A temperature regulating pad has an air-permeable top layer, a perforated middle layer, and a bottom layer. The perforated middle layer is located between the top layer and the bottom layer. The top layer and the perforated middle layer delimit an upper airspace and the perforated middle layer and the bottom layer delimit a lower airspace. A slot is disposed through the pad to create a flap that can fold over onto the top of the patient. Forced air is received into the lower airspace and flows from the lower airspace into the upper airspace through the perforated middle layer, exiting the air-permeable top layer into an external airspace surrounding the patient. With the patient resting on the pad and the foldable flap deployed, warm air flows directly from underneath and above to regulate the temperature of the patient.
