A protective reflex that stops breathing when food “goes down the wrong way” may be involved in cot death, scientists have claimed.
Scientists believe poor co-ordination between two parts of the brain that work together to control breathing and swallowing might play a key role in Sudden Infant Death Syndrome (Sids).
The reflex brings the vocal chords together to trigger coughing and swallowing.
The research is published today in the Journal of Physiology.
