Blog 126Brain Development and Sleep

Your child needs a healthy brain.  A healthy brain needs healthy sleep.

The brain is the only organ in the body that requires sleep for its healthy development and function.

A 2021 study of over 11,000 9-11-years-old children examined sleep duration, psychiatric problems, cognitive measures, and brain scans.  Here are some of their main findings:

• Short sleep duration is associated with more psychopathology.

• Short sleep duration is associated with specific regional decreases of brain volume.

• Long sleep duration is associated with higher cognitive scores.

• Long sleep duration is associated with specific regional increases of brain volume.

A 2022 study of over 8,000 9-10-year-olds divided them into two evenly matched groups:  

Those with sufficient sleep (SS) usually slept 9 or more hours each night.

Those with insufficient sleep (IS), who usually slept less than 9 hours each night.  

“We found that children who had insufficient sleep (IS) at the beginning of the study had less grey matter or smaller volume in certain areas of the brain responsible for attention, memory, and inhibitory control compared to those with healthy sleep habits (SS).  These differences persisted after two years, a concerning finding that suggests long term harm for those who do not get enough sleep.  These results provide evidence for the long-lasting effect of insufficient sleep on neurocognitive development in early adolescence.”

51. Speculation: Does Chronic and Severe Unhealthy Sleep in Childhood Cause Brain Damage? (2 of 2)

Sleep loss adversely effects pineal melatonin production which causes disturbance of circadian physiology of cells, organs, neurochemicals, neuroprotective and other metabolic functions. The most convincing evidence for permanent damage resulting from sleep loss comes from cellular studies in which animal experiments are indispensable.
