A new study has discovered that too much sleep can double up person’s death risk. The researchers have revealed that sleeping too much can also be harmful, as lack of sleep doubles a person’s death risk from heart disease.
The researchers group from the
The scientists also studied the other possible factors including age, sex, marital status, employment grade, smoking status, physical activity, alcohol consumption, self-rated health, body mass index, blood pressure, cholesterol, and other possible physical ailments.
Once the group adjusted for these agents, they were capable of isolating the effect that changes in sleeping patterns over the period of 5-years had on death rates some 11 to 17 years later. Those who slash their sleeping time from seven hours to five hours or less faced up a 1.7-fold increased risk in death from all causes, and twice the increased risk of death from a cardiovascular problem in particular by 2004.

“Short sleep has been shown to be a risk factor for weight gain, hypertension and Type 2 diabetes sometimes leading to mortality, but in contrast to the short sleep-mortality association it appears that no potential mechanisms by which long sleep could be associated with increased mortality have yet been investigated. Some candidate causes for this include depression, low socio-economic status and cancer-related fatigue,” said Professor Cappuccio. “In terms of prevention, our findings indicate that consistently sleeping around 7 hours per night is optimal for health and a sustained reduction may predispose to ill-health,” he added.
