How Bioelectrical Impedance Analysis Works
- Electrical Signals: The watch has electrodes that send harmless electrical signals through your body when you initiate a body composition analysis.
- Resistance Measurement: Fat, being less conductive than water and muscle, will resist the passage of electrical signals more than lean tissues will.
- Data Interpretation: The watch’s algorithms interpret these resistance readings along with other metrics like height, weight, and age to provide insights into body composition.
Factors Influencing Accuracy
Several factors can affect the accuracy of the Samsung Watch’s body composition readings:
- Hydration Levels: Body water content can significantly influence impedance measurements. Dehydration or overhydration can lead to skewed results.
- Time of Day: The readings may vary based on the time of day due to hydration status and activities. Morning readings might differ from evening ones.
- Skin Temperature: Temperature variations can alter resistance levels. Warmer skin can conduct electricity better, potentially affecting the readings.
- Physical Activity: Engaging in strenuous activities before taking the measurements can lead to variations in water retention and muscle state, impacting results.
