Brain Power

The brain is the most remarkable computer ever created. While we have two kidneys, two lungs, and even the possibility of replacing certain organs if needed, there is only one brain—and no replacement yet. That makes caring for this vital organ one of the most important investments we can make in our overall health and quality of life. The good news is that it is never too late to start.

Why Brain Health Matters

After age 40, the human brain naturally begins to shrink by about 5 percent each decade, affecting memory, focus and mental sharpness. In addition, brain disorders are becoming increasingly common. In 2020, more than 54 million people worldwide lived with Alzheimer’s disease or other dementias—a number projected to rise sharply.

But this is the hopeful part: Research shows that serious cognitive decline is not an inevitable part of aging. Lifestyle choices play a greater role than genetics in determining whether memory-related diseases develop.

Risk Factors for Cognitive Decline

Certain lifestyle habits and health conditions are linked to a higher risk of dementia and other brain disorders, including:

Physical inactivity

Excessive alcohol use

Obesity

Hypertension

Diabetes

Smoking

Depression

High LDL cholesterol

Hearing loss

Visual loss

Social isolation

Traumatic brain injury

Less education

Air pollution

Brain Fitness

Brain fitness is a daily workout for the mind, consisting of activities that strengthen cognition, memory, attention and focus—similar to how exercise builds muscle. 

Benefits include:

Faster thinking and sharper focus

Improved memory

Stronger verbal and listening skills

Enhanced problem-solving and curiosity

Better vision and quicker reactions

Greater ability to finish tasks and projects

Building a brain-friendly lifestyle

Investing in brain health does not require a gym membership. Even 10 minutes a day of intentional practice can make a difference. 

Key strategies include:

Physical exercise: movement that increases blood flow to the brain

Mental stimulation: puzzles, reading, learning new skills, or playing an instrument

Healthy food choices: whole, plant-based meals rich in antioxidants and omega-3s

Connection: staying socially engaged and connected with others

Commitment: actively reducing or eliminating risk factors such as smoking or excessive drinking

A Healthy Challenge

Caring for the brain is not just about preventing disease—it is about living vibrantly, staying engaged and maintaining independence. Small, consistent actions today build a stronger, sharper tomorrow.
