It is not recommended to drink tea when having a cold; it is advised that patients drink more plain water instead. Patients also need to maintain a light diet and eat some fruits, and it’s recommended to avoid both tea and carbonated beverages, as well as alcohol. For conditions like the common cold, it is important to avoid staying up late and overexerting oneself. The common cold is usually self-limiting, meaning it will typically resolve on its own as the patient's immune system fights off the illness. However, if the symptoms of a cold are severe, it may be necessary to take medication for symptomatic treatment. It is also important to note that while the common cold is usually self-limiting and does not often lead to serious consequences, complications can sometimes arise. For example, it could lead to acute sinusitis or bacterial pneumonia. If a cold sufferer's symptoms persist or worsen, it is important to seek medical attention promptly for proper treatment.
