Brain Health After 65: Everyday Habits That Support Healthy Aging

Your brain plays an important role in nearly everything you do, from remembering important information and making decisions to communicating with others and completing everyday activities.

As you get older, it is normal to notice some changes in how quickly you process or remember information. However, significant memory loss that interferes with daily life is not considered a normal part of aging.

The good news is that healthy habits can help support your brain health at any age. Many of the same activities that support your heart and overall health may also help protect your brain.

While no single habit can guarantee the prevention of Alzheimer's disease or other forms of dementia, making small, consistent changes can support healthy aging and overall well-being.

1. Stay Physically Active

Regular physical activity supports blood circulation, heart health, and overall brain function. Research suggests that staying physically active may help maintain memory and thinking abilities as you age.

You do not have to participate in strenuous exercise to benefit from movement.

Activities to consider include:

• Walking indoors or outdoors
• Swimming or water aerobics
• Chair exercises
• Gentle stretching
• Gardening
• Dancing
• Balance and strengthening exercises

Tips for Getting Started

• Choose activities you enjoy and can perform comfortably.
• Start with short periods of activity and gradually increase as tolerated.
• Break activity into smaller sessions throughout the day if needed.
• Avoid sitting for long periods when possible.
• Consider exercising with a friend or family member for motivation.

Important: Before beginning a new exercise program or increasing your activity level, consult your healthcare provider to determine what types and amounts of physical activity are safe for you, especially if you have heart disease, lung disease, arthritis, balance difficulties, or other chronic medical conditions.

2. Stay Socially Connected

Spending time with others can support emotional well-being and provide opportunities to keep your mind engaged.

Social isolation and loneliness have been associated with an increased risk of cognitive decline and other health concerns.

Ways to Stay Connected

• Schedule regular phone calls with family or friends.
• Join a book club, hobby group, or community organization.
• Participate in activities at a local senior center.
• Attend community or faith-based gatherings if you enjoy them.
• Volunteer for a cause that interests you.
• Play cards, board games, or puzzles with others.
• Use video calls to stay connected with loved ones who live far away.

Remember: Meaningful social connections do not have to involve large groups. Even regular conversations with a friend or family member can help you feel connected and engaged.

If you are experiencing loneliness or have difficulty participating in social activities, talk with your healthcare provider about community resources that may be available.

3. Make Sleep a Priority

Sleep is important for memory, concentration, learning, and overall brain health.

Poor sleep may make it harder to focus, remember information, and manage daily activities.

Most adults age 65 and older generally need approximately 7–8 hours of sleep each night, although individual needs may vary.

Healthy Sleep Habits

• Go to bed and wake up at approximately the same time each day.
• Keep your bedroom quiet, dark, and comfortable.
• Limit caffeine later in the day.
• Avoid large meals close to bedtime if they interfere with sleep.
• Establish a relaxing bedtime routine.
• Limit screen use before bedtime if it makes falling asleep difficult.
• Stay physically active during the day, as recommended by your healthcare provider.

When Sleep Problems Need Attention

Talk with your healthcare provider if you:

• Frequently have trouble falling or staying asleep.
• Feel excessively sleepy during the day.
• Snore loudly or have been told you stop breathing during sleep.
• Wake up feeling unrefreshed despite getting enough hours of sleep.

Sleep disorders, including sleep apnea, may affect both sleep quality and overall health.

Do not start sleep medications or supplements without discussing them with your healthcare provider, as some products can cause side effects or interact with other medications.

4. Manage Diabetes and Blood Sugar

Diabetes can affect blood vessels and nerves throughout the body, including those that support brain function.

Over time, poorly controlled blood sugar may contribute to blood vessel damage and increase the risk of stroke and cognitive problems.

Episodes of low blood sugar can also cause temporary confusion, difficulty concentrating, dizziness, or weakness.

Tips for Managing Diabetes

• Take diabetes medications exactly as prescribed.
• Monitor your blood sugar as directed by your healthcare provider.
• Follow an individualized eating plan.
• Keep regular medical appointments.
• Discuss repeated high or low blood sugar readings with your healthcare provider.
• Learn the signs of low blood sugar and how to respond according to your diabetes care plan.

Important: Blood sugar goals may differ for older adults depending on their medications, other medical conditions, and risk of low blood sugar. Ask your healthcare provider what blood sugar targets are appropriate for you.

5. Keep Your Blood Pressure Under Control

High blood pressure can damage blood vessels over time, including those that supply oxygen and nutrients to your brain.

Managing blood pressure may help lower your risk of stroke and other cardiovascular complications. Research also suggests that appropriate blood pressure management may help reduce the risk of cognitive decline.

Tips for Healthy Blood Pressure

• Take blood pressure medications as prescribed.
• Check your blood pressure at home if recommended.
• Keep a record of your readings.
• Follow your healthcare provider's sodium recommendations.
• Stay physically active as appropriate.
• Avoid tobacco products.
• Attend regular follow-up appointments.

Important: Blood pressure goals should be individualized, particularly for older adults who experience dizziness, falls, or low blood pressure. Ask your healthcare provider what blood pressure range is right for you.

