Good news for shift workers! The Wall Street Journal is reporting that recent sleep studies have found that 7 hours is the optimal amount of sleep, not 8 as were recommended in the past. One study showed that cognitive performance increased as people got more sleep, reaching a peak at seven hours before starting to decline. Another found the lowest mortality and morbidity with 7 hours. Researchers are also reporting that too much sleep may be as harmful as too little sleep. The new sleep guidelines are expected to be issued in 2015.
