Adopting five simple lifestyle habits might just be the key to keeping your brain youthful, as suggested by recent findings. The study posits that these practices could make your brain function as if it were “eight years younger” than your chronological age.

This intriguing phenomenon was particularly evident in individuals dealing with chronic pain, a condition often linked to deteriorating cognitive abilities. The research, published in the Brain Communications journal, delved into how daily habits might impact brain aging in those enduring persistent pain.

According to Medical News Today, the study revealed that participants who engaged in healthy lifestyle behaviors tended to have a younger brain age. In several cases, their brain age appeared up to eight years younger than their actual age.

The investigation involved a team from three U.S. universities, who analyzed data from over 100 adults aged 45 to 85 over a span of two years. These individuals were part of a larger observational study focused on pain and the risk of developing osteoarthritis.

Researchers assessed each participant’s chronic pain severity on a scale from one to five, where one meant little to no chronic pain and five signified severe chronic pain. They also evaluated lifestyle choices and psychological factors, such as smoking, waist size, sleep quality, stress levels, and optimism.

Using this data, the team calculated a “protective score.” At the study’s outset, those with higher protective scores, including those with chronic pain, showed brain ages that were up to eight years younger than their actual age.

Conversely, those with reduced protective scores displayed brain ages exceeding their chronological years. Following a two-year period, participants maintaining the most wholesome lifestyle patterns continued to exhibit younger brain ages.

This implies that beneficial habits may exert lasting effects on cognitive wellbeing. The five most crucial protective elements for brain age amongst those suffering from chronic pain were identified as:

• Practising good sleep hygiene
• Maintaining a healthy body weight
• Avoiding tobacco
• Good stress management strategies
• Maintaining positive social ties

The study’s authors noted: “Our results indicate that while chronic pain is correlated with overall brain structure, socioenvironmental and behavioural/psychosocial factors appear to play a more significant role.

“Given that the behavioural/psychosocial factors correlate with brain age over time and are potentially modifiable, the protective factors provide a set of potential clinical targets (e.g. sleep, smoking, social support) for interventions that might reduce brain ageing in middle and old age within and without the context of chronic pain.”

This isn’t the first instance where these elements have been associated with brain health. A pioneering study, published in The Lancet, previously linked some of these factors to the risk of dementia.

The researchers identified 14 lifestyle factors that could potentially increase the risk of dementia in approximately 45% of cases. These included:

• Midlife smoking – a potential 2% reduction in dementia cases if this risk factor is eliminated
• Midlife obesity – 1%
• Late-life social isolation – 5%

The remaining risk factors were less education in early life, hearing loss, high cholesterol, depression, traumatic brain injury, physical inactivity, diabetes, hypertension, excessive alcohol, air pollution, and visual loss.
