Does anyone know how to relieve a headache without taking any sort of medication?

আপনি can stay in a dark room অথবা cover your eyes for 15 to 20 minutes
also আপনি can drink some চা if আপনি like

Stop using anything electronical, drink lots of water, lie down in a dark room in complete silence and try not to think. This is what I do and it works :)

Try doing yoga অথবা meditating ..imagine that your are the lotos and clean your aura.

Drink lots of water. Headaches are often caused দ্বারা lack of moisture in the brain. অথবা something like that. (derp-level biology)

Lay down for a while. You'd be amazed how much a little rest can help. Opening up a couple of windows helps a great deal to.

But in the end, unless you're allergic অথবা something like that, I would উপদেশ আপনি to take an asperin. The effects of asperin kicks in after about 30 minutes. Always works for me. On a সেকেন্ড thought, take in the aspirin right away, and perform the above things I mentioned. That oughta be the best way to get rid of a headache.

Don't worry, medicine isn't that bad. Unless আপনি have an allergy.

Good luck.
