It happened at Heather Brown’s home this past weekend. So, she wondered: Why do we sleep? Good Question.
“We don’t know is the short answer to that question,” says Dr. Andrew Stiehm, a sleep specialist at the Allina Health United Lung and Sleep Clinic. “There are lots of thoughts behind why we might need to and I think the answer is broad.”
Dr. Stiehm says, despite beliefs to the contrary, sleep is a productive time for all complex animals. Our brains are very busy when we sleep, but in a different way than when we are awake.
