If you do not get enough sleep, you will eventually raise the risk of heart disease. A new study has shown why an awful night sleep is very bad for your heart and your blood vessels. The study was conducted in mice, and it has found that sleeping in cycles will change the levels of some certain hormones, thing that will lead to the production of inflammatory cells in the bone marrow. The inflammation has a huge role in the development of atherosclerosis.
The results were published in the journal called Nature, and it suggests that a good sleep will protect you against atherosclerosis, and a disrupted sleep will do worse. But because the results are based on mice and not on people, they still need confirmation when it comes to human beings.
What has sleep to do with the heart?
There are many studies that have shown that not getting enough sleep leads to increased risk of heart problems, like high blood pressure, or even worse, heart attacks and strokes.
In the new study, researchers have taken a look at mice that were already prone to atherosclerosis by genetics. Some of the mice were left alone to sleep sufficiently, others were disrupted, by being moved across the bottom of the cage. Those mice that didn’t get enough sleep had the normal weight, and the cholesterol levels were also okay if we are to compare them to those mice that slept well. However, those mice that didn’t get enough sleep had larger plaques in their arteries and a much higher level of inflammation in their blood vessels, if we are to compare them to those mice that slept well. Those that didn’t sleep good also had lower levels of a specific hormone, which is called hypocretin (also known as orexin) in their hypothalamus.
