In neonates (newborn infants), brown fat makes up about 5% of the body mass and is located on the back, along the upper half of the spine and toward the shoulders. It is of great importance to avoid hypothermia, as lethal cold is a major death risk for premature neonates. Numerous factors make infants more susceptible to cold than adults:

Newborn babies, infants, and young children experience a greater (net) heat loss than adults because of greater surface-area-to-volume ratio. As they cannot shiver to maintain body heat, [ citation needed ] they rely on non-shivering thermogenesis .
Thermogenesis is the process of heat production in organisms. It occurs in all warm-blooded animals, and also in a few species of thermogenic plants such as the Eastern skunk cabbage , the Voodoo lily ( Sauromatum venosum ), and the giant water lilies of the genus Victoria .
Physiology: Newborns lack the ability of thermogenesis due to underdeveloped shivering mechanism. Body heat is lost through conduction, convection, and radiant heat. [ 1 ] Thermoregulation is achieved through several methods: the metabolism of brown fat and Kangaroo care, also known as skin to skin.
In his 2007 paper, Nedergaard pointed out that brown adipose tissue is present and active in adult humans. [19] He has also contributed to the establishment of basic concepts in brown adipose tissue research, [ 17 ] including the developmental differences between brown and white adipocyte precursors, where the brown adipocytes precursors ...
Transient tachypnea of the newborn is a respiratory problem that can be seen in the newborn shortly after delivery. It is caused by retained fetal lung fluid due to impaired clearance mechanisms. [1] It is the most common cause of respiratory distress in term neonates.
Sarcolipin is an important mediator of muscle based non shivering thermogenesis (NST). It causes the sarcoplasmic reticulum Ca 2+-ATPases to stop pumping Ca 2+ ions but continue futilely hydrolysing ATP, thus releasing the energy as heat. [6] [7] Sarcolipin mediated heat production is very important for many organisms to maintain a warm body.
