How health literacy transforms medication use and sleep in older adults

A recent study by Ayan and Elkin has examined how health literacy affects medication use and sleep habits in older adults. Published in 2026, the research highlights a clear link between better health knowledge and improved decision-making in these areas. The findings suggest that stronger health literacy could lead to fewer medication mistakes and better sleep routines.

The study found that older adults with higher health literacy were more likely to follow medication instructions correctly. They also showed a better understanding of potential side effects and engaged more often in discussions with healthcare providers about their treatments. This awareness extended to sleep hygiene, where those with stronger health literacy maintained regular sleep schedules and sought professional help for sleep problems when needed.

Regional and cultural differences played a role in how health literacy influenced these behaviours. Researchers noted that tailored educational programmes could address these variations more effectively. They proposed integrating health literacy checks into routine medical assessments to spot at-risk patients early and design personalised support.

Beyond individual benefits, the study pointed to broader economic advantages. Better health literacy could reduce hospital readmissions by preventing medication errors and improving sleep quality. The authors called for a more integrated approach to elderly care, combining education and empowerment to tackle issues like excessive medication use and sleep disturbances.

The research establishes health literacy as a key factor in helping older adults manage medications and sleep more effectively. By embedding literacy assessments into clinical practice, healthcare systems could identify vulnerable individuals and provide targeted interventions. The study's recommendations may guide future policies aimed at improving long-term health outcomes for ageing populations.
