The headache that occurs every morning when waking up from sleep is mainly considered to be due to two reasons. The description is as follows: First, it is mainly due to too much dreaming during sleep. Normal people sleep for 4-6 dreams a day, and if there are more than 4-6 dreams, the patient will be in a poor state of brain rest, when the blood vessels in the brain will be dilated and the blood supply to the brain will be insufficient, and the insufficient blood supply to the brain for a long time will cause the symptoms of morning headache. Second, it may be that some patients have respiratory sleep apnea syndrome due to their fat body mass, which is manifested by low ventilation and apnea during sleep. This can lead to a lack of oxygen to the brain and a headache after waking up, often combined with hypertension and arrhythmia symptoms, and surgery is recommended for this type of patients.
