Jakarta - New research shows that both regular sleep deprivation and excessive sleep have health implications.
In a new study, researchers examined the effects of regular short sleep and longer sleep habits on human brain function.
According to a report in Medical Daily on Tuesday, the results of the new study show that lack of sleep is consistently associated with depression and brain shrinkage in emotional areas.
Meanwhile, sleeping too long on a regular basis, according to research results, could be an early warning sign of cognitive decline, Alzheimer's, or even schizophrenia.
"This study represents a paradigm shift in how we understand the relationship between sleep and health," said Professor Jianfeng Feng from the University of Warwick, who led the study.
He said that short sleep is often the underlying cause of health problems, while long sleep tends to reflect pre-existing conditions.
"These findings highlight the importance of personalized interventions to address the unique biological pathways of short and long sleepers," he said.
