Sometimes the best way to help your clients internalize key health lessons is to have them act them out. For this activity, you will need a free doorway in a low-traffic area, with available space on either side of the door. The door to your office or conference room may be perfect. You will also need some balloons, tape, and 4 different colors of bandanas (or another tool that you can use to mark participants into different teams).
Begin by bringing your participants into the hallway and explaining that the group is going to model the flow of blood through an artery. Then divide everyone into four groups.
One group will represent LDL cholesterol. They will carry balloons that they will attach to the edges of the door as they go past. These balloons will represent growing LDL deposits.
A second group will represent HDL cholesterol, which will remove LDL balloons as they go past and help to clear the arteries.
A third group (the largest) will be blood, trying to move through the door.
A fourth group will link arms to represent blood clots and try to move through the doorway in groups,
Begin by having the LDL and blood groups move through the door in waves. Point out the delay prompted by LDL people taking time to stick their balloons to the door and how this action impacts blood flow.
Have a second round of blood, LDL, and HDL move through the doorway, carrying out their tasks, then discuss how the blood flowed this time.
Then, once the door is pretty covered in balloons, discuss the parallels of the door to an artery in a person with high blood cholesterol. Add a few blood clots to the group and have the teams move through the door again. What happens when a blood clot clogs the artery? What would happen to a person if this occurred in his or her body?
Have everyone take down their balloons and return to the classroom for a full activity debrief, answering any questions that they may ask and highlighting the roles of HDL and LDL cholesterol on the flow of blood through the arteries.
