Doctor explains why rubbing the ears and massaging the little finger do not 'boost blood flow to the brain'
Cardiologist Alina Gavrilova told Gazeta.Ru that the body has no 'secret buttons' for boosting the brain's blood supply: supply depends on oxygen levels, hemoglobin, and blood flow, which the brain regulates itself. Popular tips such as rubbing the ears or applying ice to the little finger have no scientific support.
