Signs You're Sleep Deprived

Sleep deprivation can affect the brain, too. According to a study by the National Academy of Sciences, attention span and short-term memory may be linked to sleep deprivation. Researchers found that sleep-deprived participants often had difficulty paying attention during the study — which led to issues with retaining information and short-term memory. Another study published in the journal Current Opinion in Neurology found that sleep deprivation also led to long-term memory problems.
