Lack of sleep and its poor quality can negatively affect not only the mood of a person, but also on his health – in particular, on the state of his cardiovascular system. And although evidence of this relationship has been found for quite some time, some of the points associated with it have eluded so far. However, thanks to a comprehensive study of specialists from Harvard University, it became possible to take a more accurate and detailed look at the process that results from poor sleep quality and which affects the functioning of the heart. In particular, specialists focused on identifying specific chemical agents that begin to work when lack of sleep.
Consistent with the previous research database and armed with some additional information regarding the proven relationship, Harvard experts focused on identifying those chemical compounds and changes that occur with the cardiovascular system when a person is not sleeping well or long enough. They found that lack of sleep leads to a significant increase in the number of white blood cells that can cause clogging of the arteries – and this process is based on the action of hypocretin, a special protein that pushes blood bodies to increase the production of another protein called CSF-1.
But an increase in the amount of this protein just leads to an increase in the number of white blood cells, which makes the arteries more rigid and unyielding for the passage of the required amount of blood. As a result, a person with a high degree of probability begins to experience various symptoms of a developing cardiovascular disease – the same research results were achieved on experimental mice.
Nevertheless, experts note that most likely some other organic compounds are also involved in this process, which are somehow responsible for the manifestation of such a process. It is worth noting that despite many third-party aspects, the results of the current research experiment are very clear in clarifying the real risks of developing cardiovascular diseases from lack of sleep.
