Meditation is a dose-dependent drug. Most people will reap most of the health benefits that meditation has to offer by sitting for 20 minutes a couple times a day. You can go much deeper, of course, but that's a philosophical / spiritual quest to gain a deeper understanding of yourself and the world around you - it's not a health pursuit. A multi-day meditation retreat is in many ways like running an ultramarathon: it's not really a healthy undertaking, per se, but you might learn something about yourself by doing it, and the way to do it responsibly is by working your way up to it over months and years of practice.
