A new study shows 10X improvements in cognitive tests (including ability to focus) from doing brief meditation. That's not too surprising by itself, as the benefits of meditation have been shown in neuroimaging and behavioral studies for years. What is surprising, though, is that it doesn't take much to see results.
As it turns out, you don't have to train like a monk for years to get these benefits of enhanced cognitive skills. Researchers found profound improvements after just four days of 20 minutes training per day, doing simple "mindfulness" meditation.
There's a write up over at sciencedaily.
If you haven't given this sort of thing a try, I highly recommend it.
