What are the advantages of swaddling?

This was discussed by Bregje E. van Sleuwen, Adèle C. Engelberts, Magda M. Boere-Boonekamp, Wietse Kuis, Tom W.J. Schulpen and Monique P. L'Hoir. Swaddling: A Systematic Review. Pediatrics October 2007, 120 (4) e1097-e1106; DOI: https://doi.org/10.1542/peds.2006-2083 “In general, swaddled infants arouse less and sleep longer [EM: Not necessarily a good thing]. Preterm infants have shown improved neuromuscular development, less physiologic distress, better motor organization, and more self-regulatory ability when they are swaddled. Excessively crying infants cried less when swaddled, and swaddling can soothe pain in infants. It is supportive in cases of neonatal abstinence syndrome and infants with neonatal cerebral lesions [EM: This justifies its use in NICU].”
