How can sneezing spread cold viruses?

Sneezing spreads cold viruses primarily through respiratory droplets that are expelled when a person sneezes. These droplets can contain viral particles and can travel several feet, landing on surfaces or being inhaled by others nearby. Additionally, if someone touches a contaminated surface and then touches their face, they can also become infected. This makes sneezing a highly effective way for cold viruses to spread in crowded or close-contact environments.
