What fruits to eat when having a cold and fever?

In cases of cold and fever, it is advisable to eat more fruits rich in vitamin C, such as oranges, grapefruits, kiwis, strawberries, and cherries. These fruits contain a high amount of vitamin C, which can enhance the body's immune system, promote inflammation repair, and help the disease recover more quickly. It is also recommended to drink plenty of water during a fever to replenish fluids timely and avoid dehydration that can cause electrolyte imbalance. Additionally, if the body temperature exceeds 38.5°C, fever-reducing medications should be taken to lower the temperature. Moreover, it is advisable to rest well, avoid overexertion, keep warm, avoid exposure to cold winds, and eat a light diet devoid of spicy, greasy, or raw and irritating foods. (Please consult a professional physician before using any medication, and do not medicate blindly.)

What should you avoid eating when you have a cold and fever?

There are many foods that should not be consumed during a fever caused by a cold, such as spicy foods including chili peppers, black pepper, mustard, onions, ginger, and garlic. Avoid these items, as well as fried foods, foods high in fat, overly sweet foods, and overly sour foods, for example, fried foods, pork belly, pig head meat, or some candies, creams, cheeses, and pastries. Furthermore, attention should also be given to avoiding carbonated drinks, alcoholic beverages, strong tea, and coffee. The diet should be light with the option to consume things like millet porridge, vegetable porridge, or some freshly squeezed juices to provide vitamins and enhance body resistance, helping to expedite recovery from cold and fever symptoms. During a fever, it is important to monitor body temperature. If it exceeds 38.5°C, fever-reducing medication should be taken; otherwise, physical cooling methods can be sufficient.

What are the symptoms of a cold in children?

Pediatric colds, also known as acute upper respiratory infections, exhibit symptoms that can be categorized into local and systemic symptoms. Local symptoms include nasal congestion, sneezing, runny nose, mild coughing, discomfort in the throat, and sore throat. Systemic symptoms primarily consist of overall weakness, fever, reduced appetite, nausea, vomiting, diarrhea, abdominal pain, and generalized aches. In infants and toddlers, local symptoms are generally not as pronounced, while systemic symptoms tend to be more severe. For some children aged six months to three years, colds accompanied by fever can also lead to febrile convulsions. In older children, local symptoms are usually more prominent, while systemic symptoms are milder. Regarding this type of acute upper respiratory infection, there are two common specific types in children: herpangina and pharyngoconjunctival fever.

What should I do if I have a heavy nasal voice due to a cold?

Cold with nasal voice, in most cases, does not require special treatment. A cold can cause symptoms such as runny nose, sneezing, nasal congestion, sore throat, and coughing. These symptoms can lead to a nasal voice in patients, and this condition usually does not require special treatment. If the symptoms of runny nose, sneezing, and nasal congestion are particularly severe and affect the patient's daily life, some compound cold medicines can be used to alleviate the symptoms, such as compound cold medicines like Ammaminamide tablets. Additionally, for a heavy nasal voice due to a cold, it is also necessary to assess the patient's condition. If the patient has a lot of purulent nasal discharge and is accompanied by headaches, it is important to be alert to the possibility of sinusitis, which also needs to be treated. (Please use medication under the guidance of a doctor.)

What should I do if I have a cold with heart failure?

Infections are a primary cause of worsening heart failure. Patients with heart failure who catch a cold should treat the cold, and if the cold exacerbates the heart failure, they should also treat the heart failure simultaneously. Patients with heart failure should always try to avoid infections by regularly ventilating their living spaces, avoiding crowded places prone to cross-infections, and dressing appropriately for the weather. Additionally, patients should engage in appropriate exercise to boost their immune system, but they must balance activity and rest.
