There may be a lot more to a good night’s sleep than simply having a subjective feeling of being well rested. Cell Press reported via EurekAlert on Sept. 29, 2015, sleep may strengthen long-term memories which are in the immune system. Scientists believe that sleep may strengthen immunological memories of pathogens which have been previously encountered.
Over a century ago scientists demonstrated that sleep nurtures the retention of memories of many facts and events. Further studies have shown that slow-wave sleep, which is often referred to as deep sleep, is vital for helping to transform fragile memories which were recently formed into stable long-term memories. Senior author of this study Jan Born of the University of Tuebingen says it has long been known that in the psychological domain sleep supports long-term memory formation. It is now believed that sleep is important for long-term memory formation in all organismic systems. This research has been published in the Sept. 29, edition of the journal Trends in Neurosciences.
The immune system has been found to actually remember an encounter with a bacteria or virus via the collection of fragments from the bug which creates memory T cells. The memory of T cells can last for months or even years and helps the body with recognition of a previous infection so it can respond quickly. Studies in people have shown on the evenings after a vaccination increases in memory T cells are seen. These findings support the idea that slow-wave sleep contributes to the formation of long-term memories which enhance adaptive behavioral and immunological responses. What this means is that sleep deprivation could significantly undermine the well being of your mind and body.
Medical News Today reports that research has found that immunological memory is boosted by deep sleep. Scientists from the University of Tuebingen in Germany say they have discovered that deep sleep may strengthen both psychological and immunological memories. During the formation of psychological memory sleep has been found to be very important. The same seems to be true with immunological memory. Clearly sleeping well at night may benefit your well being in many very important ways.
