Smoking can cause a wide variety of health issues, and headaches seem to be one of them. Studies suggest that smokers may be twice as likely to develop headaches as non-smokers, especially in adolescence. Migraines and cluster headaches especially seem to be more frequent in smokers. In addition, smoking a higher number of cigarettes seems to cause migraines more frequently.
The likely reasons? Nicotine in tobacco products causes blood vessels to constrict, possibly leading to migraines. Smoking may also directly stimulate nerves in the back of the throat, leading to head pain.
Finding ways to quit smoking can be an effective strategy for preventing headaches, as well as improving your overall health.
