Catching up on sleep over the weekend may reduce the risk of heart disease by nearly 20%, according to a new study. Sleep deprivation, defined as less than 7 hours a night, can lead to various health issues that may increase the risk of cardiovascular problems. While compensatory sleep may have some benefits, experts caution that it may not be a sustainable solution for individuals with chronic sleep deprivation.
The study, conducted by researchers from the State Key Laboratory of Infectious Disease in China, utilized self-reported data from over 90,000 participants in the UK Biobank project. Four cohorts were created based on the amount of compensatory sleep individuals had. The study found that those with the most compensatory sleep were 19% less likely to develop heart disease compared to those with the least amount of compensatory sleep. The CDC recommends adults get at least 7 hours of sleep per night, but 1 in 3 adults do not meet this requirement.
Dr. Rigved Tadwalkar, a board-certified cardiologist, was surprised by the study’s findings on the benefits of catching up on sleep. He emphasized the importance of prioritizing sleep for overall health, especially in relation to heart health. However, Melanie Murphy Richter, a registered dietitian nutritionist, noted that consistent lack of sleep can lead to stress hormone buildup, metabolic imbalances, and increased inflammation, contributing to serious health issues. She advised maintaining a regular sleep schedule and focusing on sleep quality as much as quantity for optimal health.
Sleep plays a crucial role in heart health by helping the heart vessels heal and regulate blood pressure, sugar levels, and inflammation control. Sleep deprivation can disrupt the body’s circadian rhythm, affecting hormone regulation and potentially increasing cardiovascular risks. Chronic sleep deprivation can lead to elevated stress hormones like cortisol, which may contribute to heart problems. Compensatory sleep can help lower stress hormone levels and normalize blood pressure and heart rate.
While naps during the day can provide energy boosts, consistent uninterrupted nighttime sleep is essential for the body’s most restorative processes. Nutrition also plays a significant role in establishing consistent sleep patterns, with hydration and supplements like melatonin and magnesium considered helpful. Whole-food sources like leafy greens, nuts, and seeds can provide sleep-supportive nutrients along with fiber and antioxidants. It is important to consult with a doctor before starting any supplements to ensure safety and effectiveness. Prioritizing sleep quality and quantity is essential for overall physical and mental health, especially in relation to heart disease prevention.
