What are some hobbies or activities that improve cognitive health?

Engaging in specific hobbies and activities can indeed improve cognitive health.

Studies show that activities like playing musical instruments, solving puzzles (e.g., crosswords, Sudoku), learning a new language, and participating in strategic games (e.g., chess) stimulate cognitive functions such as memory, problem-solving, and attention.

Regular physical exercise, particularly aerobic activities like swimming or dancing, has also been linked to better cognitive function. These activities enhance brain plasticity and promote the growth of new brain cells.
