The present invention relates to an infrared radiation device including a mounting (2) capable of receiving a user (9) and a covering portion (1) capable of covering the user (9), the covering portion (1) including at least one heating layer (5a, 5b, 5c) capable of emitting infrared radiation (6) in a predetermined range of wavelengths towards at least one portion of the space located between the inner surface of the beating layer (5a, 5b, 5c) and the mounting (2), the device being characterised in that said heating layer (5a, 5h, 5c) is adjusted by at least one controller (10) including power-supply means (16) supplying the power necessary for infrared emission and at least one programmer (15) determining the parameters of a radiation session, by defining pulsations that control at least one synchronous static relay (14) which supplies said heating layer (5a, 5b, 5c) with the power provided by the power-supply means (16) during the pulsations.
