6 Simple Changes to Prevent an Early Death

How to Live Longer: Essential Lifestyle Adjustments for Brain Health

As a baby boomer or Gen X, dementia is often perceived as an inevitable consequence of aging. However, it can be significantly mitigated through targeted lifestyle adjustments. Recent insights suggest that up to 40% of dementia cases could be delayed or even prevented by adopting certain habits early in life. Yet, it is never too late to start.

Presently, 12 modifiable risk factors correlate with heightened dementia risk. By proactively addressing these factors, individuals can exert substantial influence on their brain health and overall well-being, thereby diminishing the likelihood of developing dementia now or in later years.

Embrace Good Nutrition

Nutrition plays a pivotal role in brain health due to its disproportionate energy consumption. Around 20% of daily energy is dedicated to brain function, despite the brain comprising only 2% of body weight. A balanced diet not only helps maintain a healthy body weight and reduces diabetes risk, but also mitigates hypertension, both significant dementia risk factors.

Whole food Mediterranean-type diets, rich in whole grains, vegetables, fruits (especially berries), lean meats, nuts, beans, and oily fish, are consistently associated with enhanced brain function and reduced dementia risk. Limiting the intake of ultra-processed foods, pastries, sweets, sugary drinks, and foods fried in seed oils further supports brain health. Dietary improvements are generally preferred over reliance on supplements, unless addressing specific nutrient deficiencies.

Ensure Adequate Hydration

Given that the human body is approximately 60% water, maintaining proper hydration is essential for optimal brain function and overall well-being. Dehydration can impair physical and mental performance, affecting memory, attention span, concentration, and reaction times. Adequate hydration supports optimal brain performance and helps stave off declines in cognitive function.

Moderate Alcohol Consumption

Research underscores that excessive alcohol consumption increases dementia risk by altering brain structure. This leads to neuronal loss, decreased white matter integrity, and reduced brain volume, all of which impact cognitive function. While exceeding 21 units of alcohol weekly heightens dementia risk, health guidelines recommend limiting intake to no more than 14 units weekly to maintain overall health. Beyond dementia risk, excessive alcohol consumption also heightens susceptibility to certain cancers, including mouth, throat, and breast cancers, as well as stroke and heart disease.

Engage in Regular Physical Activity

Exercise enhances brain health by increasing cerebral blood flow, reducing inflammation, and enhancing brain activity and volume. These benefits contribute significantly to long-term brain health and are believed to protect against cognitive decline. Guidelines recommend at least 150 minutes of moderate-intensity physical activity per week, 75 minutes of high-intensity exercise per week, or a combination of both. Studies suggest that achieving as few as 7,500 steps daily can enhance brain volume.

Foster Social Connections

Social isolation and loneliness are associated with heightened risks of depression and cognitive decline. Maintaining robust social connections, such as living with others, participating in community activities, and regularly interacting with family and friends, has been linked to slower rates of cognitive decline. Social engagement stimulates attention, memory, and strengthens neural networks, thereby contributing to sustained brain health.

Continual Learning

Lifelong learning significantly contributes to brain health, reducing dementia risk by fostering neuroplasticity and cognitive resilience. Activities such as learning new languages, acquiring new skills like playing a musical instrument, and engaging in mentally stimulating tasks, such as puzzles, are particularly beneficial. Lifelong learning can also be tied to extending both lifespan and healthspan. Taking an interest in longevity-related YouTube channels, podcasts, subscribing to newsletters, and reading scientific articles keeps the brain active and engaged.

Address Hearing Loss

Addressing factors such as hearing loss is essential. Using hearing aids helps with inclusion and reduces feelings of loneliness and isolation. This intervention is closely tied to fostering and maintaining regular social connections.

Prioritize Quality Sleep

Numerous scientific studies recommend getting 7 to 9 hours of sleep per night and maintaining a regular bedtime, ideally after 8 p.m. but before 11 p.m. Consistent wake-up times, even on weekends, are crucial. A sleep environment that is cooler and darker than the rest of the home promotes better sleep quality.

Deep and REM sleep are vital. While there is no universally endorsed requirement, a goal of at least one hour each of deep and REM sleep per night is a worthy target. Investing in a fitness tracker, smartwatch, or smart ring can help monitor sleep quality and ensure individuals are meeting their goals.

The Vital Role of Early and Consistent Care

The brain is arguably the body’s most vital organ, benefiting immensely from early and consistent care. By implementing these lifestyle modifications at any age, individuals can substantially enhance brain health, ensuring its continued optimal function as they age. These practices not only reduce the risk of dementia but also promote overall well-being, underscoring the profound impact of lifestyle choices on long-term brain health. A healthy and active brain and body contribute to a longer life, extended healthspan, greater independence, and less reliance on the support of others.
