Those late nights may have a greater impact on your body than just a following day of yawning and reduced work output. According to Science of Us, researchers found that people who were routinely sleep depraved were more prone to brain a decline in brain volume.
They had their study published in Neurology, and it compared two MRI brain scans of 147 adults.
Study participants also completed a survey about their sleep habits. Those who had sub-par sleep patterns had brain shrinkage in multiple regions, though the study didn’t specify whether the loss was caused by lost sleep or if the lost sleep was brought on by the brain shrinkage.
The best thing is to still get at least seven hours of sleep a night.
