Why do biscuits taste stale in cooler weather?

Biscuits may taste stale in cooler weather due to changes in humidity and temperature, which can affect their texture and moisture content. Colder air is often drier, leading to moisture loss in the biscuits, resulting in a harder and less flavorful texture. Additionally, the perception of taste can be influenced by the temperature at which food is consumed; colder biscuits may not release their flavors as effectively as when they are warm.
