📌 putting this here so that I remember.

I woke up on my day off with a headache for what seems like no reason. I did everything I thought right: balanced breakfast, coffee, advil, plenty of water. Annoyed. At around noon I took a bath and put my head under.

Instant relief. Why!

Well maybe it's because the blood vessels are mildly dilated. Maybe the water pressure affected it. I doubled down and put ice and cold water in a bowl and dunked my whole head in. It felt fantastic. Maybe I'll do that more often.
