… says that three nights of poor sleep can increase the risk of heart disease
Experts have warned that people with a bad dream for only three nights may have a greater risk of developing heart disease.
Researchers at the Uppsala University of Sweden found that even three nights for sleep deprivation, or approximately four hours per night, can alter the body and increase the risk of heart disease.
The study, which examined the speed with which the body can begin to react negatively to poor dream, involved 16 healthy young people who spent several days in a laboratory, where everything, from their meals to their levels of activity and exposure to light, was carefully controlled.
In a session, the participants sleep normal for three consecutive nights, while during the other session, only four hours every night sleep. During both sessions, blood and afternoon blood samples were taken after the high intensity exercise that lasted 30 minutes.
The researchers measured almost 90 different proteins in blood samples and discovered that the levels of many of them that are associated with greater inflammation increased when the participants were deprived of sleep.
Many of these proteins have already been related to a greater risk of cardiovascular diseases, such as heart failure and coronary artery disease, researchers said in the study published in the Biomarker Research magazine.
Sleep, nutrition and exercise are among the lifestyle factors that affect the health of the heart. A variety of factors, including nutrition and exercise, were regulated in the laboratory environment to isolate the effects of sleep.
According to the study published in the magazine Biomarker Research, “surprisingly, the changes occurred even in young and healthy adults and after only a few nights of bad dream.”
In addition, the exercise was not enough to completely cancel the damage caused by sleep restriction.
Jonathan Cedernaes, doctors and teachers at the University of Uppsala, who directed the study, declared: “With this study, we have improved our understanding of what role the amount of sleep we receive in cardiovascular health.
The study authors emphasized that more research is needed to determine the impacts that sleep restriction can have in the short term and women.
