Why Do You Always Get Sick After Exams

The video explains why people often get sick after stressful events like finals. Stress triggers the fight or flight response, increasing cortisol levels and shifting the immune system from a generalized to a specific pathogen response. This shift delays the immune response, making individuals more susceptible to illness post-stress. After the stress ends, cortisol levels drop, and the immune system relaxes, potentially too much, leaving the body vulnerable to pathogens.

Explain the difference between cellular immunity and humoral immunity as described in the text.
