1. Understanding the Common Cold and Its Symptoms
The common cold, a prevalent upper respiratory infection, is something most adults experience multiple times a year. According to the National Institutes of Health, adults typically get 2-3 colds annually. Caused primarily by viruses like rhinovirus, cold symptoms usually manifest a few days after infection and can linger for up to two weeks.
What are the main symptoms of a cold?

In rare instances, more severe symptoms like fever, dehydration, or breathing difficulties may occur, necessitating medical attention.

Diet plays a vital role in managing cold symptoms and supporting your body’s recovery. Choosing the right foods can alleviate discomfort, strengthen your immune system, and potentially shorten the duration of your illness.
