Abstract
Technologies for measuring a hydration level of a user includes a hydration measurement device having an arm position sensor and one or more reflectance sensors. The hydration measurement device generates sensor data indicative of a position of a user's arm using the arm position sensor. The hydration measurement device performs reflectance measurements with the reflectance sensor(s) at a first position that is determined based on the sensor data and a second position that is raised relative to the first position that is also based on the sensor data. The hydration measurement device determines a hematocrit of the user's blood based on the reflectance measurements and determines a hydration level of the user based on the determined hematocrit. Other embodiments are described and claimed.
