We know that by science, man is made up of 70% of water and 30% rest of the elements. And same is the case with mother earth. Added to that we know, tides and waves are a big cause of the shifts and phases of moon. Which is called "the gravitational pull".

What happens when earth moves like that? Does it effect humans? Ask science... And the answer is , it does effect activities going on in our alpha parts of the brain, of which is again mostly fluid.  And it helps you to stay calm, triggers you when you loose focus. 

After doing some part of my research on this, I got convinced that it does effect us directly and indirectly as well. Our emotions, energy and feelings might get on peak on full moon and might be at lower levels during other phases. We just need to have control over them by making best use out of that particular phase.
