Epitympanic temperature (Tty) at room temperature (a; 23.2 ± 0.4 °C) and low temperature (b; −18.7 ± 1.0 °C) in relation to exposure time in minutes. Data are displayed for group A (solid lines; exposure to low followed by room temperature), group B (dotted lines; exposure to room followed by low temperature), with insulation of the ear (black) and without insulation of the ear (grey)
