Even Small Health Habits May Protect Your Heart

Small Wins: It’s easy to think about healthy living as a binary — you’re either doing it, or you’re not. But the truth is that it’s more like a sliding scale. Even small changes can add up. Case in point: a recent study found that adding just a few more minutes of sleep and exercise — and a few more vegetables to your plate — could significantly lower the risk of heart attack or stroke.

The Study: Researchers analyzed data from 53,242 adults in the UK Biobank. Participants wore wearable trackers to measure sleep and physical activity, and self-reported their diets, which researchers then scored. After an eight-year follow-up, participants who averaged just 11 more minutes of sleep, five more minutes of exercise, and one-quarter cup more vegetables per day had a 10% lower risk of cardiovascular events.

The Takeaway: Sleep, physical activity, and nutrition (SPAN) are major drivers of cardiovascular health. While even small increases appear beneficial, researchers found the most protective combination was eight to nine hours of sleep per night, about 42 minutes of moderate-to-vigorous physical activity per day, and a moderate diet quality score. Participants with this SPAN profile had a 57% lower risk of major cardiovascular events compared to those with the least optimal habits.

Keep in Mind: The study was observational, meaning it can show an association but cannot prove that these habits directly caused the reduced risk.
