Not our usual tips: 5 surprising daily habits that a popular cardiologist trusts for a healthy heart

Most health advice about the heart sounds the same—eat clean, exercise more, avoid stress. While all of that holds true, there are some lesser-known habits that quietly nourish the heart in powerful ways. Dr Jack Wolfson, a well-known cardiologist and health educator, shared 5 such daily practices in a recent post that are not only backed by science but also deeply rooted in how humans are naturally wired to live. These aren’t flashy hacks—they’re gentle shifts that can bring a surprising sense of balance to both the heart and mind.

Here’s a look at these unusual but effective habits, with a closer understanding of why they matter.

According to Dr Jack, daily outdoor exposure can significantly cut down the chances of heart disease. Why? It’s not just the sun or fresh air—it’s the subtle rhythm of nature, the movement involved, and a break from digital overload. A 2019 study found that spending at least 120 minutes per week in natural environments is linked to good health and well-being. The simple act of being under the sky, walking on grass, or sitting near trees helps regulate blood pressure and reduce stress hormones like cortisol, which are known to harm the heart over time.

Dr Jack advises moving bedtime an hour earlier than usual—not just to clock in more sleep, but to allow the body to follow its natural circadian rhythm. Deep, uninterrupted sleep between 10 PM and 2 AM is when the body does its most essential repair work, including cardiac muscle recovery and hormone balance. Chronic late nights disrupt melatonin and increase nighttime blood pressure, both harmful to heart health. A study showed that people who slept between 10 and 11 PM had a lower risk of cardiovascular issues than those who went to bed later.

Excess screen time, especially before bed, is linked with elevated heart rate, poor sleep, and increased mental clutter. Dr Jack suggests simply cutting back—not banning devices altogether. This opens time for natural movement, real-world connection, and better sleep cycles. Studies have found that even 30 minutes less screen time daily improves heart rate variability (HRV), a key marker of heart resilience. The blue light from screens, along with the constant stimulation, can spike adrenaline levels, keeping the body in a low-grade stress mode that burdens the heart.

Grounding—or standing barefoot on soil, grass, or sand—is a practice that’s quietly gaining respect among health experts. Dr Jack recommends it for heart health due to its anti-inflammatory effects. The earth carries a mild negative charge, and skin-to-earth contact may help neutralise positively charged free radicals, easing oxidative stress. While research is still growing, a small study in the Journal of Environmental and Public Health (2012) showed that grounding improved blood viscosity, a major factor in cardiovascular health.

Gratitude lowers stress, calms the nervous system, and shifts the body into a parasympathetic (rest-and-digest) state. Dr Jack encourages a daily moment of thanks, not just as a spiritual practice, but as a biological reset. When the brain experiences gratitude, it lowers cortisol levels and boosts feel-good hormones like dopamine. A study published in Psychosomatic Medicine found that heart patients who practised daily gratitude had better heart rate variability and emotional resilience during recovery.

While these habits are powerful, they work best when paired with consistency and awareness. No single habit acts like a magic pill—but together, they form a lifestyle that is gentle, sustainable, and deeply rooted in nature’s rhythm. The body responds best not to pressure, but to patience. So, whether it's stepping outside for five minutes, skipping one extra reel on the phone, or sleeping before the clock hits eleven, these small acts carry the weight of something much larger: a heart that feels seen, supported, and safe.
