In order to have good health you are advised to have enough sleep. Some diseases come about as a result of lack of enough sleep. Cardiovascular disease is among the health problems that occur due to insufficient sleep. Therefore, it means sleep reduces cardiovascular diseases.
According to a study by Massachusetts General Hospital (MGH), they discovered that sleep helps the occurrence of atherosclerosis. Atherosclerosis, is a cardiovascular disease where the arteries become narrowed and hardened disrupting the flow of blood due to build up of plaque.
An online publication Nature at Massachusetts General Hospital MGH, gives information on the discovery of how sleep deprivation can leads to excessive production of white blood cells which in turn leads to atherosclerosis. A report by Filip Swirski, PHD of the MGH Centre who is also the senior author of Nature said that,it has been discovered that the production of inflammatory cells and the health of blood vessels in the bone marrow is usually regulated by sleep,This means that when a person lacks enough sleep, the production of inflammatory cells in interfered with causing inflammation in the body and development of cardiovascular diseases. Swirski further says that they have discovered that how a hormone found in the brain that controls being awake controls the production of inflammatory ells and blood vessels in the bone marrow hence protecting against cardiovascular disease.
To illustrate how sleep reduces cardiovascular diseases or rather atherosclerosis, his team used a genetically programmed mice to develop atherosclerosis and subjected it to interrupted sessions of sleep. This acted as a situation in human life where a person lacks sleep due to some interruptions of like noise.This experiment was conducted alongside other animals of same strains which were aloud to sleep with no forced interruptions. Results from the animals that were subjected to sleep interruptions they developed arterial plaques which is a contributing symptom to atherosclerosis.
A further result from the experiment showed that the sleep deprived mouse had an excessive production of white blood cells in the bone marrow. Additionally, it had very low levels of hypocretin. Hypocretin is a hormone produced in the brain and helps in regulating the brain. The MGH team discovered that hypocretin regulates the production of white blood cells.
In conclusion, according to Swirski, hypocretin helps reduce diseases caused by lack of sleep.He says their is a need to conduct further studies on how sleep reduces cardiovascular diseases and research on neuro-immune axis which has been discovered recently.
