Heavy work involves activities that engage the muscles and joints of the body, such as pushing, pulling, and lifting. These types of activities help regulate the sensory system and can have a calming effect. Some examples of heavy work activities include carrying heavy objects, pushing a cart or stroller, pulling a wagon or sled, climbing, and jumping. If you notice a child having a hard time, you can ask them to help you with a heavy work activity to see if it helps. For example, wiping the table or stacking chairs.
