Data were collected from August 26 to September 17, 2010, using a cyber leisure questionnaire and heart rate variability (SA-6000, Medicore, Korea) for autonomic function. Results: Total time for the cyber leisure activity was 391.3± 262.0 (min/week). Time for internet usage and computer game was 234.5±140.1 (min/week) and 156.8±164.3 (min/week), respectively. There were significant positive correlation between total cyber leisure time and sympathetic activity (r=.247, p<.001).
