Colds, or viral infections of the upper respiratory tract, exhibit symptoms we all know well- stuffy or runny nose, cough, sneezing, sore throat, general aching, and a low fever. While most adults have 2-3 colds a year, children often report more! Studies suggest that early daycare attendance results in more colds during the preschool years for children, increased protection against cold during elementary school years, and is neutral once children hit about 13 years old. Though the common cold is not generally harmful, it can be problematic for families if it results in school or work absenteeism, a problem scientists seek to remedy with progress on a vaccine for the common cold.

While we await a vaccine or cure, prevention against the common cold includes good sleep habits, stress mitigation, and handwashing. Zinc has also demonstrated to be likely beneficial, while the studies on vitamin C and cold prevention are more mixed, with some suggesting helpfulness and others reporting little to no effect.
