I don't think our body is very sensitive to air pressure. There are some people who report to be triggered during flight ascent or descent, but there the pressure change is much lager and at a higher rate than during a weather change and the triggering may be due to a change in oxygen uptake.
However, there is more to weather change than just air pressure. Here, on the north side of the alps, we sometimes get a weather phenomena call Föhn. It is a dry, hot wind coming down the alps, sometimes reaching storm force in the valleys but farther away over the plains it usually goes over the lower layers of air. Many people get (ordinary) headaches during a Föhn period and I observe many more crazy drivers on the road. But the main difference is a change in the static electric field; from the normal 200 Volt/meter it changes polarity to -100 V/m.
It could well be that an approaching cold or warm weather front influences this static electric field, and this makes some people sensitive to weather changes.
Just my 2 cents,
