Research by Exeter University could change the way buildings are designed - to eliminate tiny vibrations which can make people feel anxious or unwell.
It's been known for some time that very tall buildings which sway slightly in the wind, or bridges which wobble, can give people a form of motion sickness.
Now a team from Exeter and Bath universities will use simulators to recreate vibrations which people don't even notice, but can have an effect on their bodies.
The information will be used to make sure buildings are designed and constructed with people's health and well-being in mind;.
