What Causes Headaches?
Does Lightening Cause Migraines?
A migraine is defined as a headache associated with intense throbbing and often accompanied by nausea, vomiting, and extreme sensitivity to light and sound. They can last anywhere from a few minutes to several days long, and the pain and disorientation can be so intense that it renders the person having one incapable of doing just about anything. Doctors aren't 100 percent sure what exactly causes them, but a new study published by the University of Toronto offers an interesting statistic: people who witnessed physical abuse between their parents were more likely to get migraines (men were 52% more likely and women were 64% more likely).
Migraines themselves are thought to be brought on by abnormal brain activity and a serotonin imbalance. Numerous studies have shown that when a person is under intense levels of stress and anxiety, their brains produce greater amounts of fear-related chemicals like adrenaline, and less of the joy-related chemicals like serotonin. According to the University of Toronto study, it's possible that witnessing domestic violence adds viscerally stressful memories to a still-developing mind. If the pattern of abuse is constant, the brain can get used to overproducing adrenaline and under-producing serotonin, which would explain why migraines can be a chronic condition for some.
