Few health practices have received as much attention as meditation in recent years. It’s been hailed as a panacea for ills as diverse as addiction, depression, anxiety, attention deficit disorder, an insomnia. Indeed, the scientific research on meditation is largely positive, and there are good reasons to consider practicing it. However, as with any health craze, enthusiasts tend to jump the gun. Some advocates of meditation claim that it can actually replace a large portion of the time you need to sleep. It’s at this point that well-meaning advice can become dangerous.
