Why is it important to leave space for air circulation in a refrigerator?

Leaving space for air circulation in a refrigerator is vital for promoting even cooling throughout the appliance. When air can flow freely around the food items, it ensures that every area of the refrigerator maintains a consistent temperature. This consistent cooling is important to keep food fresh and safe for consumption, as uneven temperatures can lead to spoilage or the growth of harmful bacteria.

If food items are packed too closely together, or if there isn't enough space around them, the cold air cannot circulate properly. This can result in some items not being cooled adequately while others may get too cold, leading to uneven temperatures. Therefore, creating space for air circulation directly contributes to food safety and quality by supporting optimal cooling processes.
