1. A system with features to estimate core temperature of a sleeper of a bed, the system comprising:
the bed having a mattress having a mattress cover;
one or more temperature sensors positioned under the mattress cover, each sensor configured to:
sense a temperature for the sleeper on the mattress; and
transmit, to a controller, temperature readings;
one or more pressure sensors, each pressure sensor configured to:
sense a pressure applied to the mattress by the sleeper; and
transmit, to the controller, pressure readings;
the controller comprising a processor and memory, the controller configured to:
receive, from the one or more temperature sensors, the temperature readings;
determine a skin temperature for the sleeper based on the temperature readings from the one or more temperature sensors positioned under the mattress cover;
receive, from the one or more pressure sensors, the pressure readings;
determine at least one cardiac parameter for the sleeper using the pressure readings; and
determine, from the skin temperature and the at least one cardiac parameter, the core temperature for the sleeper that is different than the skin temperature and represents a thermal state of a core of a body of the sleeper using a first core-determining function selected from a plurality of possible core-determining functions based on the first core-determining function being associated with a subpopulation to which the sleeper belongs.
