Fluctuations in the hydration rate that can be caused by the consumption of alcohol, by the food, the sleep, the exercise, taking medication or pre-menstruation can cause variations in the results obtained.
Other causes that may cause measurement errors:
- Severe calluses on the heels or soles of the feet
- Dampness of the feet (e.g. after a bath) or if the skin of the feet is very warm
- If electrods on the scale are dirty this may interfere with conductivity
- A full bladder
- Do not wear anything on your feet – not even tights – the electrical conductivity is affected
- Medical implants such as a steel plate in the leg, an artificial hip joint, or breast implants will affect the readings although the body fat monitors are still safe to use with these conditions.
