-Why health issues get aggravated at New Moon and Full moon?

-Is it some sort of Black magic? Here is the scientific explanation of it.... 

We all know that, moon phases has its effects over sea water as high tide at Full moon and low tide at New moon.

If thousands kilometers large sea, we can visualise these high tide and low tide of half a kilometer difference. 

Similarly As Earth is covered with 70% of water, our body constitutes 70% water.During moon phases, our body water also gets changes like high tide and low tide but they are imperceptible to our eyes as far such a large sea changes are of only half kilometer for our body, we can't perceive them visually. But for sensitive individuals or all people, these such mild alterations also alter mineral concentration of different body fluids and these people can feel different sensations and symptoms. 

So, no need to worry. 

If you are getting such alterations, feel lucky about such an amazing alignment of your body to the Universe. Thank you...
