Womb is a “Secure receptacle” indicates an important feature where embryo completes its 9 months of development. The mother’s womb provides insulation against external agents, light and sound, variations in temperature and protects the baby against shock and pressure.1 In the womb, the fetus is protected from internal and external pressure by a wealth of natural shields and the fetus is safe in the womb because it is well insulated and designed as the perfect baby carrier.2 during intrauterine life, the fetal temperature is 0.50c higher than the maternal temperature due to methods reaction that generates heat. After the birth, infant is exposed to air and environment which have lower temperature.3 Thermoregulation in adult is achieved by muscular activity and metabolic activity. During fetal life, above mechanism in mother are responsible for maintaining the fetal body temperature.4Newborn infants usually are considered to be tiny and powerless, completely dependent on others for life.5 Newborn infants are unique in their physiology and health problems that they experience.3They are naked, wet and have a large surface area to mass ratio, with variable amounts of insulation, limited metabolic reserves, and a decreased ability to shiver.6 Hypothermia is an essential aspect of neonatal care especially in the immediate neonatal period. So great care is necessary by clothing the baby properly and to maintain the surrounding temperature and humidity, which suits the individual infant.7 Neonatal hypothermia defined by the World Health Organization(WHO) as auxiliary temperature less than 36.50c, is a major contribution to neonatal illness and deaths both in the developed and developing parts of the world out of 150 live birth aged 0 to 28 days 62%(93) had hypothermia. With an incidence of in which mild hypothermia accounted for 47.3% and moderate is 52.7%.8 Newborn babies have poor heat regulating mechanisms because of larger surface area of babies compared to their weight making them prone to hypothermia and its ill effects. Heat loss in a newborn occurs through 4 routes- radiation, convection, conduction and evaporation
