There is some emerging evidence that more benefits may result from spending more time in mindfulness practice, but I would suggest letting your experience be your guide. What feels right to you? Do you notice the impact of your practice on the rest of your life? Would you appreciate more of whatever it is that you notice? That could be the answer to your question. But curiosity should really be your guide in this situation. See if you might look at extending your practice as a kind of experiment or adventure—try adding 5, 10, or 15 minutes—letting go of specific expectations about what that longer practice might yield, and simply show up and be curious. See what you notice, just like you always have. Some people find that when they practice for longer than 15 minutes, they face challenges that never arise in shorter practice sessions. That may or may not be your experience, but you’ll never know unless you try. And as far as science knows, you’re very unlikely to overdose on a little bit of regular meditation practice!
