User: How can I quickly treat a headache?
Assistant: Occasional headache is something that is more annoying and causes discomfort than concern. To quickly relieve a headache, make sure you are in a well ventilated space, drink a couple glasses of cold water, take some caffeine like coffee or cola, stare at something green like a plant for ten minutes, and close your eyes or lie down for about ten minutes. You can also twist your head left to right, right to left, then stare up, until you get a sigh or a yawn.
