The present invention relates to an infrared radiation device including a mounting (2) capable of receiving a user who is lying down (9) and a covering portion (1) capable of covering the user (9) who is lying down on the mounting (2). The covering portion (1) includes a first heating layer (5a) which is capable of emitting infrared radiation (6) in the space located between the inner surface of the first heating layer (5a) and the mounting (2). The profile of the first heating layer (5a) is a parabolic curve allowing improved distribution of the infrared radiation (6).
