Why are hospitals so cold?

This joke is a play on words that involves a dark sense of humor. In the joke, “hospitals” are mentioned, which are known for maintaining a cooler temperature for various reasons, including inhibiting the growth of bacteria and providing a more comfortable environment for staff in layers of personal protective equipment. However, the punchline, “to keep the vegetables fresh,” uses a colloquial and insensitive term “vegetables” to refer to patients in a comatose or vegetative state who are unable to move or communicate. The humor is derived from the unexpected twist of equating the term with actual vegetables that need refrigeration to stay fresh, combining the clinical aspect of a hospital with the mundane task of preserving food.
Also, a certain wing of patients at long-term acute care facilities are on life support, and the majority of these patients are typically not conscious and awake. Known as the vegetable garden by nurses. Because they don’t care about the patient, employ them to instruct novices when they have to perform blood draws and other procedures.
