If you experience some symptoms of a cold, you shouldn't worry too much about it. A common cold usually heals on its own in about seven days, and it tends to resolve naturally. However, if you experience a cold accompanied by headaches, fever, coughing, phlegm, or sore throat, this could be more serious and might be due to a viral or bacterial infection. In such cases, under the guidance of a doctor, you can take appropriate anti-inflammatory or antiviral medications. It's also important to stay hydrated to boost metabolism and enhance the body’s immunity. Make sure to keep warm and avoid exposure to cold drafts. During a cold, avoid smoking and alcohol and cooperate actively with medical treatment. Additionally, maintaining a positive mood is crucial as stress can adversely affect recovery from illness.
