Just as sure as night and day, sleep is a part of life – not just a part, but an integral part. It’s the way we are made. Machines can be made to run day-and-night weeks at a time, but not the human body. A few decades ago, a lot was written about how cetaceans (dolphins and whales) never slept, because they would drown if they did. Now we know that they do sleep, but with only half the brain at a time. The surprise to many of us is that some sleep about one third of each day.
Makers of mattresses, pillows, adjustable beds, accessories, air purifiers, and other bedroom furnishings often include in their pitches that we spend one-third of our lives in bed. That may be true if we are in bed an average of eight hours a day, but the truth is that many of us – if not most – spend less time than that sleeping or trying to sleep.
Before we start measuring sleep with a stopwatch, we should consider that how much sleep we need is not a set time. How much depends on our age and individual makeup. So recommended sleep times are in ranges of hours. What is important is completing the cycles in our sleep patterns.
