Elephant sleeping habits

You may have heard that REM sleep is important for humans’ memory retention.  However, new research on elephants puts that theory into question.

In a previous post, I discussed how elephants have wonderful memories.  What I did not know was that wild elephants only sleep about two hours a day, and matriarchs sometimes will go without sleep for days!

Professor Paul Manger of the University of the Witwatersrand talked to BBC about the research.  Elephants likely go into dream sleep every 3-4 days.  They are the mammal that needs the least amount of sleep.

In comparison, humans on average should strive for 7-8 hours of sleep a night.

Elephants can be lured into sleep by a lullaby, however, as this video shows!
