Meditation leads to whole brain functioning and synchronization by slowing brain waves from Beta to Alpha to Theta to Delta. This process increases balance between brain hemispheres and allows one to tap into "whole-brain thinking". Benefits include enhanced learning, clarity, memory, self-awareness and problem solving. Deep meditation also increases anti-stress hormones and decreases hormones linked to aging. It can increase human growth hormone levels, leading to benefits such as improved health, memory, energy and skin elasticity.
