Too Much Sleep Associated with Premature Death
We have all heard about the dangers of failing to get 7 to 8 hours of sleep a day. However, it was unknown whether sleeping too much can also be detrimental to health. Some may speculate that sleeping more enables the body to save more energy and regenerate cells, but recent scientific evidence runs counter to this assumption.

Alarming statistics
A team of researchers from Keele University has reported that sleeping for longer than the recommended seven to eight hours is associated with an increased risk of dying prematurely and can be considered a marker of such risk. They also suggested that doctors should ask their patients whether their sleeping patterns fall within the healthy range and advise to undergo exams if they do not. The investigators analyzed the data collected in the course of 74 projects in which over 3 mln people were enrolled. When they compared their self-reported sleep duration and outcomes, they found that sleeping for 10 hours–something which is seen in quite a lot of teenagers and adults if they are given such an opportunity–was associated with a 30% higher risk of dying prematurely, compared to those who dedicated only 8 hours to sleeping. Those who slept even more than that, namely longer than ten hours, were at an even greater risk: the risk of stroke was increased by 56%, and they were also 49% more likely to die from a cardiovascular disease.
Rise and shine
The takeaway is that maintaining quality sleep of 7 to 8 hours daily is an integral part of a healthy lifestyle. There are many factors which can force us to deviate from the recommended patterns, such as having irregular working hours or taking care of small children. However, there are contributors which are not that easy to spot, and one of them is amenities. In this day and age, we have electricity, water and all mod cons available round the clock. Since we have access to the activities which used to require daylight in the past at any time of the day, we are more likely to abuse it and stay up late watching another Game of Throne series. Try not to be like that. Sleeping for 7 to 8 hours is not only healthy on paper – it is something that can help you boost your performance and feel better.References:
