Overview

• A year-long study of 47 adults aged 65 and older found cognitive performance was optimal when home temperatures stayed between 68–75°F (20–24°C).
• Deviations of 7°F (4°C) in either direction significantly increased the likelihood of attention difficulties, with cold temperatures having a stronger negative effect than heat.
• Older adults' reduced ability to regulate body temperature, compounded by chronic health conditions or medications, makes them particularly vulnerable to indoor climate variations.
• The findings highlight the risks for low-income seniors who may lack resources to maintain optimal indoor temperatures, especially during extreme weather events.
• Researchers call for public health policies, energy-efficient housing, and smart technologies to ensure temperature-controlled environments for aging populations.
