It’s tempting to take a pill or just sip sleep-inducing tea, but these quick fixes don’t address the root of what’s keeping you awake at night. As this video from The School of Life explains, your insomnia might be a result of something simple you’re forgetting to do during the day—that is, think. Just running through your to-do list won’t help, though. It’s those bigger, more philosophical questions (Am I happy? Am I in the right job? Am I with the right person?) that need attention during daylight hours—or else they’ll pop up late at night. So set aside some time to reflect on your career, relationships, regrets, or purpose and prepare to catch some more zzzs.
