Think You're Getting Enough Sleep? 4 Symptoms Say Otherwise
How it's linked to sleep: Experts aren't exactly sure why being chronically low on sleep (generally defined as getting less than 7 hours per night) causes such deficits, but it could be due to communication breakdowns between the neurons and synapses that relay information, says Nancy Foldvary-Schaefer, DO, MS, director of the Sleep Center at the Cleveland Clinic. You may also find yourself unable to recall where you know someone from (work? the gym? the DMV?) or tripping over your words.
Keep in mind: Stress or neurological issues can also trigger memory blips. Make an appointment with your doctor if sleep-schedule adjustments or stress-reduction techniques don't help.
