Users of earphones, especially in hot and humid conditions, are warned against a growing health concern: 'ear fungus'. The often-prolonged use of earphones can lead to a moist environment, fostering the growth of fungi. It can lead to symptoms such as itching, pain or hearing impairment. Japanese health organizations are now raising awareness to try and combat this occurrence, urging people to maintain ear hygiene and take regular breaks when using earphones.

In Japan, details such as cleanliness and health are highly regarded societal values. Therefore, this topic is receiving substantial media attention. The rise in ear fungus incidents might be correlated with the popularity of earphones due to increased remote work, online schooling, and personal entertainment preference, making it a current and relevant concern for many.

This issue is not unique to Japan and is relatable worldwide due to the global use of earphones. In the US or EU, similar awareness campaigns would likely be carried out by health departments or organizations. It is also common practice in these regions to encourage regular hygiene and the practice of safe habits to prevent health disorders.
