Study Links Sleep Deprivation to Slower Brain Function Due to Myelin Damage
A recent study has provided a biological explanation for the mental sluggishness experienced due to sleep deprivation. Researchers used human brain imaging and animal experiments to investigate changes in brain tissue when sleep is insufficient. The study focused on white matter, which consists of myelinated nerve fibers connecting different brain regions. Findings revealed that sleep deprivation leads to myelin damage, slowing down nerve signal transmission. This results in cognitive and motor impairments, affecting memory, attention, and coordination. The study highlights the importance of consistent, quality sleep for maintaining brain function.
