Sleeping well contributes to increase the benefit that a healthy lifestyle, which includes the practice of regular physical exercise, avoiding tobacco, a moderate consumption of alcohol, and following a balanced diet, has on the prevention of cardiovascular diseases (CVD) , according to the findings of a study that has been published in the 'European Journal of Preventive Cardiology'.
The research showed that adherence to these healthy lifestyles already reduced the risk of CVD up to 57%, but if these factors were also added 'enough sleep', that is, seven or more hours each night, the benefit of General protection increased even more, reaching 65% less risk of developing CVD, and up to 83% less risk of suffering a fatal cardiovascular event.
Taking into account only the duration of sleep, it was observed that the risk of developing a cardiovascular disease decreased by 22% in people who slept enough
In the study, called the Project of Surveillance of Risk Factors for Chronic Diseases (MORGEN), 6,672 men and 7,967 healthy young women participated at the beginning of the investigation, which were followed for a mean time of 12 years. The data corresponding to physical activity, alcohol and tobacco consumption, diet, and duration of sleep of the volunteers were recorded.
Attending only to the duration of sleep, the researchers observed that in people who slept enough the risk of developing a cardiovascular disease decreased by 22%, and that of fatal CVD by 43% compared with people with insufficient sleep.
The authors of the work have explained that sleeping a few hours had already been indicated as an independent risk factor to suffer CVD in previous studies, but these did not show the impact of quality sleep when added to the benefits provided by others four healthy life factors that have been included in this new study.
Regarding the number of hours of sleep that is considered sufficient, Monique Verschurem, of the National Institute of Public Health and Environment of the Netherlands, and principal investigator of the study, has stated that probably seven hours is enough for most people . However, and according to a previous study, also done by your group, people who sleep less than this time, but get up rested, do not increase their risk of cardiovascular disease.
