Do clothing and hair affect the BOD POD results?

During BOD POD testing, measuring the volume and mass can majorly affect clothing, hair, jewelry, and eyeglasses. So all clients in the BOD POD testing must take off all jewelry and eyeglasses. Wear specific minimal, form-fitting clothing such as a Lycra or Spandex swimsuit, single-layer compression shorts, or lightweight jog bras, which can be worn throughout the testing without padding or wires. A swim cap is also needed to reduce any air pockets within the hair.
