Sometimes memory loss can be funny.
Have you ever gone to school or work in your house shoes because you were too sleepy to remember to change shoes? Have you locked yourself out of your home because you were still groggy from lack of restful sleep only to remember (too late) that your house and car keys were still lying on the kitchen table? Have you put your sunglasses atop your head, then searched frantically for them because you forgot? One cause of memory loss is from sleep deprivation.
Memory loss can be dangerous.
Sometimes it will prove lethal, sometimes just unfortunate.
The sleep deprived will suffer memory loss as though in a brain fog, walking around in a daze, unable to focus, sometimes with a blank expression.
Worse cases of memory loss from sleep deprivation would be to forget medication you'd already taken, taking it again and suffering severe side effects, possibly becoming hospitalized as a result.
If you became too sleepy to remember to turn off a burner on a stove, it could cause a house fire, possibly injuring some children you left home alone or an elderly person in your care.
Memory loss is caused by other things besides sleep deprivation, of course.
But the most important thing is to find ways to remedy the problem.
Take advantage of a short nap whenever possible.
Learn to relax before its time for bed, instead of waiting on bedtime to begin relaxing.
For the chronic work-a-holic, the new parents, or a college student burning the candle at both ends, learning to get the proper amount of sleep is essential to avoiding unfortunate events caused by sleep-deprived memory loss.
Remember, if you don't care for your body and mind, it can't continue to function properly.
