Although we can’t completely prevent the natural effects of aging, there’s plenty that you can do to keep your brain sharp as you age.
Give your brain a workout
Do activities that make you think, solve problems, and recall information. Activities like this may help to stimulate your brain and keep it in shape. Examples include things like doing crossword puzzles, doing arts and crafts, or learning a new skill.
Not only is exercise good for your overall health, but physical activity can increase blood flow to your brain. Try to do some form of aerobic exercise for 30 minutes most days of the week.
Spending time with family and friends can help keep your brain stimulated and combat things like depression or stress. You may also consider volunteering with a local organization.
Eat a healthy diet
Try to focus your diet so that it’s rich in vegetables, fruits, and whole grains. Choose healthy protein sources such as nuts, fish, and chicken.
Address other health conditions
Some conditions can increase your risk of cognitive decline or dementia as you age. If you have a condition such as diabetes, high blood pressure, or high cholesterol, be sure to work with your doctor to keep it under control.
Keep your head protected
Traumatic brain injuries can cause issues with cognition. Remember to always wear a helmet when performing activities such as biking or playing contact sports.
