1. A method of assessing sleep quality of a user in a sleep session, the method comprising:
by way of a plurality of sensors, obtaining sleep session data comprising a plurality of physiological parameters of the user indicative of the user's sleep quality during a first sleep session, the plurality of physiological parameters including a heart rate parameter and a motion parameter;
by way of a processor, calculating a first sleep quality index based on at least the heart rate parameter, the motion parameter, and a sleep duration value;
after the first sleep session, receiving user data input by the user into a user interface;
by way of the processor, adjusting the sleep duration value to a new sleep duration value based on the received user data;
by way of a processor, calculating a new sleep quality index based on the new sleep duration value;
communicating the new sleep quality index to at least the user for displaying the new sleep quality index on a display; and
communicating feedback to the user by controlling display of information on the display to the user regarding improvements for future sleep sessions determined based on the new sleep quality index.
