1. A fluid stimulation system comprising:
a mobile, wearable apparatus comprising a chamber sized to fit around a body part of a subject and to stimulate fluid loss in the subject, wherein the fluid is sweat, and wherein at least a portion of the chamber provides a clear volume of air between the body part and one or more walls of the chamber upon receipt of air flow and subsequent expansion of the chamber, the chamber comprising an inlet and an outlet and the chamber being configured such that an air flow passes through the chamber from the inlet to the outlet to thereby create a controlled environment around the body part of the subject for stimulating fluid loss in the subject;
first and second relative humidity and temperature sensors, wherein the first relative humidity sensor is operably located at the inlet and the second relative humidity sensor is operably located proximate the outlet; and
a controller configured to monitor and control conditions of the controlled environment around the body part of the subject, the controller being communicatively coupled with at least the first and second relative humidity and temperature sensors and configured to calculate a sweat rate within the chamber based, at least in part, on data received therefrom and control and adjust inflow air temperature and/or air flow rate into the chamber based, at least in part, on the calculated sweat rate.
