Most people know that sleep is important for feeling rested and staying alert during the day. But what many don’t realize is that good sleep is also vital for a healthy heart.
Research shows that how well and how long you sleep each night can have a big impact on your heart health. In fact, not getting enough sleep or getting too much can raise your risk of heart disease, which is the leading cause of death around the world.
For most adults, the ideal amount of sleep is between 7 and 9 hours each night. When you sleep, your body enters different stages that help it rest and recover. During the deepest stages of sleep, your heart rate and blood pressure drop.
This is important because it gives your heart and blood vessels time to relax and repair. Think of it as a nightly “reset” that keeps your heart working well over time.
If you don’t get enough sleep, your body doesn’t get the chance to rest and recover. This can lead to several health problems that are linked to heart disease. For example, lack of sleep can raise your blood pressure. High blood pressure is one of the main risk factors for heart attacks and strokes.
It forces your heart to work harder than it should, which can cause damage over time. Not sleeping enough also increases the levels of stress hormones in your body, like cortisol and adrenaline. These hormones make your heart beat faster and your blood vessels tighten, which raises blood pressure even more.
People who don’t sleep well are also more likely to gain weight. This happens because sleep affects hormones that control hunger. When you are tired, your body makes more of the hormone that makes you feel hungry and less of the hormone that tells you when you are full. As a result, you may eat more than you need, leading to weight gain and increasing the risk of heart disease.
One of the biggest sleep-related risks to heart health is a condition called sleep apnea. Sleep apnea is when your breathing stops and starts repeatedly during sleep. These pauses can last for seconds or even longer, and they prevent you from getting the deep, restful sleep your body needs. People with sleep apnea often snore loudly and feel tired during the day, even after a full night’s sleep.
Sleep apnea is dangerous for your heart because every time you stop breathing, the oxygen level in your blood drops. This triggers your heart to work harder and raises your blood pressure. Over time, this can lead to serious heart problems like heart attacks, heart failure, and irregular heartbeats.
Another common sleep problem that affects heart health is insomnia. Insomnia means you have trouble falling asleep or staying asleep. When this happens regularly, your body doesn’t get the chance to lower its blood pressure during the night.
This constant pressure on your heart can lead to heart disease. People with chronic insomnia also tend to have higher levels of stress hormones, which can make heart problems worse over time.
Interestingly, the connection between sleep and heart health goes both ways. Just as poor sleep can harm your heart, having heart problems can also make it harder to sleep well.
For example, people with heart failure often wake up at night because of breathing problems, the need to go to the bathroom frequently, or discomfort in their chest. This creates a cycle where poor sleep makes heart problems worse, and heart problems make sleep worse.
The good news is that improving your sleep habits can also improve your heart health. There are simple steps you can take to get better sleep. Start by setting a regular sleep schedule, going to bed and waking up at the same time every day, even on weekends.
Create a sleep-friendly environment that is cool, dark, and quiet. Avoid caffeine and electronic screens like phones or tablets before bed because they can make it harder to fall asleep. Developing a relaxing bedtime routine, like reading a book or listening to calming music, can also help.
For people with sleep disorders like sleep apnea, treatments are available. One of the most common treatments is using a CPAP (Continuous Positive Airway Pressure) machine. This device helps keep your airways open while you sleep, making it easier to breathe and keeping your oxygen levels steady. There are also oral devices that can help with breathing if a CPAP machine is not suitable.
In summary, good sleep is not just important for feeling rested—it is also crucial for keeping your heart healthy. Poor sleep habits can lead to high blood pressure, weight gain, and even serious heart conditions like heart attacks and strokes.
Taking steps to improve your sleep can help protect your heart and lower your risk of heart disease. If you are struggling with sleep, it is a good idea to talk to your doctor. They can help you find ways to improve your sleep and, as a result, protect your heart.
