Impact of Stress on The Susceptibility to The Common Cold

Stress negatively affects the immune system (more stress → more susceptibility to colds)
The lack of antibodies in a person’s blood made them more susceptible to colds
- However, this data was not statistically significant
Healthy subjects were given one of five types of respiratory viruses in the form of nasal drops
- These included: RV Type 2, RV Type 9, RV Type 14, respiratory syncytial virus, or coronavirus type 229E
  - Respiratory viruses target the lungs, which leads to airway blockage (i.e. alveoli are unable to conduct gas exchange), wheezing, and other symptoms that affect breathing
- The control group was given saline nasal drops
- Those with coronavirus type 229E showed higher stress, thus more infections
