Sleeping less than nine hours a day leads to cognitive decline, mental problems, and less gray matter in brain regions, according to a new study. According to a study published in the journal Lancet Child & Adolescent Health, elementary school-age children who sleep less than nine hours a night have significant differences in certain brain regions responsible for memory, intelligence, and well-being compared to those who they sleep less than nine hours a night. the recommended nine to 12 hours of sleep per night, according to a new study led by researchers at the University of Maryland School of Medicine (UMSOM). Such differences were correlated with greater mental health problems, such as depression, anxiety and impulsive behaviors, in those who did not sleep. Inadequate sleep was also linked to cognitive difficulties with memory, problem solving and decision making. The findings were published today in the journal. The American Academy of Sleep Medicine recommends that children ages 6 to 12 get 9 to 12 hours of sleep a night on a regular basis to promote optimal health. Until now, no study has examined the lasting impact of sleep deprivation on the neurocognitive development of preadolescents.
