Today Began Last Night
Genesis 1:5 (NIV) “God called the light “day,” and the darkness he called “night.” And there was evening, and there was morning—the first day.”
This particular order, “evening, then morning—the first day” always had me a bit confused. Maybe God was just trying a creative literary approach, I thought. Well, after researching and writing on the subject of sleep’s architecture and benefits, I now see things God’s way: The day does begin the night before!
Sleep, as created by God, is not merely downtime—the space in between productivity—it’s a vital time of restoration, rejuvenation, and re-creation. It is what literally makes (or breaks) our upcoming day. Not convinced? Here is a small sample of “while you were asleep” processes:
- Replenishment of hormones and brain neurotransmitters
- Growth of new brain cells
- Rebuilding and repairing of nerves, bones, and muscles
- Shoring up of immune system
- Consolidation of memories
So how much sleep should you aim for each night? That would be the same answer you’ve read for years: 7-8 hours, all in a row. A recent study conducted in London, England demonstrated a significant decrease in longevity for those who regularly slept less than seven hours. If you fail to take advantage of 20% (or 1 ½ hours) of your designed sleep requirements, you will have a 20% shortage of the above listed benefits. Now that’s the kind of motivation you and I need to remain faithful to our pillows!
So sleep tight, and sleep right…though the night.
