摘要

隨著資訊科技的進步，電腦與網路快速的發展，許多人在現實社會中無法獲得滿足感，因而轉向虛擬的網路世界中，藉此獲得滿足感，或是在網路中建立自信，許多人因此沉迷上網，長時間的上網、對生理及心理造成負面的影響，例如：肩頸痠痛、眼睛紅腫、疲勞、睡眠品質不佳、失眠、脾氣暴躁、沒有耐心、注意力不集中，嚴重的話可能會導致猝死（過勞死）。本研究的目的是探討網路遨遊時電腦工作者上午及下午生理效應關聯之研究。研究結果顯示：（1）受測者在上午及下午上網後HR有顯著差異，下午心跳比早上快，因為早上血壓慢慢上升，直到下午血壓值到達最高，而血壓上升時心跳也會加快。（2）副交感神經活性（HF%），交感神經活性，（LF%），交感副交感平衡性指標（LF/HF）有顯著差異，早上由於交感神經作用，因此LF的值明顯較高，此時人們比較有精神及專注力，下午副交感神經活性（HF）的值比較高，因此人們感覺到比較鬆懈或是疲勞。因此早上比較適合做需要腦力思考的事情，如果是上網或是比較不需要思考的事情，適合在下午做。

With the progression of information technology, a greater number of people use the Internet at work. Previous studies focused on the effects of shyness, anxiety, loneliness, depression, and self-consciousness on the level of Internet use. This study examines the physiological effects of Internet surfing on workers. Participants consisted of 20 university and graduate students. Each participant was measured 4 times in the morning and in the afternoon. Heart rate variability (HRV), blood pressure, and pulse rate were measured as physiological indices. Results showed that (1) Internet surfing in the morning and afternoon caused significant differences in the participants' heart rate (HR). In the afternoon, heartbeats were faster than in the morning. (2) As HF%, LF%, and LF/HF are significantly different, the value of HF is higher in the afternoon, which causes people to feel more relaxed or fatigued. Therefore, activities that require more thinking should be performed in the morning, and activities that require less thinking should be performed in the afternoon.
