A recent study examined the relationship between sodium (salt) and duration and severity of migraine attacks. The levels of sodium were measured in 24-hour urine test of 262 participants aged 36 on average. The researchers found that a higher 24-hour urine sodium level was related to a longer duration of migraine headaches and a higher severity (measured by the Migraine Headache Index Score).
However, this finding doesn’t mean that a high sodium intake can cause migraine or worsen its symptoms.
Whether the reduction of sodium intake can improve the symptoms of migraine and how exactly the relation between sodium and migraine works, are the questions for further investigation.
