A readaptation effect to the sleep laboratory was demonstrated for insomniac subjects who returned lo the laboratory for a second series of consecutive nights after spending one week at home. This effect was similar to that seen in the initial adaptation period, i.e. REM percentage, REM min. number of REM periods, min stage 4. and percentage stage 4 were decreased on the first night upon returning to the laboratory as compared to subsequent nights. In addition, there was an increase in percentage stage 2, sleep latency, and total wake time on this first laboratory night.
