💤 Breastfeeding Reduces Risk of SIDS by 36%
📊 The Evidence:
A major meta-analysis published in Pediatrics (2017) reviewed data from over 9,000 infant deaths and found that any breastfeeding, regardless of exclusivity, was associated with a 36% reduction in the risk of Sudden Infant Death Syndrome (SIDS).
Exclusive breastfeeding for at least 2 months reduced SIDS risk by up to 50% — and the protective effect increased with duration.
🤔 Why does breastfeeding protect against SIDS?
There’s no single cause of SIDS, but breastfeeding may help by:
🛡️ Enhancing immune protection
Breastmilk contains antibodies and immune factors that protect against infections — especially respiratory and gastrointestinal illnesses, which are linked to increased SIDS risk.
🧠 Supporting neurological and cardiorespiratory development
Breastfed babies tend to have more stable heart rates, better arousal responses from sleep, and improved brainstem function — all crucial for survival during sleep disruptions.
🌡️ Reducing inflammation
Human milk reduces inflammatory markers and may promote better autonomic regulation, which helps prevent sudden cardiorespiratory failure during sleep.
👃 Decreased exposure to harmful pathogens
Breastfeeding reduces the risk of infections and bacterial colonization, particularly in the upper respiratory and gastrointestinal tracts.
🗣️ Bottom Line:
Breastfeeding — even partial — is a powerful, evidence-based way to reduce the risk of SIDS. Promoting and supporting breastfeeding is one of the most impactful public health tools we have for infant survival and safety.
