Question

A five-year-old child experienced blue lips and red, swollen eyes while skating. What could be the cause?

Answer

The low water temperature during skating or the child swallowing water could be contributing factors. The breathing rhythm during skating is different from that in everyday life, and the need to kick the water can accumulate a certain amount of oxygen debt within the body. Low water temperature is the main reason for the blue lips, as the cold water causes the constriction of superficial blood vessels on the body, slowing down the superficial blood circulation, and reducing the oxygen content in the blood. This is a suggested explanation for this issue, and I hope it is helpful to you. Wishing you good health!
