I woke up this morning with a slight headache and I asked my self why am I having headache lately? Now the thought came to me when you over stressed yourself there's the tendency of having headache , when you have alots running through your mind, having difficulties at work place, business environment and beyond, your body tends to react circulating through your nerves and heart and before you know it, pains on the chest extending to the head and result to headache.
You feel better when you think less and eat healthy.
