Sleeping less than 8 hours a day can harden your blood vessels and affect your heart.
You sleep a little thing? Reconsider changing your sleep habits, as new studies showed that with a single night you sleep less than four hours, you increase the risk of cardiovascular disease.
In an experiment in England, a group of people slept 8 hours one night, and less than 4 the next. The researchers tested the group and found their blood vessels were stiffer and breathing was irregular.
Although the connection is not entirely clear, the researchers believe that the brain with less hours of sleep signals the blood vessels to harden, said the head of the study, Shahrad Taheri.
In addition, breathing irregularly can cause apnea and therefore, heart problems.
Although occasionally stopping a good night’s sleep one or two nights is not synonymous with problems, the important thing is to recover normal sleep as soon as possible, because the study found that the circulatory system returned to normal after rest.
Although there is no definite time, researchers recommend 8 hours of sleep a day not only to keep you healthy, but to recover the wear and tear of time ago.
