Abstract:
Nine young girls participated in cross-over sessions, sleeping with either multi-functional fabric (experimental session) or cotton (control session). The relative duration of slow-wave sleep (SWS) was 1.89-fold higher in the experimental session than in the control session. The peak growth hormone (GH) secretion in the experimental session was more than 2.4-fold higher than during the control session (p <.001). The quality of sleep during the experimental session was significantly better than in the control session (p <.01). These results suggest that multi-functional fabric wear is effective in inducing deep sleep, increasing GH, and improving the quality of sleep.
