Women’s Health set out to answer the age-old question: What actually is a sneeze, and what causes it?

Dr. Jackman says that's because “you don’t have enough stimulation to cause a sneeze.” You can make yourself sneeze, however by “increas[ing] the stimulus,” she adds. This can be done by sniffing pollen or by humming, which "vibrates the nasal hair and triggers the same neural pathway," says Dr. Jackman.
