How does negative feedback work in cold conditions?

Negative feedback in cold conditions helps maintain homeostasis by triggering physiological responses to restore body temperature. For example, when the body senses a drop in temperature, it activates mechanisms such as shivering to generate heat, and constriction of blood vessels to reduce heat loss. Additionally, the hypothalamus signals the release of hormones that increase metabolic rate, helping to generate more body heat. This process continues until the body temperature returns to its set point.
