<unk>  may elicit the Valsalva reflex. This reflex negatively impacts sucking pressures and results in poor feeding. The cortisol levels will rise along with blood pressure. Increased blood pressure will have an effect on cerebral blood flow, cerebral blood flow velocity and intracranial pressure. Increased pressures and velocity can lead to intracranial hemorrhage. Prolonged exhalation may also cause some adverse effects. Obstructed venous return and quick inspiratory gasp can occur. Foramen ovale shunting can occur. Adults can often determine whether an infant's cries signify anger or pain. Most parents also have a better ability to distinguish their own infant's cries than those of a different child. Babies mimic their parents' pitch contour. French infants wail on a rising note while German infants favor a falling melody. Overstimulation may be a contributing factor to<unk>  and that periods of active<unk>  might serve the purpose of discharging overstimulation and helping the baby’s nervous system regain homeostasis.
