Nutrition and Sleep: Key Factors in Maintaining Cognitive Health

Many people experience declines in cognitive abilities and reduced concentration as they age, but research indicates that certain lifestyle habits can help preserve brain function. A study published in Frontiers in Nutrition highlights the role of B vitamins and proper sleep in maintaining cognitive health among the elderly.

The study, conducted by Chinese researchers, involved nearly 9,000 participants aged 65 and older in Shanghai. The team analyzed dietary data with a focus on vitamin B6, B12, and folic acid intake, alongside the number and quality of hours of sleep.

Results showed that higher consumption of these B vitamins was associated with a lower risk of cognitive decline, while insufficient sleep correlated with memory impairment and decreased attention and overall brain performance. The most significant protective effect was observed when participants increased their intake from low to moderate levels of B vitamins.

Previous research supports these findings, indicating that adequate sleep reduces stress and blood pressure, both of which positively impact brain health. Additionally, B vitamins are known to play a critical role in supporting the nervous system and enhancing memory and information-processing abilities.

The study provides practical guidance for older adults seeking to maintain cognitive function: ensuring sufficient nightly rest and maintaining moderate intake of B vitamins may serve as accessible strategies to protect the brain from age-related decline.
