It is a legacy from the old times, when the meeting with a threat ended with one of the only two options - hit or run.
In both cases, our body was ready for physical effort.
That is why today our heart pounds faster, our muscles tighten, we are suffused with cold sweat, and our blood pressure increases.
At the same time, all other bodily functions (e.g., welding) fall into the shade until the danger passes.
