Zusammenfassung:	The effect of fatigue treatment on the thermal conductivity of wood was studied. Fresh Norway spruce samples both with and without fatigue were analyzed in a temperature rise experiment by means of an infrared camera. The experimental temperature profiles were compared to finite-element simulations of heat conduction. The temporal features of temperature profiles indicate an increase in the conductivity of fatigued wood, which points to changes in the cellular structure of wood. The importance of fatigue for thermal conductivity and consequently for mechanical pulp-making is discussed.
