Simple Lifestyle Changes Can Significantly Boost Brain Health, Neuroscience Columnist Finds

A year-long experiment in adopting science-backed habits dramatically improved the well-being of neuroscience columnist Helen Thomson and her family, demonstrating the powerful link between daily routines and cognitive function. The transformation, detailed in New Scientist, highlights accessible strategies for enhancing brain health at any age.
The Power of Diet and Supplements
The initial shift focused on nutrition and supplementation. Thomson began each morning with creatine dissolved in water, alongside a multivitamin and natural yogurt rich in beneficial bacteria. This decision was informed by a large clinical trial involving older adults, which revealed that daily multivitamin consumption can slow cognitive decline by over 50%. Creatine, recommended by consulted experts, provides a vital energy source for the brain during periods of high demand.
However, the most impactful dietary change extended beyond supplements to the weekly grocery shopping. After consulting with neuroscientists and nutritionists, Thomson recognized the critical role of the intestinal microbiome in both mental and cognitive health.
Cultivating a Healthy Gut Microbiome
Following the advice of epidemiologist Tim Spector, the family incorporated three servings of fermented foods daily, eliminated ultra-processed foods from breakfast, and prioritized a diverse diet based on whole foods. This strategy, according to New Scientist, aims to promote bacterial diversity, a key factor in brain health. The microbiome, comprised of trillions of bacteria in the gut, is increasingly recognized for its influence on cognitive function and its potential to lower the risk of neurodegenerative diseases. Consequently, Thomson’s family regularly consumed kefir, yogurt, and sauerkraut, while also increasing their intake of vegetables and whole grains.
Harnessing the Benefits of Cold, Heat, and Nature
Beyond diet, regular exposure to both cold and heat became a priority. Thomson described a routine of cold water immersion followed by sauna sessions after dropping her children at school. Scientific evidence cited by New Scientist suggests these practices can reduce inflammation and stress, while also strengthening connectivity between brain networks responsible for emotional regulation, decision-making, and attention. These effects may explain the observed link between these practices and improved mental well-being.
Physical activity and contact with nature were also integrated into the family’s daily life. Daily walks in the park and gardening not only promoted physical health but also contributed to increasing the diversity of beneficial intestinal bacteria. Furthermore, spending time in natural environments, such as forests, has been shown to enhance memory, cognition, and offer protection against depression.
Cognitive Stimulation for a Resilient Brain
To actively challenge their brains, Thomson and her children dedicated time to language learning through apps, recognizing the benefits extend beyond linguistic skills to strengthening cognitive reserve – the brain’s defense against aging. Thomson also resumed playing the piano, recalling the insight from York University’s Ellen Bialystok: “What’s hard for the brain is good for the brain.” These mental challenges help maintain mental acuity and prevent age-related decline.
Tangible Results and a Continued Pursuit
The positive effects of these changes were quickly apparent. Thomson observed calmer children, increased mental clarity, and a boost in daily energy levels within her family. While acknowledging the possibility of a placebo effect, she believes the combination of these habits has had a genuine impact on their quality of life.
Looking ahead, Thomson intends to continue exploring simple, science-backed methods for maintaining optimal brain health, a pursuit that, as she shared with New Scientist, will continue to shape her daily routine.
