Grounding exercises are things we can do to bring ourselves back to the present, to the here and now. These can be quick strategies like taking deep breaths or exercises such as yoga and meditation. Different strategies work for different people, and there is no "right" or “wrong” way to ground ourselves. The main aim is to keep our mind and body in sync and working together.
People who have experienced traumatic events, as a child or as an adult, can sometimes be plagued by flashbacks or intense memories of what happened, to the point that they feel as if they are back there, re-living the trauma all over again. A flashback is an example of being in the “there and then” rather than the “here and now,” so grounding exercises can help to bring you back.
