We are never really sure as to how much sleep is actually a balanced sleep. The healthy sleep requirement typically varies anywhere between 8 hours and 10 hours, based on the individual. Sometimes, even a fitful 6 hour sleep also compensates and elevates one’s well being. The new study says that there is a line to be drawn between what is termed as ‘over sleep’ and what is accounted for as an ‘undersleep’.
According to the new study by an author from the Norwegian University, sleep duration actually impacts the well being of heart. Anything between enough and adequate sleep ensures better heart and lifestyle, while too much or too less causes coronary heart diseases in the long run. This includes even the heart attacks.
Lead author Linn Beate affirms that sleep duration and sleep cycle directly affects the heart condition in people.
These findings are based on a total of 392,164 Taiwanese adults who were given a health check between the years 1998 and 2011. They were all asked how long they usually slept at night in course of consultations.
During the follow up period a total of 711 of these individuals died of cardiovascular diseases.
Healthy Sleep Cycle Confirmed – 6 to 8 Hours
The final analysis showed that those who slept for less than 4 hours a night were 50% more likely to develop heart related ailments as compared with the participants who slept between 6 and 8 hours.
In addition, those who slept more than 8 hours a night also had a 53% higher risk of dying from heart disease as compared to the participants who slept between 6 and 8 hours every night.
There was no increased risk associated with sleeping between 4 and 6 hours a night as compared to sleeping between six and eight hours.
Once other factors were duly taken into consideration, the risk was still 28% higher.
