After catching a cold and taking cold medicine, it is best not to eat crabs.

After a cold, due to the influence of the virus itself, gastrointestinal function may be impaired; thus, eating crabs at this time is not conducive to digestion.

Furthermore, if you take cold medicine after a cold, these medications may also have adverse reactions with crabs. Since crabs are considered to have a cooling effect, they might react with certain Chinese medicines. Therefore, it is advised not to consume crabs and other seafood products after taking medicine for a cold. It is better to opt for simple home-cooked meals or easily digestible foods, which can aid in digestion and not interfere with the normal absorption of the medication.

Physical cooling methods for colds

Fever symptoms caused by a cold can be treated with physical cooling methods. There are many commonly used methods in clinical practice. For adults, one can wipe the palms, soles, neck, and chest—areas where major blood vessels run—with warm water or alcohol. You can also use a cool towel or ice packs to compress the forehead. Drinking herbal concoctions like scallion water or ginger sugar water can also help reduce fever physically. Additionally, soaking feet in Sichuan peppercorn water can be effective. Regardless of the method used, it's important to drink plenty of water and recheck the temperature after two hours.

Do you need to take medicine for a cold with nasal congestion?

Nasal congestion due to a cold is very common in clinical practice. The need for medication depends on the type of cold and the patient's own immune function. If the patient has a cold caused by a viral infection and the symptoms are not severe, or if the patient generally likes to exercise and is young, a mild cold may not require medication and can heal on its own within about a week. For children or elderly individuals with weaker resistance, when an upper respiratory infection occurs, it is advisable to administer some medication for symptomatic treatment to prevent the condition from worsening and to avoid unnecessary complications.

How to recover quickly from a cold?

If you have symptoms of a cold, make sure to observe what symptoms are present, such as fever, cough, sputum production, limb soreness, and fatigue. If the symptoms are mild, it is likely just a common cold, which should heal in about seven days. Besides avoiding interventions, it is also important to rest more, drink plenty of water, and promote excretion. At the same time, appropriate outdoor activities and physical exercise can enhance physical fitness and help the disease recover more quickly. Additionally, if the symptoms are severe, besides treating the cause, it is also necessary to take some symptomatic medications to alleviate the symptoms. Also, complementing this with daily life routines and some dietary adjustments can help the disease recover more quickly.

How to treat a baby's cold in the early stages?

What are the symptoms at the onset of a cold? Generally, at the initial stage of a cold, we definitely experience symptoms such as a runny nose, nasal congestion, low-grade fever, and slight coughing. If it's just a runny nose and nasal congestion, in this case, we can take some antiviral medications, some proprietary Chinese medicines, and also provide some acetaminophen chlorpheniramine granules to relieve these symptoms of runny nose and nasal congestion. If there is a cough, appropriate cough suppressant medication can be taken orally. At the same time, pay attention to body temperature; if there is a fever, fever reduction measures should be taken. If it is a low-grade fever, physical cooling should be the main approach. If the body temperature exceeds 38.5 degrees Celsius, oral ibuprofen or acetaminophen can be administered. Also, pay attention to the child's mental response and other conditions.

Which department should I go to if I have a cold during pregnancy?

When pregnant and catching a cold, one should visit the gynecology department or the respiratory department for treatment. During a cold, it is advisable to drink plenty of water and rest more. Medication during pregnancy needs to be cautious to avoid arbitrary use, especially of hormones and antiviral drugs. Medication should be decided under the guidance of a doctor, based on specific symptoms, timing of pregnancy, and related examinations. Generally, it is possible to take vitamin preparations or traditional Chinese medicine aimed at symptomatic treatment. In the mid to late stages of pregnancy, there are generally more options for choosing medications compared to the early stages, where primarily vitamin supplements are selected to help restore body functions.
