Lack of sleep affects the heart after just three nights
The study reveals that enough sleep can change blood proteins and increase heart risk Even in young and healthy people.

Three consecutive nights with low sleep can trigger blood molecular changes associated with cardiovascular disease. The University of Uppsala in Sweden is the same, which helps to explain how sleep deprivation affects the heart even in healthy and healthy people.
It is reported that sleep is associated with high risk of heart disease. Now, researchers at the University of Uppsala have been able to show more clearly AS Can cause damage to the molecular level.
No. New studyWere, and,, and,, and,, and,.. Researchers analyzed Inflammatory proteins in the blood. These are molecules that produce body when they are under stress or fighting a disease. When these proteins are too long, they can damage the blood vessels and increase the risk of problems such as heart failure, coronary disease and acupulor fibrillation (irregular heartbeat).
“Unfortunately, almost half of Sweden suffer from sleep disorders regularly, and it is very common in shift workers. Our goal is to detect mechanisms that explain how to increase enough sleep, and from there, find ways to interfere “, Said Jonathan SedernasDoctor and teacher in Uppsala who led the investigation.
Three sleepless nights are enough to influence the heart
There are 16 young and healthy men in this study, who are in the laboratory for several days, certainly controlled conditions: food, physical activity and light exposure are all monitored.
Each participants went through two steps:
- Three nights of normal sleep (About 8 hours);
- Sleep limited to three nights (4 hours and 15 minutes per night).
After each stage, volunteers exercised a small high intensity (cycling) and had blood analysis before and after training.
Changed inflammatory proteins with sleep deprivation
Researchers analyzed about 90 different proteins in blood samples. The result is clear: Sleep deprivation increased the levels of various inflammatory proteins Associated with cardiovascular disease.
Generally, physical exercise stimulates the production of beneficial substances to the brain and heart Interlusin -6 And the BDNF (Brain -dimensional neurotrophic factor). But after the sleepless nights, These answers are weakThe effect of sleep reveals that at least partially overlapping for the benefits of exercise.
Until blood analysis has an effect up to time
Another interesting aspect of the study is a variation of proteins throughout the day. The levels of some molecules are different in the morning and night-and these differences are more detected with reduced sleep.
Sleep deprivation is not only in the blood, but also These changes are the moment the more obvious day.
We all run the same losses
A data that surprises writers these changes that have taken place – Did not sleep just three nights to produce the effects measured in the bloodEven in young people and no health problems.
If it is taken into account One -third of the population works through shifts And that bad sleep is common in many modern daily routine, results are an important warning.
“Modern life invites us to exchange sleep for productivity, screen time or socialization. But the body will record everything – quietly and chemically – without concessions” summarizes Jonathan Sedernace.
