There is currently no proven effective treatment for cough due to an upper respiratory infection like the common cold. While over-the-counter cough syrups and remedies may provide temporary relief, they do not cure the underlying viral infection. Most cases of cough caused by the common cold resolve on their own within a week or two as the body fights off the virus. Staying hydrated, using a humidifier, and consuming warm fluids like herbal teas or broths can help soothe the throat and alleviate symptoms. In cases where the cough persists or worsens, it is important to consult a healthcare professional to rule out other underlying conditions.
