Neonates rely on several mechanisms for thermoregulation: 1. Non-shivering Thermogenesis: Brown adipose tissue generates heat without muscle contractions. 2. Peripheral Vasoconstriction: Reduces blood flow to the skin to minimize heat loss. 3. Behavioral Responses: Crying and increased activity can generate heat.
However, these mechanisms are often insufficient in neonates, particularly in preterm infants, making external interventions necessary.
