Sleep is for the birds
I wanted to
title this “Mom’s a bird brain,” but I didn’t want to think I was poking fun at
myself or any other mothers. The truth is, as I recently learned, having a bird
brain when it comes to sleep is pretty great. And no, a little bird didn’t tell
me this.
Some birds
travel long distances on their migration routes, and others just fly around and
around and around and never really touch down. Scientists wondered how an
animal could be active so long without getting much rest. (I’m assuming these
scientists never really had multiple toddlers at the same time.) To make a long
and interesting story short, they found that birds actually sleep mid-flight,
in very short bursts, and here’s my favorite part, by only shutting down half
of their brain at a time.
The recent
study, which comes out of the Max Planck Institute of Ornithology in Germany
studied the frigatebird in the Galapagos Islands, which doesn’t sound like a
bad place to set up a science experiment if you ask me. They caught these birds
that are well known for never stopping, and placed teeny tiny EEG’s in their
skulls to monitor brain activity. The results showed that the birds sleep for
only 10 seconds at a time for a totally of 45 minutes a day. All of this
happens while in flight.
The birds
aren’t “sleep-flying,” either. By only sleeping with half of their brain, they
maintain some form of vigilance to make sure they don’t crash into each other
or fall in the ocean, because they can’t swim.
I’ve never
seen one of these birds, but I sure do feel like one.
Parenting,
or at least good parenting, never stops. Checking homework, making food,
driving to here and there, worrying about what they are doing, making sure
everyone is safe and happy and healthy. I’m not flying, but I sure feel like
life never really stops and like the frigatebird, I have mastered the art of
the power nap. (I prefer 12 minutes instead of 10 seconds.)
Not only that, but my brain
literally never stops thinking about what I need to be, or should be, doing.
I’m sure I’m not the only mother who wakes up in the middle of the night
worrying about her kids or can sleep through a storm but hears a baby’s cough
and springs out of bed like it’s on fire.
Like some of these sleeping birds,
there is another study that suggests that humans have a little of this
half-sleep brain, too, that we don't fully shut down so that we can be on guard
and don’t sleep so well when we are in a strange place like hotel or listening
for something. I’ll project that idea onto myself and why I haven’t gotten a
decent night of sleep in over fifteen years, bird brain that I am.
