What will happen if you take medicine for wind-heat cold when you have a wind-cold cold?

The treatment principle for colds caused by wind-cold is to use pungent and warm herbs to expel the pathogen through sweating and to disperse wind-cold. The medications for wind-heat colds mainly focus on using pungent and cooling herbs to expel the pathogen, and the treatment principles for the two are completely opposite. If medications for wind-heat cold are taken for a wind-cold cold, it might lead to a worsening of the trapped cold, causing mild fever, more severe headache, and body aches, along with nasal congestion and a runny nose with clear discharge. At this point, it is necessary to stop using the medication for wind-heat colds and switch to medications for wind-cold colds, or, if the condition is severe, seek a face-to-face consultation with a doctor.

How to treat a baby's cold fever

Children's heat colds generally occur in the summer when the weather is hot, and the following methods can be used to manage it: First, give the child an appropriate amount of warm water to drink. When a child catches a cold, they will consume too much water from their body. At this time, replenishing water can improve the child's symptoms. Second, take some antipyretic and heat-clearing drugs. These drugs are effective in alleviating symptoms such as fever, nasal congestion, and cough caused by heat colds. Third, if the child develops throat inflammation, nasal congestion, and yellow nasal discharge after catching a cold, this might be a bacterial infection. Cephalosporin antibiotics can be used, but it is best to take the child to the hospital for tests like a complete blood count and other examinations. Only after confirming the indications for antibiotic use should antibiotic treatment be administered.

Itchy throat and coughing, is it a wind-heat cold or a wind-cold cold?

When patients present with symptoms such as itchy throat and cough in a clinical setting, it is generally difficult to distinguish between a wind-heat cold and a wind-cold cold based solely on these symptoms. Distinguishing between wind-heat and wind-cold colds requires combining other clinical symptoms to accurately differentiate. Typically, patients with wind-heat colds are more common during the hot summers. These patients experience varying degrees of nasal congestion, runny nose, and sneezing, along with fever, chills, sore throat, and often cough up yellow sputum. On the other hand, wind-cold colds tend to occur more often in winter. These patients exhibit varying degrees of itchy throat and cough, nasal congestion, and also experience different degrees of fever, but generally do not have chills. Therefore, it is generally difficult to specifically distinguish the type of cold based on the solitary symptoms of itchy throat and cough in a clinical setting.

What to do with excessive sweating from a cold?

When you have a cold and experience excessive sweating, this situation is fairly normal and there is no need to worry excessively. Your body is in a state of rest and is metabolizing at a higher rate to combat the invading cold viruses or bacteria. During this time, it is important to keep warm and avoid exposure to wind or cold. After waking, it's advisable to drink an adequate amount of water to stay hydrated and prevent dehydration and electrolyte imbalance. Additionally, under the guidance of a doctor, you should take the appropriate anti-inflammatory and anti-infection medication, or antiviral drugs to treat the condition and alleviate symptoms like sweating.

Can you eat crab after taking cold medicine when you have a cold?

It is recommended not to eat crab after taking cold medicine. Because crabs are aquatic animals and are considered cold in nature. During a cold, it is best to avoid overly cold foods, pay attention to rest, drink more warm fluids, and follow a light, easy-to-digest diet, and to take medicine on schedule. Although eating crab will not cause poisoning, it can decrease the effectiveness of cold medicine, thereby prolonging the duration of the cold. If the cold improves, crabs can be consumed in small amounts.

How many days does it usually take for a fever to subside from a cold?

A cold, if accompanied by a fever, is mostly caused by bacterial or viral infections. Under the guidance of a doctor, active symptomatic treatment can usually reduce the fever within two to three days. It is recommended that during the fever period, one should monitor the body temperature closely. If the temperature exceeds 38.5°C, fever-reducing medication should be taken immediately to achieve the purpose of reducing the fever, to avoid febrile convulsions, especially in infants and young children whose nervous systems are not yet fully developed. If a high fever is not treated promptly, it could likely lead to febrile convulsions and may have a certain impact on the child's health. Therefore, it is advised to take fever-reducing medication in a timely manner. If the body temperature is below 38.5°C, physical cooling methods can be used at this time. Let the baby or the patient drink more water to promote excretion and enhance their resistance. Physical cooling methods should also be used regularly.
