Infant Sleep Loss Linked to Brain Development Problems

New research shows that sleep deprivation during early development disrupts brain function, impacting neuron growth and synapse formation. The study found that young mice lacking sleep did not experience the “sleep rebound” seen in adults, leading to lasting deficits in social behavior and memory.

A Consistent Lack of Sleep Negatively Impacts Immune Stem Cells, Increasing Risk of Inflammatory Disorders and Heart Disease

Sleep deprivation alters the structure of DNA inside immune cells and increases the number of immune cells, which causes them to overreact and spark inflammation. The study found catching up on sleep does not reverse this effect.
