Skeptics frequently have questioned why an all-powerful, all-wise God would have designed human bodies to require an average of eight hours a day of sleep. It seems inefficient because there’s too much “down time.” A team of neuroscientists recently discovered that while the muscles in the human body typically do not require eight hours a day in order to function optimally, the brain does. They found that sleep is particularly beneficial for inspiring insight into challenging mental problems. Sleep inspires brilliant thinking. Therefore, what appears to be an inefficiency in human bodies actually reflects the efficiency of a wise Designer.
