What is the ring of fire during labor?

The ring of fire during labor is the intense burning and stinging sensation felt in the vaginal and perineal area during crowning, when the baby's head stretches the vaginal opening to its maximum diameter. It is called ring of fire because the stretching of skin, nerves, and tissues creates a hot, burning, circular sensation around the vaginal outlet, as if a ring is on fire. This occurs in the final moments of the second stage of labor, just before the baby's head is born. The baby's head is pressing hard against the perineum, causing tissues to thin and nerves to be compressed, which triggers the burning feeling. The ring of fire lasts from a few seconds to a few minutes and is often described as the most intense and sharp part of vaginal birth. Healthcare providers often ask mothers to pant or do small pushes during this time to allow slow stretching and reduce tearing. Once the head emerges, the burning subsides quickly. Not everyone feels it the same way, those with epidurals may feel pressure rather than burning, but for unmedicated births, the ring of fire is a well-known landmark that birth is imminent.
