Mechanical vibrations affect people in different ways. Depending on the point of entry, they can be hand-arms vibrations that are the main cause for the white fingers syndrome as well for other affections.

Whole body vibrations, on the other hand can affect bones, joints, blood vessels etc.

There are standards that set limits to acceptable vibrations for both hand-arms as well as whole body vibrations.
