The researchers tested the effectiveness of the extracellular vesicles after the person was outside for fifteen minutes at a temperature of 4.4 degrees Celsius, and the result was clear.

Approximately 42% of the extracellular vesicles then disappeared from the nasal cells, leaving room for possible infection.

“How can we exploit this natural phenomenon and re-establish a defense mechanism in the nose and enhance this protection, especially during the colder months?” Then he asked the researchers who are now looking for solutions such as nasal sprays to strengthen the nasal immunity, and reduce the risk of infection Viral diseases And contagious in the winter.
