Donna Griffiths holds the world record for the longest sneezing fit, which lasted 978 days.

Donna Griffiths, a 12-year-old from Pershore, Worcestershire, began her record-breaking sneezing fit on January 13, 1981. During the initial stages of the episode, she was sneezing at an incredible rate of approximately once every few minutes. Medical professionals were baffled by her condition, as standard treatments for allergies and colds failed to provide any relief.By the time her first year of sneezing concluded, experts estimated she had sneezed roughly one million times. The frequency eventually slowed down to once every five minutes as the fit progressed into its second and third years. Her ordeal finally came to an end on September 16, 1983, after a total of 978 days. This remains the longest sneezing fit ever documented by the Guinness World Records.Intractable sneezing, known medically as sternutation, is often linked to psychogenic factors or neurological triggers rather than simple irritants. In Donna's case, the exact physiological cause remained a mystery to the doctors who examined her during the 1980s. Such prolonged fits are extremely rare and can cause significant physical exhaustion and strain on the abdominal muscles. Her case is still cited in medical literature as the primary example of chronic sneezing.
