How heart-healthy habits can also support brain health

After years of working in brain health, one of the clearest lessons is that healthy blood vessels play a major role in keeping the brain functioning well. That makes sense: the brain depends on blood flow, perfusion, and oxygen delivery, and it also helps regulate those processes.

For that reason, many of the best ways to protect brain health are the same habits long recommended for the heart. Here is a closer look at how supporting vascular health can benefit both organs.

Stay Active

Exercise helps the heart pump more efficiently and promotes healthy circulation throughout the body, including the brain. Regular movement may also help lower blood pressure, improve blood sugar control, reduce stress, and support better mood and sleep. Over time, these benefits may lower the risk of stroke and cognitive decline.

A good goal is about 150 minutes of moderate activity each week, such as brisk walking, swimming, or cycling. That could be as simple as walking for 30 minutes, five days a week. If possible, add muscle-strengthening exercise on two days.

If a 30-minute session feels like too much, begin with 10 minutes. Walk after dinner, take the stairs when you can, or join a local exercise class. The best routine is one you enjoy enough to stick with. If you have mobility limits or a medical condition, talk with your healthcare team about safe options.

Monitor Your Numbers

High blood pressure is often called a silent condition because it may cause no symptoms, yet it can still damage the small blood vessels that supply the brain. Uncontrolled blood pressure raises the risk of stroke and is tied to later problems with memory and thinking.

Get your blood pressure checked regularly. For most adults, a reading under 120/80 is considered normal, though treatment goals can vary by person. If you check it at home, use an upper-arm cuff that fits properly. Before measuring, sit quietly for five minutes with your feet flat and your arm supported at heart level.

To help manage blood pressure, use less salt when cooking, choose more fresh foods, stay active, and take prescribed medication consistently. Share your readings with your healthcare provider instead of adjusting medicine on your own.

Protect the Arteries: Cholesterol

Cholesterol is necessary for the body, but too much LDL, often called bad cholesterol, can contribute to plaque buildup in the arteries. Narrowed or blocked arteries can lead to heart attacks or strokes, and poor vascular health may also affect memory and thinking over time.

Ask your healthcare provider about cholesterol testing and what your results mean for your personal risk. At home, choose more fiber-rich foods such as oatmeal, beans, vegetables, and fruit. Try replacing some butter and fatty meats with olive oil, nuts, fish, and other unsaturated fats.

Stop Smoking

Smoking harms blood vessels, raises the risk of blood clots, and makes it harder for blood to carry oxygen. Those effects threaten both heart and brain health, and secondhand smoke is harmful too.

Quitting can help at any age, even after years of smoking. Set a quit date, think about what triggers cravings, and let a friend or family member know how they can support you. Nicotine patches, gum, and other medications can help ease withdrawal, and counseling can improve success. Free help is available by calling 1-800-QUIT-NOW.

Manage Diabetes

The brain needs glucose for energy, but blood sugar that stays too high can damage blood vessels over time. Diabetes is also linked to a higher risk of stroke and cognitive problems. Blood sugar that drops too low can interfere with clear thinking as well, so stable levels matter.

Ask about the A1C test, which reflects average blood sugar over roughly three months, and find out what your target should be. Build meals around vegetables, fiber-rich carbohydrates, and protein. Choose water more often than sugary drinks, stay physically active, and take medication as directed. If you take diabetes medicine that can cause low blood sugar, ask how to recognize and treat it.

Taking care of your vascular health gives you a double benefit because it also supports your brain, so this part of your health deserves attention.
