The differences between wind-heat cold and wind-cold are the season of onset, the characteristics of onset, the characteristics of sweating and the characteristics of secretions. Season of onset: wind-cold and flu occur mostly in winter and spring, but wind-fever and flu occur mostly in summer or the border of summer and fall. Characteristics of onset: Patients with wind-cold flu usually have light fever, but patients with wind-heat flu usually have heavy fever. Sweating characteristics: wind-cold and flu often have no sweating, while wind-heat and flu often have obvious sweating. Characteristics of secretion: Most of the patients with wind-cold flu have thin sputum with white color, while those with wind-heat flu often have yellow sputum with sticky consistency. If you have a cold or flu, you need to be diagnosed by a doctor under the guidance of evidence-based guidance, and need to standardize the treatment to avoid delaying your condition.
