Before the thermometer was invented, people relied on various methods to gauge temperature, such as observing natural indicators like weather patterns, the behavior of animals, and the state of water (e.g., freezing or boiling). They also used simple tools like a stick or metal to feel heat and cold. Additionally, some cultures utilized clinical signs in humans, such as skin color and warmth, to assess body temperature.
