I think the wind affects people because we are warm blooded so when it's not windy we create our own little area of warm air around us which only gradually dissipates but if it's windy this air gets blown away much more quickly. So it really only applies if you don't wear windproof clothing.
Plants are less affected because they don't generate their own heat (I think?).
