According to foreign media reports, a new study from Harvard University's Chen Zengxi School of Public Health (Harvard TH Chan School of Public Health) warns that if you are one of millions who are prone to migraines, don't drink another cup of coffee. Their findings were published in the American Journal of Medical Science.

The study assessed caffeine and its effects on people who are prone to migraines. Although caffeine does not necessarily cause migraines, the risk of migraines increases significantly after a few cups of coffee.

Caffeine is widely used in the treatment of headaches, so some over-the-counter painkillers for headaches are mixed with caffeine. However, a newly published study has found that caffeine may eventually make things worse, especially for people who are less tolerant to the popular stimulant.

The study, led by Elizabeth Mostofsky, an epidemiology lecturer at Harvard's Chen Zengxi School of Public Health, found that drinking three caffeinated drinks a day-coffee, tea, soda or similar-increased the risk of migraines.

It is reported that a total of 98 people participated in the survey, mainly whites and women who began to have headaches at the average age of 16. The volunteers' diary analysis showed that caffeinated drinks really affected their self-feelings, but their effects were only shown when they were consumed in large amounts.

In particular, the team found that drinking one or two cups of coffee or caffeinated drinks a day had no effect on the health of migraine patients. But if they had three or more drinks after that, they were more likely to have a headache.

However, excessive consumption of caffeinated drinks is not the only cause of severe headaches. If caffeine drinkers take the stimulant for a long time and then suddenly start reducing their intake, they are at a very high risk of getting a headache. The study points out that people need to control their intake and maintain consistency to avoid sudden and drastic changes.
