Do lemons shrink in size if left out?

Yes, lemons can shrink in size if left out at room temperature for an extended period. This occurs due to moisture loss through evaporation, which causes the fruit to dehydrate and lose its plumpness. Additionally, exposure to air can lead to the breakdown of their structure, further contributing to their shriveling. To maintain freshness, it's best to store lemons in a cool, dry place or refrigerate them.
