The need to sleep sitting up in pneumoconiosis is often indicative of disease progression or exacerbation. As pneumoconiosis progresses, diffuse fibrotic changes in lung tissue worsen, easily complicating chronic bronchitis and emphysema, and may even lead to pneumogenic heart disease. When pneumoconiosis is accompanied by pneumogenetic heart disease in the later stages of pneumoconiosis, the pneumoconiosis patient’s dyspnea is significantly aggravated when lying down, whereas adopting a sitting position can make his/her respiratory condition smoother than when lying down. Pneumoconiosis, which can also be called pneumoconiosis, mainly refers to diffuse fibrotic changes in lung tissue caused by prolonged dust inhalation in the living environment or occupational activities of an individual, with common symptoms such as coughing, chest pain, and dyspnea. As the disease progresses, the dyspnea may gradually worsen. When the pneumoconiosis patient progresses to the middle or late stage, he/she can often be combined with pulmonary heart disease, which causes further decline of cardiopulmonary function and aggravates the symptoms of dyspnea. When the pneumoconiosis patient lies down in this stage, it is easy to aggravate the burden of the heart and lungs, which leads to aggravation of dyspnea, so he/she mostly adopts the sitting position or semi-recumbent position. If pneumoconiosis patient’s dyspnea aggravates, he should go to the hospital in time and improve the examination and standardized treatment under the guidance of the doctor.
