Patients with colds should always pay attention to keeping warm and not catching cold, so as not to worsen the condition. Usually, they can take some cold medicines, which can clear heat and detoxify. If the condition is severe, it is recommended to take medication under the guidance of a doctor. Normally, drinking more water and urinating frequently can effectively expel some viruses from the body through urine, alleviating the symptoms of a cold. In terms of diet, eating more fresh fruits and vegetables, such as apples, bananas, and green vegetables, can effectively improve symptoms. Also, spending more time in the sun can help increase the body's immunity.
