1. An electronic ring for monitoring Vitamin D produced in a body of a user, the electronic ring comprising:
an Ultraviolet (UV) light sensor for determining a value of Ultraviolet B (UVB) radiation during exposure of sunlight on a body of a user; and
a microcontroller for:
determining an exposure time of the user to the sunlight;
determining an UVB dosage of the user based on a reciprocal of a product of the exposure time and a predefined weightage factor, wherein the predefined weightage factor is associated with a wavelength of the UVB radiation; and
determining an amount of Vitamin D produced in the body of the user based on the UVB dosage of the user.
