In everyday life, if you want to prevent colds, you need to pay attention to keeping warm and avoid catching cold from the wind. The most important thing is to actively participate in physical exercise to enhance your physique and improve your own resistance, which is crucial. To enhance your own resistance, you can improve it through some small details in your daily life, such as eating more fresh fruits and vegetables, supplementing vitamins, and also making sure not to stay up late at night, ensuring sufficient sleep to enhance your resistance. You should also pay attention to personal hygiene, washing your hands before meals and after using the toilet, and often open windows for ventilation to keep the indoor air fresh and circulating. Additionally, it is necessary to regularly disinfect the bedroom to eliminate bacteria and avoid bacterial infections. Also, pay attention to eating more warm, soft, and easily digestible foods.

Can you drink alcohol if you have a cold?

It is not recommended to drink alcohol during a cold. This is because alcohol can suppress the central nervous system and affect the absorption of medications, especially cephalosporin drugs. One must not drink alcohol as it can pose a life-threatening risk. Whether it is beer, Western liquor, or strong spirits, none should be consumed. Since a cold itself can cause symptoms of fatigue and weakness, adding alcohol can potentially worsen these symptoms. Additionally, consuming alcohol while on cold medications is not advised, as it can lead to poor mental focus, and alcohol can exacerbate the symptoms of a cold.

Cold with nasal congestion, fear of cold, and sweating is what kind of cold?

A cold, also known as an upper respiratory tract infection, often occurs due to decreased immune function, inadvertent exposure to cold, or infection by certain viruses, bacteria, or pathogens, leading to clinical symptoms such as nasal congestion, runny nose, fever, sore throat, and chills. When a patient with a cold has a fever, it invariably causes a sensation of chilliness throughout the body, along with cold extremities. If such patients are given appropriate antiviral, heat-clearing, detoxifying, and fever-reducing medications for symptomatic treatment, usually after the fever subsides, a process of sweating occurs, which is very common in clinical practice, especially in cases of febrile colds. Therefore, in clinical practice, regardless of the type of cold causing the fever or symptoms like nasal congestion, it is essential to provide timely symptomatic treatment with medications to alleviate these uncomfortable clinical symptoms.

There are several types of common cold.

Traditional Chinese medicine classifies the common cold based on the different external pathogenic factors a patient encounters, which can be categorized into cold-induced common cold and heat-induced common cold. A cold-induced common cold occurs when a patient is invaded by cold pathogens, while a heat-induced common cold is when a cold is contracted after exposure to external heat pathogens. In modern medicine, also known as Western medicine, the common cold is further classified into the ordinary common cold, primarily caused by viruses, bacteria, and mycoplasma infections, and the epidemic influenza, mainly caused by the influenza virus. Generally speaking, both Chinese and Western medicine employ different treatment methods and medications specific to the pathogens involved in the cold, and both approaches can be very effective in treating the condition.

Symptoms of gastroenteritis

Generally, in cases of gastrointestinal-type colds, in addition to some common cold symptoms, there are also symptoms related to the digestive system. These include a decreased appetite, anorexia, nausea, vomiting, diarrhea, and even constipation. There is also discomfort in the stomach and intestines, along with symptoms of indigestion. It is important to be aware of gastrointestinal colds which, apart from symptoms like nasal congestion, sneezing, runny nose, and coughing up phlegm, also involve gastrointestinal symptoms. In addition to taking cold medicines, it is necessary to use medications that regulate the gastrointestinal tract to treat and alleviate these symptoms. It is advisable to eat smaller meals more frequently, not consuming too much at once to avoid overburdening the digestive tract and causing indigestion.
