Waking up at night may be caused by excessive mental stress, mainly due to brain fatigue causing plant nerve disorders, other diseases can also cause similar symptoms, such as cervical spondylosis, pulmonary heart disease. Patients suffering from cervical spondylosis may wake up at night because the herniated discs compress the vertebral arteries, thus causing mild ischemia and hypoxia symptoms in the cranial parts. If hypertension or pulmonary heart disease affects the normal pumping function of the heart, the symptoms of suffocation will occur after waking up at night, and some patients will have a violent cough and cough up pink foamy sputum due to the aggravation of the symptoms. The presence of cranial vascular diseases, such as cerebral ischemia and cerebral thrombosis, can cause similar symptoms, as local thrombosis causes compression of brain tissue.
