Effects of natural fibres (cotton, linen, silk) on the quality of sleep. The aim of this study was to evaluate the possible influence of sleeping in cotton, linen or silk sheets, on the quality of sleep. Five subjects were studied, 3 females and 2 males between the ages of 25 and 32 (average age, 29.6), of medium-high sociocultural status, in good health and without problems either of getting to sleep or sleeping. The instruments used were: biofeedback for the observation of the skin psyconeurophysiological profile; Osgood's Semantic differential adapted to our study protocol. The procedure consisted in the use of the instruments as mentioned above, during the months of October, February and July, after the subjects had slept for nights in cotton, linen and silk sheets respectively. The subjects were given the questionnaires on sleep and subsequently underwent, without clothes and wrapped up respectively in cotton, linen and silk sheets, the measurement of psyconeurophysiological parameters through biofeedback. The results of the preliminary research on the effects of natural fibres (cotton-linen-silk) on the quality of sleep show that there are seasonal differences (autumn- winter-summer) that make it possible to identify some preference for the various fibres in the different seasons. One can observe that in autumn cotton is the most preferred fibre, which obtains the lowest value at EMG, at T it is the most personally preferred; in winter linen obtains the lowest EMG value, at T it is the most subjectively favoured; in summer at equal subjective preference, linen is characterised by its low values at GSR and at T, silk by its low values at EMG and GSR.
