A sleep system including a thermal pad and a thermal control unit in thermal communication with the thermal pad. The thermal controller is configured to automatically adjusts a temperature of the thermal pad during a sleep cycle time according a programmed routine. During the preprogrammed routine, the thermal control unit maintains the temperature in the thermal pad at a first temperature T 1. After a first time period S 1 from the initiation of the sleep cycle, the thermal control unit adjusts the temperature in the thermal pad a ΔT, for example to a second temperature T 2. The second temperature T 2 is dependent of the first, preset, temperature T 1 and the ΔT. The thermal pad temperature is maintained at the second temperature T 2 for a majority of the sleep cycle. At a time period S 2 before the end of the sleep cycle, the temperature in the thermal pad 12 adjusted a ΔT to a third temperature T 3. |
