Feeling dizzy and sleepy in the morning can be caused by physiological factors as well as disease factors. Physiological factors are mostly caused by poor night rest and poor sleep quality. Disease factors are mostly caused by snoring, insufficient blood supply to the brain, abnormal blood pressure and upper respiratory tract infections. 1. Physiological factors: most of them are caused by insufficient sleep at night, which may be due to insufficient sleep duration or poor sleep quality, which will lead to dizziness and sleepiness in the morning after waking up, which can be improved through sufficient rest or recuperation. 2. Snoring: people who snore are prone to sleep apnea, which can cause cerebral ischemia and hypoxia, and can lead to dizziness and sleepiness in the morning. 3. Insufficient cerebral blood supply: this is mostly seen in the elderly group, due to the relatively slow blood flow during the night sleep, it is easy to have insufficient cerebral blood supply, which will also lead to dizziness and sleepiness after getting up. 4. Abnormal blood pressure: high or low blood pressure may cause dizziness and drowsiness, and in severe cases, there are also symptoms of headache, after monitoring blood pressure, if you find that the blood pressure is not normal, you need to consult a doctor in time to avoid delaying your condition. 5. Upper respiratory tract infections: If you get cold during the night sleep, the next day will also appear dizziness and drowsiness, and will be accompanied by a runny nose, sneezing and other cold symptoms. Therefore, the causes of dizziness after getting up are very complex, and need to be combined with the patient’s accompanying symptoms for differential diagnosis to clarify the cause of the disease after systematic treatment.
