Shivering is the physiological response to environmental temperature changes that is missing or undeveloped in infants less than 6 months of age. Infants have a limited ability to regulate their body temperature because they have a relatively large surface area compared to their body weight, and their thermoregulatory system is not fully developed. Infants rely on non-shivering thermogenesis (brown fat metabolism) to generate heat in response to cold environments. Fever, flushing, and shock are not temperature regulation responses, but rather general responses to various stimuli or conditions.
