Am I getting hit by neutrinos right now?

Fortunately, neutrinos are so unlikely to interact with any matter—including the atoms and molecules in the human body—that the billions upon billions of neutrinos that hit you every second have no discernible effect.

Even when it does happen, the result is merely a tiny flash of harmless light.
