Water has nothing to do with it. Gravity pulls on all matter. That said, the moon does not affect us.

It has a huge effect on a few humans. Every so often, maybe once a month, it turns humans into werewolves

Not really. ?

I have always wondered about the same thing...maybe it would be minuscule, but I have not seen research on the matter!

As I recall, the word lunatic is derived from the belief that some people do act a bit strange under a full moon. My wife says she can verify that!

When I was an RN, the full moon nights weren’t always busier...but what DID come in was definitely crazier. Than usual.

I hate being pulled this way an that

It has damn all affect.

When the moon is directly overhead its gravitational attraction would make a 100Kg person seem half a gram lighter, and when its on the opposite side of the Earth half a gram heavier.

Take something and drop it. The moon has no significant effect on how quickly it drops, or in which direction. Does it angle sideways if the moon is on the horizon? No, it doesn't.

The oceans are vast. We people individually are just little shits, I think too small to measure if there is an effect, and if there is, all creatures adapted a long, long time ago. Now, if we lived in one of Jupiter or Saturn's moon, you might be talking about something.

No effect and no way to test anything beyond basic correlation: [csicop.org]

It probably doesn’t effect us much cuz the water In The ocean is free floating where as all the water in our body is part one solid thing well mostly solid lol.

None. It only affects tides because water is distributed across Earth. Its the differential force across a large distance that causes tides, a human body can have a differential of about 7 ft max, bodies of water have a differential the width of the Earth.

Every few weeks I tend to drift to the left for a few hours....

Statistically, there are higher rates of violent crimes during a full moon.

This is not really true, but this is still extremely funny

Why did you ask about the effect it has on water? It has a gravitational effect on everything.

You might want to watch this:

I have always thought that as humans we disavow anything that we absolutely cannot quantify based on personal experience or knowledge. I have come to the personal conclusion that there are things I can't prove or disprove that may affect life and the planet. So I have become able to say, "gee I really don't know" I figure my comment is no more valid than the naysayers or proslytites.

We are actually about 70% and I am convinced that we are affected. Why? First of all, there is a reason crazies are called lunatics and it is not just a myth. A friend was the head nurse at a NYC emergency room and told me, each time there was a full moon "They're jumping." A lot of suicides and suicide attempts. Police officers know it is going to be a "bad night." I have also very recently begun to really think there is something to "Mercury in retrograde." The last bout was an awful time for me and just about everyone I know.

I read an offering by Bob Berman that said it has no affect on us. I can't offer the source, other than I remember it was Bob Berman..

If it did it would be extremely minuscule.

After I graduated from college, I worked in a CT state institution for three years. There were many times someone on our staff would turn to another and ask "was it a full moon last night?" and it was !!! Maybe the effect is only obvious on those already a bit "off", but we observed this often.

Not much ... but...
