Regular kangaroo care improves sleep-wake cycle regulation and physiological stability in premature infants
In a randomized controlled trial of 36 premature infants, regular kangaroo care (KC) for three consecutive days (twice daily, 60 minutes per session) significantly improved Bispectral Index (BIS) values, heart rate, respiratory rate, oxygen saturation, and body temperature compared to control. No significant effects were observed on infant body weight or maternal breast milk cortisol and melatonin levels.

Regular kangaroo care improves sleep-wake cycle regulation and physiological stability in premature infants The current body of evidence comprises 1 study, including 1 randomized controlled trial. EvidenceHub rates the overall confidence at 42/100 (low).
The Claim
Regular kangaroo care improves sleep-wake cycle regulation and physiological stability in premature infants
This conclusion is most relevant to: Premature infants in a neonatal intensive care unit (NICU) in Türkiye.
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Impact of kangaroo care on circadian rhythm, growth, physiological stability in premature infants, and cortisol and melatonin levels in maternal breast milk: A randomized controlled trial. (Midwifery, 2026) —
How It Works
The proposed biological pathway:
- ▸Kangaroo care provides skin-to-skin contact, promoting maternal-infant bonding and thermal regulation.
- ▸This contact may stabilize autonomic nervous system activity, reducing physiological stress.
- ▸Improved autonomic stability leads to more organized sleep-wake cycles and better physiological parameters.
- ▸Result: Enhanced sleep-wake regulation and physiological stability in premature infants.
Who Might Benefit
Evidence fit by population:
- ▸Premature infants in a neonatal intensive care unit (NICU) in Türkiye
Recommended Dose
60 minutes per session, twice daily for 3 days
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Small sample size (36 infants) may limit generalizability.
- ▸Short intervention duration (3 days) may not capture long-term effects.
- ▸Single-blind design may introduce bias in outcome assessment.
- ▸No significant changes in breast milk cortisol/melatonin, suggesting KC may not influence these hormonal pathways within the study period.
Frequently Asked Questions
What is kangaroo care?▼
Kangaroo care is a method of caring for premature infants involving skin-to-skin contact with the parent, typically on the chest, to promote physiological stability and bonding.
How does kangaroo care affect sleep in premature infants?▼
This study found that regular kangaroo care significantly improved sleep-wake cycle regulation, as measured by Bispectral Index (BIS) values, in premature infants.
Does kangaroo care affect maternal breast milk hormones?▼
In this study, no significant changes were observed in cortisol or melatonin levels in maternal breast milk after three days of kangaroo care.
What physiological parameters are improved by kangaroo care?▼
The study reported significant improvements in heart rate, respiratory rate, oxygen saturation, and body temperature in premature infants receiving kangaroo care.
