microbes.
The ear canal naturally hosts a range of non-harmful bacteria, fungi, and viruses that help prevent infections. However, wearing headphones for extended periods can upset this balance. A 2024 study comparing hearing aid users to non-users found that those with blocked ear canals had fewer types of bacteria, making them more vulnerable to pathogens.
Earwax plays a crucial role in self-cleaning, but headphones can interfere with this process. Trapped moisture, especially after exercise, increases humidity and raises the risk of infection and discharge. Experts advise giving ears regular breaks to allow them to 'breathe' and reduce humidity.
If you have an ear infection, avoid using earphones as they may slow recovery. Symptoms such as itchiness, redness, or discharge warrant stopping use and seeking medical advice. Cleaning headphones regularly—weekly or after workouts—with a damp cloth or mild soapy water can help reduce bacterial buildup.
