In summer, due to the high temperatures, many people use air conditioning to cool down and avoid the heat, but in some cases, this may lead to catching a cold, triggered by the cold air, which is caused by viral infections. Currently, there is no specifically effective medication to treat it. Generally, treatment involves symptom-relief medications, such as antipyretic analgesics, compound cold medicines, and various traditional Chinese medicines. Besides medication, it is important to rest, avoid getting chilled, drink plenty of water, quit smoking, and ensure room ventilation to aid the recovery from a cold. (Specific medications should be taken under the guidance of a physician.)
