The Sudoku is therefore perfectly suited to keep synapses healthy!
Challenge your mind. Tackle puzzles, games and demanding intellectual tasks. Make an effort to learn new information through classes or reading.
Reduce stress. Make time for leisure activities. Learn relaxation techniques such as meditation. Cut down on unnecessary responsibilities and avoid over-scheduling.
Exercise. A brisk walk or other cardiovascular workout oxygenates the brain and promotes brain growth factors.
Stay healthy. Eat a nutritious diet, get adequate sleep, avoid smoking, and if you use alcohol, drink in moderation.
