Lack of sleep: due to staying up late, insomnia, anxiety, etc. caused by excessive fatigue, decreased energy, thus triggering the brain local blood supply is insufficient and headache yawning. 2. Cerebral arteriosclerosis: patients with excessive deposition of lipids in the blood vessels leading to cerebral arteriosclerosis, cerebral blood vessel narrowing affects the blood supply to the brain, yawning and headache symptoms may occur. 3. High blood pressure: when the patient’s blood pressure is too high and fluctuates too much, due to the long time spasm of the blood vessels in the brain, it is easy to cause insufficient blood supply to the brain, which will lead to headache and yawning. 4. Cerebral hemorrhage: after cerebral hemorrhage, the blood will compress the nerves and brain tissue, resulting in brain tissue damage, causing lack of oxygen in the brain, respiratory center excitability increases, and there will be a headache and yawning performance. The cause of headache yawning is more complex, it is recommended to exclude physiological causes and then consult a doctor in order to clarify the diagnosis and take active treatment.
