The human body is not just a dynamic sophisticated biochemical and genetic system; there are strong energetic, emotional and psychological aspects that interact decisively with the physical counterparts of the body and can make a very measurable difference in our physiological functions.

A valid proof of this comes from the neonatal Kangaroo care method (K method), which requires skin to skin contact between the mother and the newborn baby. While this simple intervention provides superior support for preterm, low-weight babies, in comparison to conventional practices, such as the use of incubator, it is rarely included in official hospital policies or recommended to mothers by mainstream experts.

Pediatricians have expressed fears that keeping a preterm baby outside of an incubator during the Kangaroo interaction, may expose the infant to cold with subsequent loss of body heat and lower body temperatures, which can be critical to the survival and wellbeing of weak babies. Research however shows that the exact opposite is happening during the K care method. A study involving low-weight preterm babies (less than 1.5 Kg) and their mothers, published in the Journal of Pediatrics, found that the body temperature of the newborn actually rises when the infant is skin to skin in touch with the mother's chest.
