Can Lack of Sleep Affect My Heart Health?

February is American Heart Month, a federally designated event since 1964. Throughout the month, the American Heart Association concentrates on reminding us to focus on the health of our hearts. Even if your heart is healthy, you probably know someone affected by cardiovascular disease – it leads to the deaths of approximately 2,300 Americans every day. This number does not have to be so large. Preventing heart disease comes down to making heart-healthy choices with respect to diet and lifestyle. The right lifestyle decisions can lower your risk for developing heart disease by as much as 80%.

Americans Don’t Get Enough Sleep

Overworked Americans lead busy lives, and many find it hard to get enough sleep. In fact, the duration of sleep has decreased by 1.5 – 2 hours per night per person over the last 50 years. Not enough sleep is defined as less than six hours per night. While shortened sleep itself won’t give you a heart attack, it will increase the risk factors for heart disease. So, it’s pretty sound advice that sleeping less than six hours a night is not good for you.

How Lack of Sleep Can Affect Your Heart

Sleep deprivation puts people of all ages at a greater risk for coronary heart disease and cardiovascular disease. You may believe that your heart is in good shape because your weight is under control, you’re a non-smoker and you exercise regularly. But, while all of these factors help lower your chances of developing heart disease, lack of sufficient sleep is detrimental to heart health, and if you don’t get enough sleep you need to do something about it. Here’s some information on how sleep affects your heart.

  • A healthy heart needs sleep. During a good night’s sleep, both your heart rate and blood pressure go down giving your hard-working heart a rest. Shortened sleep is not long enough for this essential lowering to take place and may eventually lead to higher daytime blood pressure.
  • People with sleep deprivation have a heart rate that stays elevated. It’s as if the sleeper has a high stress level.
  • Shortened sleep disrupts the metabolism of glucose and can lead to increased insulin resistance, a risk factor for both heart disease and type 2 diabetes.
  • Not enough sleep can produce an increase in C-reactive protein (CRP) which is released when inflammation and/or stress are present.
  • Studies have found a link between shortened sleep and increased calcium deposits in coronary arteries.

Young People Are at Risk Too

Research shows that too little sleep early in life can lead to a snowballing of heart-related problems in adulthood. For instance, one study found that adolescents with a history of not sleeping well tended to test high on the body mass index, and to have elevated cholesterol levels and high blood pressure.

Sleep Apnea

Sufferers from sleep apnea, a condition where sufferers frequently wake up during the night, are known to have compromised heart health. Much research has been done to confirm the relationship between sleep apnea and cardiovascular disease. One study found that over a period of eight years, men suffering from severe sleep apnea had a 58% higher chance of developing congestive heart failure than those without this breathing disorder.

"I was especially impressed with Andrew the Respiratory Therapist who reviewed my study with me and answered my questions. Andrew thoroughly explained everything about the Cpap machine-from start to finish. I never felt rushed and was assured I could contact him with any additional questions or needs. Andrew told me he would follow up with a call in a week and he did. I believe this center performed the study appropriately and the added benefit of having Andrew teach me about the machine and what to expect was a bonus."

"I recommend them highly!! I took my 2 year old daughter for a sleep study and was very impressed. Our sleep technician was amazing with her, very patient and kind. The DVD we brought to watch while getting her hooked up got stuck in the TV and they vowed to return it. We got a call the next day checking on our daughter and saying how sweet she was, they mentioned the DVD. Several days later, we received the DVD plus a new copy of the Lion King with a nice note. They are very good at what they do and if they can make a 2 year old feel at ease, they can probably do the same with anyone!!"
