Extract: A technique called "electrical grounding" may moderate preterm infants’ electromagnetic exposure in the neonatal intensive care unit (NICU)
- and improve their health outcomes, according to Penn State College of Medicine researchers.
Equipment in the NICU produces low-frequency electromagnetic fields that can have subtle yet measurable effects on the autonomic nervous system, the system that regulates involuntary body functions. Preterm infants may be especially vulnerable to these effects.
Previous research in adults has shown that exposure to electromagnetic fields can affect the vagus nerve, a key component of the autonomic nervous system which regulates the body’s internal organs during rest. Previous research also has shown that electrical grounding, which reduces the electrical charge to the body, can improve the functioning of the autonomic nervous system and the vagus nerve, producing improved vagal tone.
