The results of the study are stressful, given that almost every fourth adult works with transfers and regularly encounters a sleep regime violation.
Researchers from the University of Uppsal in Sweden have found that only three nights with limited sleep – about four hours a day – can cause blood changes associated with a high risk of cardiovascular disease, reports of Medical XPress.
During the study, scientists study inflammatory proteins in the blood -molecules that the body produces in response to stress or disease. If the level of these proteins remains high for a long time, it can damage the blood vessels and contribute to the development of heart failure, coronary heart disease and atrial fibrillation (heart rhythm disorder).
The study was attended by 16 healthy young men who spent many days in the laboratory under strict nutrition, physical activity and light exposure. Participants passed two modes: three nights of normal sleep (8.5 hours) and three nights with limited sleep (4.25 hours). After each season, they conducted a brief intensive training on an exercise bike, and their blood was taken for examination before and after loading.
Scientists measure nearly 90 different proteins in blood samples. It is noted that a lack of sleep has caused a pronounced increase in the level of inflammatory markers associated with heart disease. In addition, although physical exercises usually stimulate the production of proteins that support brain and heart functioning, these positive effects weaken after three nights of poor sleep.
The study also revealed that blood fence time: the protein level changed depending on whether it was morning or evening, especially in a lack of sleep. This indicates that sleep affects not only the composition of the blood, but also the day -to -day rhythm of the display of changes.
We remind you, earlier that scientists have discovered a major receptor to improve fast sleep.
