Poor sleep can affect the blood supply and oxygen supply to the brain, so it can lead to headaches. When the brain is not fully rested, it consumes more oxygen and tends to produce too much harmful substances, which affects the metabolism of the brain, so a more pronounced pain sensation will occur. If there is vascular headache as well as neurological headache, the headache will be aggravated when there is poor sleep. Tension headache may also induce headache as well as stress headache in patients, especially in the presence of brain tumors, meningitis, etc. If there is a history of head injury, the head can also be affected during insomnia, and the headache can be aggravated.
