External signs of a cold
A typical symptom of the common cold is profuse watery mucous discharge from the nose. Initially, they are transparent, but after a few days they may become dark (yellowish or greenish) and dense. The darkening of the discharge indicates that a bacterial infection is intensively operating in your body, and in the treatment of which an antibiotic is prescribed.
Another obvious sign of a cold is soreness and sore throat, which after 2-3 days develop into a cough. But the cough in no case can not be suppressed, because it clears the lungs of mucus and bacteria. As a rule, cough is first dry: it is considered unproductive, because it does not bring relief, it flows like a paroxysmal and very tiring. A dry cough is very irritating to the respiratory tract, and besides, it can cause complications such as rupture of the mucous membrane and vomiting. After taking the drugs that thin the sputum, the cough becomes wet. With such a cough, sputum withdraws and the pathogens are removed from the body, as a result of which the healing process is accelerated.
The main symptom of a cold is fever or fever.According to the level of increase, the temperature is divided into hyperpyretic (more than 40 � C), febrile (from 38 � C to 40 � C) and subfebrile (37 � C - 38 � C). Heat is accompanied by an acceleration of metabolism, an increase in the breakdown of protein compounds and other substances, as a result of which heartbeat and breathing become more frequent, headache and muscle pain occur. Most pathogens do not withstand a temperature of 38.5-40 � C, so it would be possible, after waiting for the body temperature to rise to these indicators, to calm down and calmly wait for the body to defeat the illness, but, unfortunately, this should not be done, because too high a temperature is not safe for the man himself. Often the cold is accompanied by low body temperature: this indicates loss of strength, weakened immunity and low body resistance.
Additional external signs of a cold include lethargy, fatigue and lack of appetite.
