Harvard-affiliated researchers found a strong connection between indoor temperature and brain health in older adults. Their year-long study tracked 47 adults aged 65+, revealing that maintaining home temperatures between 20°C and 24°C helps preserve cognitive function and reduces dementia risk. The findings indicate that lower temperatures increase mental decline risk, while excessively warm conditions may contribute to dehydration and sleep disruptions. The study underscores the importance of environmental factors in aging and cognitive health.
The study revealed that older adults living in homes with ambient temperatures between 20°C and 24°C experienced the least difficulty concentrating.
Researchers found cognitive risks doubled when indoor temperatures shifted by just 4°C in either direction outside the range, highlighting the balance needed.
