I am not a very religious person - I learned about my religion, but I don't know that much. I simply believe that there is a greater power than human out there, someone who created us and gave us opportunity to live. By learning Islam I know that power is "Allah" and He command us, human, to do prayer 5 times a day which we called "shalat". Sajdah is one of the position in shalat which actually I didn't really pay attention to its benefits until I had a headache.
Based on what I read here, more blood supply to our brain will help us increase our cognitive abilities which related to our memory, vision, hearing, concentration, and psyche. Doing sajdah regularly also will give us less headache and less psychological problems. There are several other benefits of sajdah, should you want to learn more about it do not hesitate to open the link.
My concern here is not to tell people who read this to do shalat or to encourage non-Islam people to learn about my religion. I simply want people to know that there is another way to solve your headache besides taking medicine - maybe it would not give a big or a direct effect, but at least if you try sajdah, your brain will get more blood supply which it might desperately need.
Yet, I only write or recite something I truly believe. And I have no doubt He command us to do sajdah 34 times a day for our own good.
