All of us have had to plow through at least one difficult day of school or work after a less-than-optimal night of sleep. But what happens when a rough night becomes the norm? The Centers for Disease Control collects data about the sleep habits of Americans and reports that one in three of us are getting fewer than the recommended seven hours of sleep per night. Whether you can’t fall asleep, can’t stay asleep, or both, insomnia is not only miserable but bad for your health. I’m one of those insomniacs who wakes up more nights than not after about four hours of shut-eye, and who’s unable to drift off again for at least an hour or two. If you’re like me and have spent many wakeful hours wishing you could just relax and sleep, it’s time to find some help. I’ve been researching why insomnia occurs, as well as testing iPhone gear and apps meant to deliver a good night’s sleep. Here, I’ll share the tips, apps, and gear that have been most effective so far in my quest to cure my insomnia.
