No. This is a pervasive myth, and occasionally a study will claim a correlation between the full Moon and hospital admissions, crime, psychiatric episodes, suicide or just about anything else.

The explanation usually offered for any imagined lunar effect is that the Moon’s gravity is exerting a tidal force on the water in our bodies, which affects our state of mind. But the Moon’s gravitational pull is weak and only affects the tides because the seas are huge bodies of water.
A mother exerts 12 million times the gravitational pull on the baby in her arms than the Moon does, simply because she is a lot closer.
