Who doesn't love a good night's sleep? The Division of Sleep Medicine at Harvard and WGBH have collaborated to produce the Healthy Sleep website to help "illuminate the relevance of sleep, explain the underlying science of sleep, and, most importantly, provide practical information for getting the sleep you need." Visitors interested in getting the sleep they need will find the many videos and interactive features here well worth their time. Under the "Why Sleep Matters" link, visitors will find an interactive timeline entitled "Historical and Cultural Perspectives of Sleep". The "Consequences of Insufficient Sleep" gives visitors the choice of several short videos to watch, including those that address the consequences of driving while drowsy, the link between disease risk and poor sleep, and the public safety and performance issues that arise due to insufficient sleep. The "Getting the Sleep You Need" link has many tips for visitors on how to approach poor sleep habits, including when to seek treatment.
