The Proper Time for Work
A child’s brain, and its body as well, are in the prime of their vigor during the morning hours. From nine till noon, therefore, should be the period of the hardest mental or physical work he undergoes. Evening preparation of lessons is harmful, not only because it tends to bring into a state of high activity the brain, which shortly should be quiet and ready to sink into slumber, but also because it throws hard work on an already fatigued organ. Much of the nervousness, debility, and insomnia so common among school children can be traced to evening preparation.
