The study said, insufficient and restless sleep can result in impaired memory and judgement and can also lead to an increased risk of stroke, obesity, and cardiovascular disease.
"Sleep is even more multifaceted and fascinating than we realize," said Sigrid Veasey, Professor at the University of Pennsylvania.
"The findings reveal interesting new aspects of the complex relationship between sleep and the brain and the vital role that sleep plays in everyday human functioning," Veasey added.
For the study, the researchers analysed a micro-RNA expression that worked as an indicator for sleep loss in rats and humans. This led them to the conclusion that that the expression could play a key role in predicting those at the risk for diseases and cognitive deficits typically associated with sleep deprivation.
Memory retention could also be playing a key role in your sound sleep. The brain preferentially reactivates negative memories during sleep, prioritizing the retention of the emotional memories in particular, the study noted
Adequate sleep leads to improve cognitive function and enhance memory formation.
