9. The method of claim 1 , wherein the transitioning gradually adjusts the first target glucose setpoint value to the second target glucose setpoint value over a predetermined period of time.

10. The method of claim 1 , further comprising:

monitoring a sleep duration of the user; and

initiating the transitioning when the sleep duration exceeds a threshold time period.

11. An insulin infusion device comprising:

a fluid pump mechanism;

at least one controller that regulates operation of the fluid pump mechanism to deliver insulin from the insulin infusion device; and

at least one memory element associated with the at least one controller, the at least one memory element storing processor-executable instructions configurable to be executed by the at least one controller to perform a method of controlling operation of the insulin infusion device, the method comprising:

operating the insulin infusion device in an automatic mode to automatically control delivery of insulin to a user, in accordance with a first target glucose setpoint value;

receiving user status data that indicates sleeping status of the user, the user status data being sensor data generated by a sleep detection system;

determining, from the user status data, that the user is sleeping while the insulin infusion device is operating in the automatic mode;

in response to the determining, transitioning from the first target glucose setpoint value to a second target glucose setpoint value for use during the automatic mode, the transitioning occurring without user input, and the second target glucose setpoint value being different from the first target glucose setpoint value; and

continuing to operate the insulin infusion device in the automatic mode to automatically control delivery of insulin to the user, in accordance with the second target glucose setpoint value.

12. The insulin infusion device of claim 11 , wherein the insulin infusion device receives the user status data directly from the sleep detection system.

13. The insulin infusion device of claim 11 , wherein the method performed by the at least one controller further comprises:

receiving additional user status data that indicates sleeping status of the user, the additional user status data generated by the sleep detection system;

determining, from the additional user status data, that the user is awake;

in response to determining that the user is awake, transitioning from the second target glucose setpoint value to the first target glucose setpoint value without user input; and

continuing to operate the insulin infusion device in the automatic mode to automatically control delivery of insulin to the user, in accordance with the first target glucose setpoint value.

14. The insulin infusion device of claim 11 , wherein:

the user status data includes a sleep quality metric for the user, the sleep quality metric generated by the sleep detection system; and

the transitioning adjusts the first target glucose setpoint value as a function of the sleep quality metric to obtain the second target glucose setpoint value.

15. The insulin infusion device of claim 11 , wherein:

the user status data includes a sleep duration metric for the user, the sleep duration metric generated by the sleep detection system; and

the transitioning adjusts the first target glucose setpoint value as a function of the sleep duration metric to obtain the second target glucose setpoint value.

16. The insulin infusion device of claim 11 , wherein the transitioning gradually adjusts the first target glucose setpoint value to the second target glucose setpoint value over a predetermined period of time.

17. The insulin infusion device of claim 11 , wherein the method performed by the at least one controller further comprises:

monitoring a sleep duration of the user; and

initiating the transitioning when the sleep duration exceeds a threshold time period.

18. A system comprising:
