New research suggests that the way people breathe during sleep may have a direct impact on heart health. The study, published in a scientific journal, examines the link between obstructive sleep apnea and cardiovascular disease.
Obstructive sleep apnea is a condition where breathing repeatedly stops and starts during sleep. The research indicates that disrupted sleep patterns do more than affect energy levels. They can also increase the risk of both sleep apnea and heart disease.
When breathing is compromised during sleep, the body responds with inflammation, oxidative stress, and changes in how cells sense and respond to oxygen. The study points to the circadian rhythm as a central factor in this process.
Patients with sleep apnea often show abnormal daily patterns in blood pressure, heart rate, melatonin production, and cortisol levels. The research also found that intermittent drops in oxygen during sleep can alter the expression of core clock genes in heart and lung tissue within hours.
Chronotherapy, which means aligning treatments with the body’s natural rhythms, shows promise as a way to reduce both sleep apnea and cardiovascular risks. The study highlights the importance of the body’s natural sleep-wake cycle for heart health.
People spend about one-third of their lives sleeping, yet many do not think about their breathing during rest. Experts recommend several steps to support healthy nighttime breathing. These include keeping consistent sleep and wake times, creating a cool and dark sleep environment, and managing evening stress through breathwork or meditation.
Sleeping on the side rather than the back can help keep airways open. Consulting a healthcare provider is advised for those who experience snoring, gasping, or suspect breathing issues during sleep. Some research also suggests that magnesium supplementation before bed may support muscle relaxation and improve sleep quality.
The connection between sleep and heart health is well established. This new research adds detail on how breathing patterns and circadian rhythms interact. The findings suggest that attention to nightly breathing and support for healthy circadian rhythms may benefit the heart.
