We are all aware that it’s important to limit the amount of salt that we eat, and part of the problem is literally in our heads. High intake of sodium contributes to head pain, according to a new study that appeared in the December 11 issue of the UK’s BMJ Open. The connection between dietary salt and headaches is strong in another, separate way as well: high sodium causes blood pressure to rise, which in turn leads to headaches.
What you eat can play a huge role in the amount of headaches you have (headache frequency) and the severity of pain you experience (headache intensity). That is true both with migraines (vascular constriction and dilation) and other types of headaches (vascular constriction). Lifestyle choices and other, often environmental, factors that tend to be a direct cause of individual headache attacks are called triggers. Dietary triggers are extraordinarily common.
