ELI5: What's it like inside an aurora, aka The Northern Lights?

I know the Norther Lights are caused by the Earth's magnetic field funneling solar radiation into the poles, where it causes the upper atmosphere to glow like a fluorescent light bulb. But what is it like inside the glowing part? Would it be dangerous? Apart from glowing how would it differ from the surrounding air?

The glowing is very diffuse. You probably wouldn't notice much if you were inside it.

But the solar wind is throwing out vast amounts of energy. It's dangerous to be exposed to that for long periods - big problem in sending people out to Mars for example with the time they'd be exposed to that.
