4. Stay Physically Active

Exercise boosts blood flow to the brain and supports overall cognitive health.

5. Limit Alcohol

Excessive drinking is linked to brain shrinkage and cognitive decline. Keep alcohol intake moderate.

6. Prevent Head Injuries

Wear helmets when biking or doing risky activities. Protect your head during sports or falls.

7. Stay Socially Connected

Spending time with others, joining clubs, or volunteering helps protect your brain from isolation-related decline.

8. Get Enough Vitamin B

Especially B12 and folate, which support brain and nerve function.

9. Quit Smoking

Smoking damages blood vessels, reducing oxygen to the brain and increasing the risk of dementia.

Taking small steps now — like eating better, exercising regularly, and protecting your brain — can help you stay mentally sharp for years to come.
