Colds, also known as upper respiratory tract infections, occur in the fall and winter and are common upper respiratory tract infections, mostly caused by viruses and, to a lesser extent, by bacteria, and can usually be cured on their own. Do not drink alcohol after a cold, because drinking alcohol can aggravate the symptoms of the cold and cause recurrence of the disease. Drinking alcohol after a cold will aggravate the congestion and dilation of the nasal mucous membrane, increase nasal secretions and further aggravate symptoms such as runny nose and nasal congestion, and drinking a lot of alcohol will cause headache, nausea, vomiting and other symptoms, which will increase the load on the body and lead to a longer treatment period and the possible emergence of new diseases. The immunity and resistance of the body are reduced after a cold, and drinking alcohol will also reduce the functions of the body, which is not conducive to the recovery of the body. Some antibiotics, such as cephalosporin antibiotics, can react with alcohol in a double-sulfur-like manner, resulting in palpitations, chest tightness, difficulty breathing and other symptoms, which can be life-threatening in severe cases. Although drinking alcohol can promote blood circulation while speeding up the metabolism of pathogens, its side effects are even greater, causing accelerated blood flow to the heart, liver and other organs, which can easily lead to the occurrence of sepsis, bacteremia, etc. Drinking alcohol after a cold will do more harm than good, not only will it not help the body to recover, but it will further aggravate the disease. After a cold, you should actively take oral medication and avoid drinking alcohol to avoid adverse consequences.
