If our patients are not getting enough sleep, it can lead to health problems. According to a recent study published in the Journal of the American College of Cardiology, there is a potential link between getting 6 hours of sleep a night and atherosclerotic lesions–the buildup of cholesterol in the wall of your blood vessel–in different blood vessels of the body.
This buildup can keep growing larger, progressively narrowing the vessel. Picture reducing a four lane highway to three, two, one or even no lanes. That is what happens to blood vessels when patients get 6 hours of sleep or less a night.
What happens to the blood vessel?
When the blood vessel gets too narrow, it can no longer provide enough blood and oxygen to whatever parts of the body depend on the blood vessel. This might be your heart, your brain, your kidney or any other part of your body. Plaque can also break off and travel through your bloodstream, which can continue to cause further harm to your health and well-being.
There is a growing body of evidence that less and worse sleep could increase your risk of cardiovascular disease. When you sleep, that is the time for your body to heal and restore itself, which can include fixing the damage in your blood vessel walls.
How this factors in with sleep
The researchers used statistical analysis to determine if there was an association between sleep length or quality, and the presence of atherosclerotic lesions. The results were not good for those individuals who only sleep for a short period of time.
For those who got less than six hours of sleep a night were 27 percent more likely to have atherosclerotic lesions in various arteries than those who got seven to eight hours of sleep a night. The 20 percent with the worst quality of sleep were those who woke up the most and had the most movement in their sleep. These individuals were 34 percent more likely to have atherosclerosis compared to others who got better sleep.
It is important that we help our patients get a better night’s sleep to ensure their overall health and well-being.
