3 Super-Simple Hacks for a Healthy Heart After 50 (#2 Surprised Us!)

Great news: You don’t need a complete lifestyle overhaul to keep your ticker strong for years to come. Exciting new research reveals there are three easy things you can do to keep your heart healthy—and these everyday habits promise to deliver big benefits, including a lower risk of heart attack and conditions such as atrial fibrillation (AFib). Read on to see the heart-smart moves that doctors say are worth trying.

3 easy things you can do for a healthier heart

We all do our best to follow a heart-healthy lifestyle by getting regular physical activity, steering clear of artery-clogging saturated fats and keeping a lid on high blood pressure and high cholesterol. And while those are all important steps toward preventing heart disease and related complications like heart attack and stroke, researchers have found that tiny, day-to-day habits make a big difference, too.

Sleep in a dark room

In a JAMA Network Open study of more than 80,000 adults, researchers found that those who were exposed to the brightest nighttime light had a 47 percent higher risk of heart attack over nine years compared to those who slept in total darkness.

What explains these results? Essentially, the study points to a disruption in the body’s circadian rhythm, says Bharat Sangani, MD, a cardiologist with practices in Gulfport, Mississippi and Dallas. “When the lights are left on, the body does not know if it is day or night.” And that can spell trouble for your heart.

“Research has long shown that poor sleep is associated with an increased risk of heart disease and stroke,” adds Jacob Teitelbaum, MD, author of From Fatigued to Fantastic. “Other studies show that even a little bit of light that is in the ‘blue range’ on the spectrum (basically normal light) triggers adrenaline release during sleep, disrupting sleep quality. This is why the Amazon Kindle and many cell phones have a setting (under ‘display and brightness’) where you can set your phone to ‘night shift’ or warmer vs bright,. ‘Warmer’ basically leaves out the problematic blue light and supports sleep.”

To get the benefit: “Keep the bedroom dark,” says Dr. Teitelbaum, which helps reduce your risk of a heart attack. “This improves sleep quality. Some people use blackout curtains. A much simpler approach is to simply use a sleep mask.”

That said, if the idea of a pitch black bedroom sounds dangerous, you’re not wrong. “If we don’t keep any lights on, there is a greater possibility that accidents causing falls may go up,” says Dr. Sanagani. “That may produce more hospitalization, more pain [and] more surgeries.”

If you need a night light, Dr. Teitelbaum recommends choosing one that uses yellow light instead of blue. “You can readily find these online on Amazon. Simply search on ‘no blue light night lights,’” says Dr. Teitelbaum.

Sip a cup of coffee

Research suggests your daily coffee habit might be heart-protective, thanks to its ability to reduce atrial fibrillation, a heart rhythm disorder that affects millions of adults.

“In layman’s terms, AFib means irregular heart rhythm,” says Dr. Sanagani. “Essentially, for forward-propelling blood from the heart, we need help from two chambers of the heart. Both the chambers contract in sync. In atrial fibrillation, essentially, the atrium stops rhythmically talking to the ventricle. This results in chaotic blood pushing into the ventricle, resulting in less blood in the ventricle and ultimately less blood to the body.”

And while you might assume coffee is a no-go if you have an irregular heartbeat, new research suggests that might not be the case. A JAMA study of 200 adults with atrial fibrillation found that caffeinated coffee drinkers (those who sipped at least a cup a day) had 39 percent lower risk of recurrent AFib episodes than those who skipped the sip.

“This study challenges the age-old wisdom that caffeine stimulates the heart and ultimately may contribute to aggravating irregular heartbeats,” says Dr. Sangani. “There is no clear explanation how and why caffeine effects are opposite to what we have learnt in the past.”

But Dr. Teitelbaum says it may be due to heart-healthy polyphenols, the antioxidant and anti-inflammatory plant compounds found in coffee.

To get the benefit: “I would still exercise some caution for those who have implantable defibrillators for life-threatening ventricular tachycardia,” says Dr. Teitelbaum. Otherwise, talk to your doctor before adding coffee to your routine if you have AFib. Dr. Teitelbaum says two to three cups of coffee a day are typically good for those who won’t feel too overstimulated.

Take vitamin D

New research presented at the 2025 American Heart Association meeting found that adults with heart disease who supplemented to reach healthy blood vitamin D levels had a 52 percent lower risk of a repeat heart attack.

“Numerous nutrients have been associated with decreased heart disease [risk],” says Dr. Teitelbaum. “This study now shows that vitamin D is one of them. It also shows that vitamin D [recommended daily amounts] are not optimal,” as they can leave many of us with a shortfall of this crucial nutrient. (The current RDA for vitamin D for adults is 600 to 800 IU.)

The body makes vitamin D when sunlight strikes skin, but Dr. Teitelbaum notes that many people avoid sun exposure: In fact, 85 percent of the study participants had vitamin D deficiency. Dr. Teitelbaum says vitamin D supports overall heart health by regulating inflammation and immunity, which lowers your risk of heart disease in the process.

To get the benefit: “Avoid sunburn, not sunshine,” Dr. Teitelbaum says. That means spending about 15 to 20 minutes a day outdoors (sans sunscreen), ideally midday to maximize your sun exposure.

And don’t be afraid to supplement with vitamin D. “I recommend that people take a good, high-potency multivitamin that has 1,000 IU of vitamin D, 200 mg of magnesium and high levels of the B vitamins,” says Dr. Teitelbaum. “All of these are associated with a decreased risk of heart disease.”

Start your heart-healthy routine tonight

These three simple shifts—adjusting your bedroom lighting, brewing a cup of morning coffee and boosting your vitamin D levels—are powerful additions to your heart-smart routine. And the best part? You can start any of them tonight. Small habits pack a powerful punch, and your heart is worth the effort.
