I. Lifestyle triggers 1. High mental and psychological stress, depression or drastic mood changes: The fast-paced social environment, the discomfort and pressure of life and work, and the cautious consideration of various affairs and relationships often make people’s brains nervous and depressed, which leads to the occurrence of migraine. Emotional changes are one of the significant triggers of migraine. However, it needs to be further explored whether mood changes are the aura of migraine or whether they directly trigger the onset of migraine. 2. Improper diet: Certain foods can cause changes in the body’s internal environment, leading to the occurrence of migraine. 3. Excessive exercise: 4. Irregular sleep: lack of sleep, too much sleep, irregular sleep, etc. 1. oral vasodilators 2. contraceptives 3. hormone replacement drugs 4. frequent use of ergotamine, opioids, tretinoin and other single-ingredient painkillers (barbiturates, caffeine, isooctenamide) 3. climate triggers Wind, cold, humidity, heat and other climates and drastic weather changes can easily trigger migraine. Humidity and heat tend to cause mood swings, irritability and loss of appetite, resulting in disorders of qi and blood flow and triggering migraine. Wind and cold tend to damage the body’s yang energy and cause blockage of the meridians, thus triggering migraine. Special note: Migraine patients should avoid cold food and cold. 10 minutes after receiving cold or cold stimulation can cause headache. In winter, forgetting to wear a hat and exposing your head to cold air, swimming in cold water, or eating ice cream or cold drinks can all cause cold stimulation headache. The mechanism may be related to the vasodilation disorder caused by the dysfunction of the autonomic nervous system. It was found that in the cold environment, the bilateral temporal arteries and their branches spasm and become thin before the headache, and the arterial rage, filling and pulsation are enhanced during the headache period. After eating cold drinks, the cold stimulation of the tongue and oral mucosa by cold drinks reflexively causes spasm of the temporal arteries, and when the spasm reaches its maximum, it turns into passive dilation, and the blood flow impinges on the nociceptive nerve endings on the wall of the dilated arteries, triggering headache. In conclusion, external exposure to cold or eating cold drinks is the condition of cold irritation headache, and the basis of the pathogenesis is related to the physical and neurological dysfunction of blood vessels that easily induce sympathetic nerve hyperfunction. Therefore, care should be taken to stay away from cold environment and eat less or no cold drinks. 4. Environmental triggers 1. sudden change in altitude 2. change from one time zone to another within a short period of time 3. stimulation of strong light (such as TV screen, magnesium lamp, strong sunlight and other factors can cause headache due to eye fatigue.) 4. The stimulation of noise 5. The pollution of air 6. The stuffy room 7. Some strong perfume 8. Long time electromagnetic radiation (Some people working in front of the computer are prone to migraine because of electromagnetic radiation.) V. Female physiological triggers 1. Before puberty, the prevalence rate of men and women is similar. 2. After puberty, the incidence is significantly higher in women than in men. 3. Headache attacks are common when women have menstrual periods. 4. After menopause and during pregnancy, the headache decreases. Hint: Menstrual cycle changes have a direct trigger effect on migraine attacks, and this condition may be related to changes in hormone levels. The onset of some female patients is directly related to the menstrual cycle and is called menstrual migraine, a special type of migraine related to the ovarian cycle. Modern medicine believes that the sudden drop in estrogen levels (lower estradiol) during the premenstrual period causes the intracranial and extracranial blood vessels to be sensitive to the consequent changes in biochemical factors (such as 5-hydroxytryptamine and other vasoactive substances), which affects the function of target organs by interfering with sympathetic nerves, causing migraine headaches due to changes in the diastolic function of the intracranial and extracranial blood vessels in susceptible individuals. In Chinese medicine, this disease is called menstrual headache. Clinical treatment is mainly based on regulating qi and blood, so that qi and blood can be harmonized and clear orifices can be nourished, then the pain will stop.
