Sleep Refreshes by 'Resetting' your brain cells

We all know that sleep is a necessary part of our existence but when people suggest that sleep ‘refreshes’ us, what exactly does this mean?

A new study by the team at the National Health and Development in Maryland USA suggests that during sleep neural signals travel in reverse, as the signals travel in reverse it acts as a form of ‘editing’.

These kinds of signals act as a way of refreshing the brain and a way for the brain to contemplate and store memories.

The over saturation of brain cells that occurs in times of sleep deprivation make it increasingly difficult to receive and process new information.

Sleep acts as a sort of tune-up for your brain, this is the reason that many of us are able to make better decisions after a sound night’s sleep.

From a practical perspective, just imagine the feeling you have when you work in to the early hours of the morning, your brain often feels bogged down with information, this is because your brain has been overloaded with information and needs rest to be able to process and store these memories. This is why it may feel as though information isn’t settling in, because your brain has already reached its metaphorical full capacity for the day.

The study contains a neurological explanation for the refreshing feeling we all have after a good night’s sleep. This is just one of many of the emerging studies that have appeared in recent weeks detailing the positive effects of a regular sleeping pattern, as well as the potential hazards associated with sleep deprivation.
