With approximately 30% of Japan's population aged 65 or older, the urgency to address pollution-related health issues is paramount, as this demographic represents the second-highest proportion of elderly individuals globally.

A recent study from the University of Tokyo, published in Nature Sustainability, highlights the significant health risks posed by fine particle pollution (PM2.5) to the elderly population in Japan.

The research analyzed 170,000 medical records, revealing that individuals over 65 are disproportionately affected by PM2.5 exposure and often face disparities in accessing medical care.

Illness among older adults can impose significant financial and emotional strain on families, as many may need to retire earlier than planned due to health complications from PM2.5 exposure.

The health challenges faced by the elderly are framed as a public issue with substantial social and economic implications, underscoring the need for immediate action to save lives and reduce costs.

Researchers advocate for stricter pollution control policies, increased green infrastructure in urban areas, and enhanced public health support specifically targeting the elderly.

Lead author Yin Long pointed out that aging weakens immune systems, making older adults more susceptible to pollutants, which can exacerbate existing health conditions.

Fine particle pollution is associated with serious health issues such as heart attacks, strokes, and respiratory diseases, leading to increased hospitalization and premature mortality among the elderly.

Many elderly individuals reside in rural areas with limited healthcare infrastructure, complicating their ability to receive treatment for pollution-related health issues.

To improve healthcare access for older adults in remote areas, strengthening telemedicine services is also recommended.

Currently, PM2.5 levels in Japan are 1.7 times higher than the World Health Organization's recommended limit, contributing to significant health threats for the elderly.

Addressing these pollution-related health risks is essential not only for the well-being of older adults but also for the overall health of the community.