6. Protect Your Hearing and Vision

Hearing and vision are important for communication, learning, and staying connected with the world around you.

Untreated hearing loss has been associated with an increased risk of cognitive decline and dementia.

Hearing difficulties may also make it harder to follow conversations, participate in social activities, and understand important information.

Ways to Support Hearing and Vision Health

• Schedule hearing evaluations if you notice difficulty hearing.
• Use hearing aids as recommended.
• Keep hearing aids clean and properly maintained.
• Protect your ears from excessively loud noises.
• Have regular eye examinations as recommended.
• Wear prescribed glasses or other corrective lenses.
• Tell your healthcare provider if you notice changes in your hearing or vision.

Addressing hearing and vision problems can make everyday activities and social interactions easier.

Remember: Sudden hearing loss requires urgent medical evaluation. Sudden vision loss or vision changes accompanied by other stroke symptoms require emergency medical attention.

7. Eat Foods That Support Brain Health

A balanced eating pattern provides nutrients that support the brain, heart, and blood vessels.

Research suggests that eating patterns emphasizing vegetables, fruits, whole grains, fish, and healthy fats—such as the Mediterranean-style and MIND diets—may be associated with better cognitive health.

Foods to Include

Vegetables and Fruits

Choose a variety of colorful produce, such as:

• Leafy greens
• Broccoli
• Carrots
• Berries
• Apples
• Oranges

Whole Grains

Examples include:

• Oatmeal
• Brown rice
• Whole wheat bread
• Quinoa

Lean Proteins

Examples include:

• Fish
• Chicken or turkey
• Beans and lentils
• Eggs
• Tofu

Healthy Fats

Examples include:

• Olive oil
• Avocados
• Nuts
• Seeds

Foods to Limit

Try to limit:

• Highly processed foods
• Foods high in saturated fat
• Excess sodium
• Sugary beverages
• Foods high in added sugar

Stay Hydrated

Not drinking enough fluids can contribute to dehydration, which may cause fatigue, dizziness, and confusion.

Ask your healthcare provider how much fluid is appropriate for you, especially if you have heart failure, kidney disease, liver disease, or another condition requiring a fluid restriction.

Important: Before making significant dietary changes, consult your healthcare provider or registered dietitian to determine what is appropriate for your individual medical conditions and nutritional needs.

8. Keep Your Mind Engaged

Activities that challenge your thinking can provide opportunities to practice memory, attention, language, and problem-solving.

Activities to Try

• Read books, newspapers, or magazines.
• Complete crossword puzzles or word searches.
• Play cards or board games.
• Learn a new hobby or skill.
• Practice a new language.
• Work on jigsaw puzzles.
• Take a class.
• Participate in creative activities such as painting or music.
• Try online memory games or brain-training activities.
• Choose activities that are enjoyable and appropriately challenging.

Brain games can help you practice certain thinking skills, but they have not been proven to prevent Alzheimer's disease or dementia.

9. Avoid Tobacco and Discuss Alcohol Use

Smoking damages blood vessels and increases the risk of stroke and other health problems that can affect the brain.

Quitting smoking can benefit your health at any age.

Alcohol may also affect memory, balance, sleep, and medication safety. Older adults may be more sensitive to its effects.

Helpful Tips

• Avoid smoking and secondhand smoke.
• Ask your healthcare provider about smoking cessation resources if needed.
• Discuss whether alcohol is safe for you based on your medications and medical conditions.
• Avoid using alcohol as a sleep aid.

10. Review Your Medications Regularly

Some medications can affect memory, alertness, and concentration, especially in older adults who take several prescriptions.

Certain sleep medications, allergy medications, pain medications, and medications with anticholinergic effects may contribute to confusion or memory difficulties.

Medication Safety Tips

• Keep an updated list of all prescription medications, over-the-counter products, vitamins, and supplements.
• Review your medication list regularly with your healthcare provider or pharmacist.
• Report new confusion, dizziness, or memory problems after medication changes.
• Take medications exactly as prescribed.

Never stop or change prescribed medications without first discussing them with your healthcare provider.

When to Call Your Healthcare Provider

Contact your healthcare provider if you:

• Notice new or gradually worsening memory problems.
• Frequently forget important appointments, conversations, or events.
• Have difficulty completing familiar daily activities.
• Experience increasing confusion or difficulty concentrating.
• Notice changes in mood, behavior, or personality.
• Have ongoing sleep problems or excessive daytime sleepiness.
• Experience frequent episodes of low or high blood sugar.
• Have blood pressure readings outside your recommended range.
• Notice hearing or vision changes.
• Have difficulty managing medications or following your treatment plan.
• Have family members or friends who express concern about changes in your memory or thinking.

Memory changes can have many possible causes, including medications, sleep problems, vitamin deficiencies, depression, and other medical conditions.

Always ask your healthcare provider for specific advice on when to call to report symptoms, and when to seek urgent/emergency care.

Do not assume that significant memory loss is simply a normal part of aging. Early evaluation can help identify possible causes and determine whether additional care is needed.
