A system and methods are provided for simulating a fair weather electric field in an environment to promote the well-being of a subject. A converter provides a DC output to generate a DC electric field in between positive and negative electrodes in an environment, where the positive electrode is proximal to a positive part of a subject and the negative electrode is proximal to a negative part of the subject. An electric field detector measures and transmits data about the strength of the actual electric field in the environment. A microprocessor receives the data and compares the information to the parameters of a fair weather electric field to direct the function of a pulse width modulator, modulate the DC output and thereby simulate the fair weather electric field in real-time. Means are provided for filtering out over-voltages, pulses and over-currents to ensure the controlled modulation of the DC electric field.
