You are a miracle - Sneezing Storm

Sneezing is a protective reflex action in humans. When the nasal mucosa is stimulated, it triggers the trigeminal nerve to send signals to the brain, causing the respiratory muscles to rapidly contract and produce strong airflow. The speed of this airflow can reach 160 kilometers per hour, equivalent to the wind speed of a 14 level typhoon (157-187 kilometers per hour). Sneezing can effectively remove foreign objects and irritants from the nasal cavity, protecting respiratory health.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Sneezing is a reflex behavior in which the nerve endings on the nasal mucosa transmit external stimuli to the brain. The brain gives instructions to command the contraction of muscles in the face, chest, and abdominal cavity, resulting in a series of movements. For example, when stimulated by cold air, the nasal mucosa will swell and enter a "preheating" state. Afterwards, the "signal" will be transmitted through the upper respiratory tract, brain, and other processes, and a sneeze will be born. When sneezing, the airflow in the nasal cavity will be released outward at a speed of 177 kilometers per hour, which can reach a speed of over 40 meters per second, equivalent to a force 12 wind defined as a speed greater than 32.7 meters per second.
