A growing body of research has identified modifiable lifestyle factors that can influence resting heart rate, a widely used indicator of cardiovascular efficiency and long-term health outcomes. Studies have found a causal relationship between lower resting heart rate and increased longevity, with exercise, sleep, and stress management identified as key factors in improving cardiovascular metrics.

Why it matters

Resting heart rate is a crucial indicator of overall cardiovascular health, and research shows that small changes in this metric can have significant impacts on mortality risk. By understanding the lifestyle factors that influence resting heart rate, individuals can take proactive steps to improve their long-term health outcomes.

The details

Recent studies have highlighted the benefits of resistance training, with nine weeks of strength training three times per week shown to reduce blood pressure and improve vascular function in middle-aged and older adults. Exercise more broadly, including increased daily movement and activity, has been consistently linked to improved cardiovascular metrics and reduced mortality risk. Sleep quality and stress management have also been identified as significant contributors, with chronic stress activating the sympathetic nervous system and poorer sleep associated with higher resting heart rates. Dietary factors such as hydration, electrolyte balance, and omega-3 fatty acid intake have also been shown to influence resting heart rate.

• In 2019, a review of genome-wide studies found a causal relationship between lower resting heart rate and increased longevity.
• In 2024, an analysis of data from the Paris Prospective, Whitehall, and Framingham studies showed that a 10-beat-per-minute increase in resting heart rate over five years was associated with a 20 percent higher risk of mortality.
• A 2024 study reported that nine weeks of strength training, performed three times per week, reduced blood pressure and improved vascular function in middle-aged and older adults.
• A 2014 study found that individuals reporting poorer sleep had higher resting heart rates, with stronger correlations observed as sleep quality declined.

What’s next

Researchers suggest that individuals focus on incorporating regular exercise, improving sleep quality, and managing stress levels as key strategies to lower their resting heart rate and support long-term cardiovascular health.
