Small daily habits that help protect your brain as you age

Experts say brain health in aging hinges on daily habits that build cognitive reserve: stay mentally active and keep learning, exercise regularly (about 30–35 minutes of aerobic activity 4 times per week plus strength and flexibility twice weekly), wear helmets and seat belts to prevent head injuries, quit smoking, control blood pressure and diabetes, eat a healthy, less-processed diet, maintain a healthy weight, and get seven hours or more of sleep. These actions, highlighted by the Alzheimer's Association, can delay cognitive decline and reduce dementia risk.
