Are your sleep habits affecting your risk of heart disease? Here’s what to know


We all know how important sleep is for staying healthy, but did you ever think about how your sleep habits might be affecting your heart? It is true. Poor sleep can raise your risk of heart disease. Want to understand how sleep impacts your heart? Well, a study published in the Journal of the American Heart Association found that adults who sleep less than six hours a night have a higher risk of cardiovascular events compared to those who get seven to eight hours of sleep.

The Importance of Sleep for Heart Health

Getting a good night’s sleep is really important for keeping your heart healthy. During sleep, your body performs crucial tasks that repair and maintain your cardiovascular system. When you do not get enough sleep or the quality of your sleep is poor, these processes get disrupted, putting extra stress on your heart.

How Poor Sleep Affects Heart Health?

  • Increased Blood Pressure

When you do not get enough sleep, your blood pressure stays higher for longer periods. The American Heart Association notes that during normal sleep, blood pressure naturally decreases. Without enough sleep, this does not happen, leading to consistently high blood pressure, which is a major risk factor for heart disease and stroke.

  • Inflammation

Lack of sleep can lead to inflammation in your body. Chronic inflammation is linked to a variety of heart conditions, including atherosclerosis, where the arteries become narrowed or blocked. A study in Circulation found that sleep deprivation triggers inflammatory processes.

  • Obesity

Not getting enough sleep can mess with the hormones that control hunger, making you more likely to overeat and gain weight. Obesity is another major risk factor for heart disease. According to the Sleep Foundation, poor sleep increases ghrelin (the hunger hormone) and decreases leptin (the hormone that tells you when you are full).

  • Insulin Resistance

Poor sleep can make your body less responsive to insulin, increasing your risk of type 2 diabetes, which is closely linked to heart disease. Research in The Lancet Diabetes & Endocrinology highlights that sleep restriction negatively impacts glucose metabolism and insulin sensitivity.

Recent research indicates that insomnia can significantly raise your risk of heart attack. According to a study, those with insomnia are 69% more likely to have a heart attack over a nine-year follow-up period than those without insomnia. “Insomnia should be considered a risk factor for developing a heart attack,” says Yomna E. Dean, a medical student at Alexandria University in Egypt. The study found that people who slept five hours or less per night had the highest risk, especially those with both insomnia and diabetes.

Signs Your Sleep Habits May Be Affecting Your Heart

  • Waking up frequently during the night
  • Snoring or gasping for air
  • Feeling tired even after a full night’s sleep
  • Trouble falling or staying asleep
  • Relying heavily on caffeine to stay awake during the day

Tips for Better Sleep and a Healthier Heart

Improving your sleep can help lower your risk of heart disease. Here are some practical tips:

  • Stick to a Sleep Schedule

Go to bed and wake up at the same time every day, even on weekends. This consistency helps regulate your body’s internal clock.

  • Create a Bedtime Routine

Establish a relaxing pre-sleep routine to signal to your body that it is time to wind down. This could include activities like reading, taking a warm bath, or practicing meditation.

  • Make Your Sleep Environment Comfortable

Make sure your bedroom is dark, quiet, and cool. Invest in a comfortable mattress and pillows to improve your sleep quality.

  • Limit Screen Time Before Bed

The blue light from phones, tablets, and computers can interfere with your sleep. Try to avoid screens at least an hour before bedtime.

  • Watch Your Diet

Avoid heavy meals, caffeine, and alcohol close to bedtime, as these can disrupt your sleep.

  • Get Regular Exercise

Regular physical activity can help you fall asleep faster and enjoy deeper sleep. Just make sure to finish exercising at least a few hours before bed.

  • Manage Stress

Chronic stress can interfere with your sleep. Practice stress-reducing techniques like deep breathing, yoga, or mindfulness.

When to see a doctor?

If you keep having trouble sleeping or think you might have a sleep disorder, it’s a good idea to see a doctor. They can figure out what’s going on and suggest ways to help you sleep better. Getting help early can make you feel better and keep your heart healthy too.

How well you sleep is really important for your health and can even impact your risk of heart disease. By focusing on good sleep habits and getting help for any sleep problems, you can take care of your heart and feel better overall. Remember, a good night’s sleep is one of the best things you can do for your heart!
