Indoor Temperature Significantly Affects Cognitive Function in Seniors

Research shows that maintaining indoor temperatures between 68–75 °F is crucial for preventing cognitive decline in older adults, especially amid rising global temperatures.

Recent research highlights a troubling link between indoor temperature and cognitive function in older adults.

Findings indicate that temperatures outside the optimal range of 68–75 °F (20–24 °C) can adversely affect attention levels, emphasizing the urgent need for climate-resilient housing strategies to protect the cognitive health of seniors in the face of global temperature changes.

Impact of High Indoor Temperatures

The association between high indoor temperatures and cognitive decline is garnering significant attention.

A key study from the Hinda and Arthur Marcus Institute for Aging Research, affiliated with Hebrew SeniorLife and Harvard Medical School, reveals that older adults achieve their best cognitive performance when indoor temperatures are maintained within the recommended range.

The research shows that even a 7°F (4°C) deviation can double the likelihood of experiencing attention difficulties.

Longitudinal Study Findings

This longitudinal observational study monitored the home temperatures and self-reported attention issues of 47 community-dwelling adults aged 65 and older over a year.

Results published in the Journal of Gerontology: Medical Sciences indicate that many older people may be living in conditions that hinder their cognitive performance.

This concern is especially critical for low-income and underserved populations who often lack the resources to regulate their indoor environments effectively.

Call for Climate-Resilient Strategies

The lead researcher, Amir Baniassadi, emphasizes the importance of understanding how environmental factors, such as indoor temperatures, affect the cognitive health of aging people.

The study underscores the pressing need for public health strategies and housing frameworks focused on climate resilience for seniors.

With global temperatures on the rise, ensuring access to properly temperature-controlled living spaces is essential for safeguarding cognitive health.

This research expands upon a 2023 study that examined the impact of temperature on the sleep and cognitive abilities of older adults, broadening the perspective that climate change affects not only physical health but also mental acuity.

To tackle these issues, potential solutions could include the adoption of smart home technologies that automatically adjust indoor temperatures, improving housing energy efficiency, and enhancing access to cooling amenities.
