The invention relates to a method for resolving a person's sleep disorders by applying low frequency vibration to a part of the body, said method comprising the use of mechanical vibrators (1) present on a first side of a plate type base member (9) for setting the plate type base member (9) in vibration in such a way that is second surface transmits mechanical vibration, comprising a plurality of low frequency pulse trains (100) which are conducted to a part of the person's body. The successive pulse trains of mechanical vibration to be transmitted in the invention to a specific part of the body comprise both—a plurality of first successive pulse trains (100； 101, 102, 103 . . . ) transmitted at successive time periods (T； T1, T2, T3 . . . ) to said part of the body, wherein a frequency (f) of vibration in each individual pulse train (100) is maintained constant (f； fa, fb, fc . . . ) over the course of a duration (T； T1, T2, T3 . . . ) of said pulse train (100), said constant frequency being within the range of 20-50 Hz and the vibration at the same time being such that 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, whereby the constant frequencies (fa, fb, fc . . . ) of the successive pulse trains (100； 101, 102, 103 . . . ) to be transmitted to the part of the body at the successive time periods (T； T1, T2, T3 . . . ) are mutually different and change monotonously and mostly linearly, and—at least one second pulse train (100) transmitted to said part of the body, wherein pressure pulses (400) contained in the pulse train (100) have a frequency (f) fluctuating within the range of 20-50 Hz, preferably within the range of 20-40 Hz, over the course of 2-10 seconds, preferably over the course of 5-7 seconds, and said frequency changes in accordance with sine, triangle or square wave, preferably in accordance with sine wave.
