How Do You Get a Good Night's Sleep?
Sleep is something we all need, yet few of us get enough of it.
In addition to serving as a restorative time for our bodies, sleep appears to be vital to our brains.
During a full night's sleep, the brain experiences four or five rapid eye movement (REM) cycles, which are when most dreaming occurs.
Sleep researchers believe that during these REM cycles, the brain is busy doing maintenance work on itself - filing away new information and memories acquired since the last sleep, and rewiring and restoring its own synaptic structure.
Without adequate sleep, our moods, our ability to function, and our overall wellness are affected.
Before the advent of artificial light, our ancestors went to bed shortly after dark and slept until just before daylight.
Scientists think that during the longer winter nights, early humans also spent several hours in a semi-conscious, meditative state as part of their natural sleep cycle.
Unfortunately, modern 24-hour lifestyles don't allow for our natural circadian rhythms.
The average 21st century human seldom sleeps more than 6 or 7 hours per night - and many suffer from sleep disorders that keep them awake much of the time they're in bed.
What does it take to get a good night's sleep in the modern world?
That's what we're here to find out.
So slip into some cozy pajamas and slippers, pour yourself a cup of chamomile tea, and join us here on a fascinating journey into the mysterious universe of sleep.
