Understanding Colds and Our Body's Response

The video explains how colds are caused by viruses entering the body through the mouth, nose, and eyes. Once inside, these viruses replicate and cause symptoms like runny noses and fevers. These symptoms are actually the body's defense mechanisms working to expel the virus and prevent it from replicating further. Although these symptoms can be uncomfortable, they indicate that the body is actively fighting the infection.
