A third of our life is spent sleeping. How much sleep a person needs changes as one ages. A new mother needs seven hours of sleep per night, but her newborn baby needs 12-18 hours of sleep per night. In general, the older you get, the less sleep you need. This can give us an idea of why sleep is so important during childhood for both growth and brain development. Without proper sleep, we derail our biological defense from heart attacks, strokes, obesity, diabetes, mood disorders and chronic bodily aches.
