New research suggests that the way a person breathes during sleep could have a direct impact on their heart health. The study focuses on the connection between sleep-disordered breathing and cardiovascular disease.
Sleep and heart health have long been linked, but a recent study published in the Journal of Molecular and Cellular Cardiology examines how breathing patterns during sleep, specifically in cases of obstructive sleep apnea (OSA), affect the heart. OSA is a condition where a person’s breathing repeatedly stops and starts during sleep.
Researchers found that disrupted sleep patterns do more than just affect energy levels. They can increase the risk of both sleep apnea and heart disease. When breathing is compromised during sleep, it triggers a series of biological responses. These include inflammation, oxidative stress, and changes in how cells sense and respond to oxygen.
The body’s internal clock, or circadian rhythm, plays a central role in this process. Patients with OSA often show abnormal circadian patterns in key markers such as 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 just a few hours.
Chronotherapy Shows Promise
Chronotherapy, which involves aligning treatments with the body’s natural rhythms, is showing promise as a way to reduce both sleep apnea and cardiovascular risks. This approach could help manage the condition by working with the body’s internal clock rather than against it.
Experts emphasize that supporting healthy nighttime breathing and circadian rhythms is important for cardiovascular health. Simple habits can make a difference. Sticking to consistent sleep and wake times, even on weekends, helps reinforce the body’s natural clock. Creating a sleep environment that is cool, dark, and quiet promotes deep, uninterrupted rest.
Magnesium supplementation before bed may help support muscle relaxation, including the muscles in the airway, and can improve sleep quality. Managing evening stress through breathwork, gentle stretching, or meditation can prevent circadian disruption. Sleeping on the side rather than the back can help keep airways open during the night.
People who experience snoring, gasping, or suspect they have breathing issues during sleep are advised to speak with a healthcare provider. The study underscores that heart health is not only about diet and exercise but also about how a person breathes and sleeps.
