Sleep is a vitally important component to our health. A “good” night’s sleep is considered between 7-9 hours. However, there is lots of variability as to how different people function with less sleep. I am certain that if not you personally, you know a number of people that seem to function perfectly fine on less than 6 hours of sleep each night.
A recent study was released that demonstrated that even younger people that slept less than 7 hours per night had higher rates of heart disease than those people sleeping 7-9 hours. Why would sleep issues impact heart health? Here are some potentially contributing factors:
- Hypertenson
During normal sleep, blood pressure typically drops. However, with sleep problems, blood pressure can remain elevated for longer, which is a leading risk factor for heart disease and stroke.
- Diabetes Mellitus
A lack of sleep can disrupt hormones that regulate blood sugar, increasing the risk of developing type 2 diabetes. Diabetes can damage blood vessels and contribute to heart disease.
- Obesity
Sleep deprivation can disrupt hormones that regulate hunger and appetite, leading to weight gain and obesity. Obesity is a significant risk factor for heart disease.
- Inflammation
Sleep loss can trigger the release of inflammatory proteins in the body, which are linked to an increased risk of cardiovascular disease.
- Atrial Fibrillation
Studies have shown that poor sleep can increase the risk of atrial fibrillation, an irregular heartbeat that can lead to blood clots, heart failure, and stroke.
- Coronary Artery Disease
Individuals with severe sleep deprivation (5 hours or less) have a significantly higher risk of coronary artery disease, where arteries narrow and restrict blood flow to the heart.
- Congestive Heart Failure
Research has also linked sleep deprivation to an increased risk of heart failure, both with preserved and reduced ejection fraction.
There are MANY other negative health impacts caused by not getting enough sleep aside from heart issues. Get that rest! The Sandman is a mythical character originating in Germanic and Scandinavian folklore who puts people to sleep and encourages and inspires beautiful dreams.
