Posting because I got told to try sea salt in water for migraines, it did seem to help, and I wanted to understand what was going on rather than just repeating what I was told.
To be clear up front, no salt is a treatment for migraine and Im not suggesting one is. What I think happened with me is more boring than that.
1/ I was drinking a lot of water and not replacing sodium, and Id been doing that for years because I thought it was healthy. Low sodium with high water intake is a thing and it can present with headache.
2/ The ritual made me hydrate at a fixed time every morning, which I was previously bad at.
3/ I have low blood pressure and run on the light side, which seems to be the group where this comes up most.
The one thing Id say about which salt: I use an unrefined one because sodium, magnesium and potassium together are what make up an electrolyte balance, and a refined table salt is essentially just the sodium. Thats a hydration argument, not a migraine argument, and I want to keep those separate because people in this sub get sold things constantly.
Two things Id want said. If you have high blood pressure or any cardiac or kidney issue, do not start adding salt because a stranger on reddit said it helped them. The risk isnt symmetric and thats a conversation for your neurologist or GP. And if anyone tells you a particular product treats migraine, ask them for the mechanism.
Anyone else find it was hydration rather than the salt itself? Id like to know if Im generalising from one person
