How it works
Dehydration reduces blood volume and can cause cerebral vasoconstriction. Restoring fluid and electrolyte balance corrects this rapidly.
Most effective when dehydration is the underlying cause. Add electrolytes (sodium, potassium) if also sweating or in heat.
A 2004 RCT found water ingestion led to significant headache relief within 30 minutes. Effect size was comparable to common analgesics.

“Some improvement but not as dramatic as I hoped. Might need longer to see full benefit. Still continuing.”
