Research on puzzles show that they cause continuous activity throughout the brain (right and left sides) and this helps to exercise the brain cells and thereby activate them and increase their efficiency and capacity. This helps to prevent ALzheimers, memory loss and dementia. When doing puzzles, studies have shown that dopamine is released, which is chiefly responsible for leaning and memory. It helps to make one alert, increases concentration and creativity, and helps practice visualization. Physically, it helps to lower blood pressure, and heart rate. It assists with a meditation state, and helps to induce a certain calmness.
