In today’s fast-paced world, our physical health often takes center stage—whether it’s through gym workouts, dieting, or using wearable tech to track every step. But there’s a crucial factor that many overlook: brain health. When we neglect the health of our brain, it can significantly hinder our ability to meet physical goals and tackle life’s challenges.
Research consistently underscores the importance of mental well-being. However, it often takes a backseat compared to physical health. According to a survey conducted by YouGov in 2024, the most popular New Year’s resolutions in the UK were all centered around physical goals—exercise, weight loss, dieting, and saving money. Yet, about 20% of people reported failing at these resolutions within just six days. Interestingly, mental health barely made the list, with only 5% of participants citing it as a priority for the year ahead.
Monitoring physical health is relatively straightforward with the help of mobile devices and wearable technology, but when it comes to assessing and improving brain health, the path is less clear. In their new book Brain Boost: Healthy Habits for a Happier Life, researchers emphasize the importance of mental health and offer practical tips drawn from the latest scientific findings.
Why Mental Well-Being Matters for Overall Happiness
Our mental well-being is crucial to our quality of life. It enables us to handle stress, build resilience, and contribute meaningfully to society. Studies have shown that cognitive health is closely linked to overall happiness. The 2024 World Happiness Report revealed that the five happiest countries are all in Scandinavia, with Finland, Denmark, Iceland, Norway, and Sweden taking the top spots. Meanwhile, the UK and the US failed to make the top 10.
In the UK, a YouGov survey showed that while happiness is the most commonly expressed emotion, only 45% of people feel happy. Frustration and stress are more commonly reported emotions, with 40% and 35% of people feeling these emotions, respectively. Optimism is also low, particularly among younger and older generations. Only 23% of 18- to 24-year-olds and 17% of those aged 45–54 report feeling optimistic.
Happiness and well-being have a significant impact on physical health. Studies show that people who are happy experience lower levels of stress and greater longevity. Therefore, prioritizing brain health is not just beneficial for mental well-being—it’s essential for overall health.
Nurturing Your Brain for Physical Success
In Brain Boost, the authors present seven lifestyle factors that play a critical role in improving brain health, cognition, and well-being. These include exercise, diet, sleep, social interaction, kindness, mindfulness, and learning. Importantly, these habits can also enhance physical health and improve your chances of achieving your fitness goals.
For instance, exercise is a double-edged sword—improving both physical and cognitive health. Studies show that regular physical activity can increase the size of the hippocampus, the part of the brain responsible for learning and memory. Furthermore, getting enough sleep is crucial for maintaining cognitive function and mental health. The authors found that adults who slept 7–8 hours a night had better brain structure, faster processing speeds, and stronger memories.
Social connections also play a vital role in brain health. Research shows that social isolation increases the risk of dementia in older adults by 26%. In contrast, having a healthy social circle in adolescence can lead to better brain function, improved cognitive performance, and better educational outcomes.
Learning new skills is another key factor in boosting brain health. Whether it’s picking up a new language, playing an instrument, or simply reading an educational book, challenging your brain helps build cognitive reserve and enhances mental resilience.
The Bottom Line: Prioritize Your Brain
While physical health is important, we cannot ignore the significance of mental well-being. Embracing simple strategies to improve brain health—such as regular exercise, social interaction, and mental challenges—can enhance cognitive function, improve mood, and make it easier to achieve physical goals. Brain health is not only essential for mental sharpness but also for resilience against diseases like dementia.
Prioritizing brain health, alongside physical health, sets the foundation for a happier, healthier, and more fulfilling life.
