How does quantum tunneling work?

i mean, a particule can go throught matter because, it´s going too fast, or it can travel trought the gasp in our cells?.i mean, in that way why arent we change by this objects. like. Hows a particule can go so fast that can traverse you without been notice.Ex:- you can feel photons (light) but you can´t feel neutrons so.....

The particle doesn't tunnel through a barrier per se. It isn't even a particle while traveling, it's a wave function with a probability distribution along that wave. That distribution tells us how likely the particle is to be found at any point of the wave once we measure it. Measuring the particle collapses the wave function and makes the particle behave like a particle and not a wave.

In this state, the particle cannot travel through the barrier. However, there is a portion of the wave function that exists on the other side of the barrier. It is much less likely that we measure the particle as being there, but it isn't impossible to do so.

So sometimes when the wave function collapses upon measurement, the particle will have appeared to have "teleported" to the other side of a barrier.

I've simplified several things that have a lot more nuance to them, but this is the basic gist.
