Lack of sleep may cause headaches in patients for several reasons: First, if it is said that lack of sleep, poor sleep quality and the brain is in a fatigued state, there will be headaches, dizziness, lightheadedness, weakness, slowed reaction, memory loss and other symptoms. The second aspect is that if the patient has a past history of migraine or tension headache, lack of sleep can also trigger the onset of headache symptoms, so patients who do not get enough sleep are more likely to have headache problems. Thirdly, sleep deprivation may be caused by irregularities in life, or frequent late nights, frequent night shifts, etc., resulting in disturbed sleep patterns. It may also be due to some bad habits before bedtime, or related to the patient’s personal psychological factors, such as emotional tension and stress, which may cause lack of sleep.
