Is it true that a sneeze can release up to 100,000 germs?
assistant
Yes, a sneeze is an involuntary reflex action which releases up to 100,000 germs. A sneeze can be caused by the contraction of the muscles in the nasal cavity, and when this happens, air is forced through the nose and out of the mouth. This causes a burst of air containing millions of airborne particles such as pollen, dust, bacteria, and viruses, all of which are released into the atmosphere.
