When you wake up in the morning, your mouth is very bitter, accompanied by cough, yellow sputum, insomnia and other manifestations, most of which are caused by excessive heat, and improper diet, insufficient drinking water and other factors. In addition, it may also be caused by wind-heat cold. In daily life, you should eat more fresh vegetables and fruits, adhere to exercise, maintain indoor air circulation, and soak your feet with warm water before going to bed.
