A person's sleep disorders are resolved by applying low frequency vibration. Mechanical vibrators ( 1 ) present on a first side of a plate type base member ( 9 ) set the plate type base member ( 9 ) in vibration in such a way that its second surface transmits mechanical vibration. A plurality of first low frequency pulse trains ( 100; 101, 102, 103 . . . ) of mechanical vibration are conducted to a part of the person's body, at successive time periods (T; T 1 , T 2 , T 3 . . . ). A frequency (f) of vibration in each individual pulse train ( 100 ) is maintained constant (f; fa, fb, fc . . . ) within the range of 20-50 Hz. The pressure pulses ( 400 ) of said pulse train ( 100 ) have a contact power (I) with said part of the body within the range of 40-70 dB. The constant frequencies (fa, fb, fc . . . ) of the successive pulse trains ( 100; 101, 102, 103 . . . ) are mutually different and change monotonously and mostly linearly. At least one second pulse train ( 100 ) is transmitted to said part of the body. |
