In the morning news business, the topic of sleep comes up quite often. The Wall Street Journal says several sleep studies have concluded that seven hours is the optimal amount of sleep, not eight as was long believed. At seven hours, researchers found people achieved their best cognitive performance. Not getting enough sleep impairs memory and performance the next day and getting too much sleep can lead to diabetes, obesity and cardiovascular disease.
