Sleeping more on weekends may cut heart disease risk by up to 20%, study finds
- “Catching up” on sleep over the weekend could reduce the risk of heart disease by 20%, a new study suggests.
- Sleep deprivation — often defined as less than 7 hours a night — can present a host of health problems that lead to cardiovascular issues.
- Some experts caution that compensatory sleep may not be a sustainable plan for people with regular sleep deprivation.
“Catching up” on sleep over the weekend could reduce the risk of heart diseaseby nearly 20%, according to a new study presented this week by authors from the State Key Laboratory of Infectious Disease in China.
Using self-reported data from more than 90,000 people who participated in the UK Biobank project, researchers created four cohorts ranging from those with the “most compensated” amounts of sleep to those with the least. Sleep deprivation was defined as less than seven hours per night.
The median follow-up for subjects in this project was 14 years, and by analyzing hospital records and death registries, the study authors found that those with the most compensatory amounts of sleep were 19% less likely to develop heart disease than those with the least amounts.
Sleep deprivation can affect a person’s immune system, well-being, and ability to focus on daily tasks. The Centers for Disease Control and Prevention (CDC) recommends that adults get at least 7 hours each night but estimates that 1 in 3 adults do not get enough sleep.
Rigved Tadwalkar, MD, a board certified consultative cardiologist at Providence Saint John’s Health Center in Santa Monica, CA, who was not involved in the study, told GMHCN that he was surprised at the findings:GMHCN also spoke with Melanie Murphy Richter, MS, RDN, a registered dietitian nutritionist and the director of communications for the nutrition company Prolon, who was not involved in the study. Richter told GMHCN that while compensatory sleep—catching up on weekends, as the new study suggests—can be helpful in the short term, it’s not an approach for optimal mental and physical health.
Sleep helps the heart vessels heal and rebuild and affects processes that maintain blood pressure, sugar levels, and inflammation control. Too little sleep may increase the risk of cardiovascular disease.
Tadwalkar said that sleep deprivation can disrupt the body’s natural circadian rhythm, which in turn can affect the production of hormones that help regulate blood sugar levels. This can lead to insulin resistance and other cardiovascular risks.
“Sleep deprivation can elevate stress hormones like cortisol, which can contribute to heart problems. Catching up on sleep can help lower these levels. Chronic sleep deprivation can additionally lead to elevated blood pressure and heart rate. Compensatory sleep can help normalize these vital signs,” Tadwalkar said. “Sleep is also known to be key for a healthy immune system. Adequate sleep can help your body better fight off infections and inflammation, which is linked to heart disease.”
Richter said that naps during the day can be a valuable tool for energy boosts but are not a sustainable way to make up for sleep:
She added that nutrition can play a crucial role in establishing consistent sleep patterns, with hydration and herbs and adaptogens like chamomile, valerian root, passionflower, and ashwagandha considered helpful supplements. If you are thinking of using supplements, seek advice and clearance from your doctor before starting.
“When it comes to sleep, nutrition plays a crucial role that’s often overlooked. Melatonin supplements can help, particularly with jet lag or shift work, but it’s essential to get the timing and dosage right, as too much can disrupt your sleep. Magnesium is another key player, supporting relaxation by calming the nervous system,” Richter said. “But don’t forget about whole-food sources like leafy greens, nuts, and seeds, which offer sleep-supportive nutrients along with fiber and antioxidants, making them easier on your digestive system and more sustainable in the long run.”
