Cultural exchange is the sharing of ideas, beliefs, and customs between different cultures. It happens when people from different places interact through travel, trade, or communication. This process has taken place throughout history.

Languages, foods, clothing styles, and technologies often spread through these interactions. For instance, foods like noodles and spices moved between regions, and religions such as Buddhism and Islam spread across large areas. Cultural exchange can happen between individuals, groups, or entire countries.

It is studied in history and geography through records, artifacts, and traditions. Cultural exchange helps show how societies are connected across time and place.
