Every month academic journals, universities, and other publications release more evidence to readers that reveal we are more dependent on sleep than previously known. According to a study conducted at the University of Oslo in Norway, it was found that people with disrupted sleep had a decline in brain volume.
A study published in the Journal of Neuroscience found that staying awake too long is proven to kill brain cells in mice. This is one more study that reveals how important it is to get enough sleep each and every night.
Getting years of poor sleep can actually age your brain and slow its functioning. As always, more and more studies are revealing just how important it is to maintain a regular sleep pattern throughout your entire life. According to a recent study, poor quality sleep increases the risk of having impaired mental facilities by up to 50 percent, which is equivalent to a five-year increase in age.
There has been debate among medical professionals concerning why we actually need to sleep. It has been accepted that sleep rejuvenates the brain but the true purpose is not fully known. Scientists have studied sleep patterns in all types of animals, from flies to humans. Sleep is essential to consolidating memories and its major purpose may be to activate the brain’s cleaning crew.
