Heart attacks are a leading cause of death worldwide, and occur when blood flow to the heart is partially or fully blocked. Though it can be fatal if not treated immediately, heart disease can be managed through medication and lifestyle changes. However, still it is imperative that you take all efforts to prevent a heart condition in the first place. While exercise and lifestyle changes do help, do you know that the day time naps you love so much too, can help prevent a heart condition? Yes, that is true! Let’s see how…Why heart health is so importantThe heart is a vital organ that pumps blood carrying oxygen and nutrients to the entire body. When blood flow to the heart is blocked, usually by a clot or fatty deposits in arteries, it causes a heart attack. To prevent heart attacks, one must keep their stress levels and blood pressure under control.
How is napping helpfulWhen we are stressed or sleep-deprived, our bodies produce more stress hormones like cortisol. High cortisol levels increase blood pressure and inflammation, both of which damage the heart and blood vessels over time. Daytime naps help reduce these stress hormones, allowing the heart to rest and recover.Studies have found that people who take short naps regularly, have lower blood pressure and less risk of heart disease. Napping improves the balance of the autonomic nervous system, which controls heart rate and blood pressure, by increasing the activity of the parasympathetic nervous system—the “rest and digest” system that calms the body.How long should a nap beThe key to heart-healthy naps is keeping them brief—usually between 12 and 30 minutes, and no longer than 40 minutes. These short naps are long enough to reduce stress and improve alertness but short enough to avoid sleep inertia, which is the groggy feeling after waking from deep sleep.Naps longer than 40 minutes can lead to deeper sleep stages and make waking up harder, sometimes causing confusion or tiredness. Brief naps, sometimes called “power naps,” refresh the brain and body quickly and have been linked to better heart health.Benefits of day time napsLow bpShort naps help reduce blood pressure by relaxing blood vessels and lowering stress hormone levels. High blood pressure is a major risk factor for heart attacks, so keeping it in check is crucial.Reduced stressNapping lowers cortisol and other stress hormones, reducing the strain on the heart. Chronic stress increases the risk of heart disease, so managing stress is vital.
Improved heart rate variability:Heart rate variability (HRV) is a measure of how well the heart adapts to stress. Higher HRV means better heart health. Brief naps increase HRV by activating the parasympathetic nervous system.Better nighttime sleepShort naps can improve overall sleep quality by reducing the sleep debt accumulated during the day. Good nighttime sleep is essential for heart health.Who can benefit the mostPeople with high blood pressure, chronic stress, or a family history of heart disease may benefit the most from incorporating brief naps into their daily routine. Shift workers and those with irregular sleep schedules can also use naps to reduce heart risks caused by poor sleep.What science saysSeveral studies support the heart benefits of daytime naps. For example, research in Mediterranean countries where napping is common shows lower rates of heart disease and stroke. A study published in the Archives of Internal Medicine found that people who napped regularly had a 37% lower risk of heart-related death compared to those who didn’t nap.Another study showed that even a 10-minute nap can reduce blood pressure and improve heart rate variability, indicating immediate benefits for heart function.Not a substitute for nighttime sleepWhile naps are helpful, they cannot replace a full night of restful sleep. Adults generally need 7-9 hours of sleep per night for optimal health. Naps are a supplement to good sleep habits, not a replacement.Sources:Archives of Internal Medicine, 2007.
