Clear nasal discharge is a symptom of a cold caused by a viral infection due to catching cold. The viral infection can lead to the swelling of the nasal mucosa, increased secretions, and mucosal edema, hence the occurrence of clear nasal discharge, which is a typical early sign of a cold. During this period, it is necessary to maintain indoor air temperature and humidity, avoid eating highly irritating foods, and avoid exposure to smoke, dust, and other irritating chemical gases. Drink plenty of water, and consider taking medications known to affect glandular secretion, as well as vitamin supplements to promote the repair of tissue mucosa.

Do you have a cold and cough?

A cold, also known as an upper respiratory tract infection, is commonly caused by a decrease in immune function, leading to symptoms such as nasal congestion, runny nose, sneezing, sore throat, and fever due to viral invasion of the respiratory tract. Additionally, it is quite common for patients to experience varying degrees of cough during a cold. Due to the different pathogens that trigger colds, there is a significant variation in the clinical symptoms exhibited by patients. Naturally, the severity of symptoms also varies depending on the individual's immune strength. Thus, in treating colds, some patients might experience a dry cough initially and later develop a productive cough. These are both common occurrences, and effective control can be achieved with appropriate symptomatic treatment.

How to get over a cold quickly?

The common cold is one of the most frequent infectious diseases seen in clinical practice and is also a self-limiting illness. It is often caused by factors such as exposure to cold, staying up late, stress, and lack of sleep, which lead to decreased immunity. Consequently, viruses or the influenza virus may take advantage and infect the body, causing symptoms of the common cold. To treat a cold, one should first drink plenty of warm water and measure their temperature twice daily. The main principle of treatment is symptomatic treatment and antiviral management. One may choose to take Ribavirin or Qingkailing for antiviral treatment. If symptoms like fever and runny nose are present, one can opt for antipyretic analgesics and drugs that reduce glandular secretions. Concurrently, include more vitamin C-rich foods in the diet. (Medications should be used under the guidance of a doctor.)

Can I eat watermelon if I have a cold and cough?

When suffering from a cold and cough, it is appropriate to eat some watermelon as it contains a lot of water which can help replenish the fluids the body needs. It also has a soothing effect on the throat. However, be careful not to eat too much because watermelon has a high sugar content. Excessive sugar intake can exacerbate coughing by increasing phlegm. Additionally, watermelon has cooling properties, so consuming too much can lead to gastrointestinal discomfort. Patients with weak spleen and stomach, already having frail gastrointestinal systems, may experience discomfort from consuming too much watermelon. It is recommended to eat moderate amounts and maintain a light diet, drink plenty of water, and consume more fruits like apples, pears, or grapefruits which are more suitable. It is crucial to actively cooperate with medical treatment during a cold and cough to alleviate symptoms.

What is wind-heat cold?

Wind-heat cold is a term used in traditional Chinese medicine, referring to a type of cold caused by the invasion of heat into the body. Clinically, it mainly presents with symptoms such as coughing, coughing up purulent sputum, thick and abundant sputum that is difficult to expel, as well as high fever with chills. The body temperature can reach above 39°C within a few hours, and there may also be headaches, dizziness, sore limbs, fatigue, and sore, swollen throat. Therefore, patients with wind-heat cold should drink plenty of water and take some heat-clearing and detoxifying Chinese patent medicines orally. For patients with a body temperature higher than 38.5°C, antipyretic medication such as ibuprofen should be taken orally to reduce the temperature back to normal. In daily life, it is important to focus on a light diet and avoid spicy and irritating foods.

Symptoms of cold and fever in children

Child colds indicate an upper respiratory infection, mostly caused by viral infections, with some triggering bacterial infections. It is very common for children with colds to have fevers. In such cases, it is important to ensure the child is well-hydrated. If the temperature exceeds 38.5°C, fever-reducing medication such as acetaminophen or ibuprofen suspension should be administered. Additionally, cold medications can be taken to alleviate symptoms. When the temperature is below 38.5°C, drinking plenty of fluids is usually sufficient. In essence, the main treatment for a cold is symptomatic relief. Symptoms like fever, runny nose, sneezing, and coughing are all common with colds. (Please take medication under the guidance of a professional physician, and do not self-medicate.)
