When you have a cold, covering your sweat with a blanket is not useful for treating the cold, but it will probably aggravate the cold. After sweating, the pores will be open, and cold air and cold air will enter the body along the pores, so it is easy to get cold, and once it happens, it will aggravate the symptoms of cold. If the phenomenon of wind-heat cold occurs, covering sweat will also aggravate the wind-heat cold situation. Therefore, you should never use the method of covering sweat during the cold to treat it, and you must choose the right cold medicine to relieve the symptoms according to the cold situation. For example, if you have a stuffy nose or runny nose at this time, you can use Aminophenol Pseudo-lax Dispersible Tablets, Pediatric Aminophenol Flavonamide Granules, or Cold and Fever Granules for relief if it is serious. If you have a sore throat, you can use Pudilan Anti-inflammatory Oral Liquid or Four Seasons Anti-viral Combination for anti-inflammation. If you have cough or phlegm, you can use Ambrotero Oral Solution, Pulmonary Cough Compound, or Compound Fresh Bamboo Leach Liquid for treatment.
