Everyone knows that meditation can reduce stress. But researchers at Massachusetts General Hospital say it directly affects the function and structure of the brain. It increases attention span, sharpens focus, and improves memory.

With the aid of advanced brain scanning technology, one study showed that daily meditation thickens the parts of the brain's cerebral cortex responsible for decision-making, attention, and memory.

With practice, you can develop a state called mindfulness, which is being aware of what's going on as it arises without jumping to conclusions, judgments, hopes, fears, or plans.

Meditation also improves productivity and reduces absenteeism at work, probably because it helps prevent stress-related illness. 

Meditation seems to aid with emotional regulation, which helps people get along better. It acts on emotional intelligence, which neuroscientists say is more important for life success than cognitive intelligence.
