Antibacterials for colds? Re! Viral colds are subdivided into common colds and influenza, and most cold patients do not need to take antibacterial drugs. This is because more than 90% of colds are caused by viruses, and antibacterial drugs are only used to fight bacteria; they have no effect on viruses. Cold infusion faster? Wrong! Fluids do not necessarily make a cold go away faster. The main purpose of fluids is to relieve or reduce the pain of a cold and to keep the patient’s body hydrated enough to have the stamina to fight the cold virus. Over-reliance on fluids not only fails to shorten the duration of the illness, but also carries the risk of allergic reactions as well as phlebitis. Covering up sweat from a cold can help recovery? Re! Covering sweat is not suitable for all colds, but only for the initial wind-cold cold has a certain effect. The symptoms of wind-cold cold are coldness, lack of sweating, mild fever, headache, body ache, nasal congestion, runny nose, and coughing up sputum that is thin and white in color. However, if you cover too much will also be counterproductive.

Moderate, mild, gentle exercise can be, but excessive sweating after exercise, it is easy to lead to the human body, and strenuous exercise to increase physical exertion, so that the ability to fight disease decreases, the virus is more likely to take advantage of the weakness of the “into the”. Cold and flu superimposed on the medication faster? Wrong! Some people in the cold, will buy fever, cough and several kinds of drugs together, such as ibuprofen, paracetamol or cough syrup, to relieve the symptoms of cold. Taken in excess or mixed synergistically, the stacking effect of the drugs can cause liver damage. Many medications often contain the same ingredient, and it is easy to overdose when several are taken together. Remaining cough after a cold, immediately use medicine? Wrong! Many people after a good cold after the remaining cough, this time there is no need to rush to use the drug, the cough can be relieved, but if more than two months have not been relieved, it is best to go to the hospital. The first thing you need to do is to avoid drinking alcohol while taking cold medicines, because alcohol can interact with many cold medicines, which may not only reduce the efficacy of the medicines, but also produce toxic side effects, which can be life-threatening in serious cases. If the cold medicine containing paracetamol can be catalyzed by alcohol as a toxic substance, aggravating liver damage. 2, do not arbitrarily increase the dosage of drugs Some patients with severe colds in order to recover as soon as possible, will take a large dose of one or more cold medicines.

Different symptoms, different causes of colds, should choose a different treatment focus of the drug, so that the right medicine, the efficacy is more obvious. 4, do not exercise strenuously Cold and flu patients often hear “more rest, drink more water” advice, but most people only remember to drink more water, but ignored the rest, wrongly believe that exercise at any time can enhance resistance. In fact, cold and fever, the person’s metabolism is stronger than usual, energy consumption, resistance is weaker, this time if you strengthen the movement, the effect is counterproductive. Proper rest, reasonable diet, the right medicine is the right way.
