How fast is a sneeze?
A sneeze expels air at speeds up to 160 km/h (100 mph), making it one of the body's most powerful reflexes. A single sneeze can produce up to 40,000 droplets that travel up to 8 metres. Crucially, the 'sneezes at 160 km/h' figure is widely cited but the original research found average speeds closer to 4–5 m/s (16–18 km/h).
