Information and Communication Technology (ICT) has been constituted as a pivotal role in our society. Newer computers and TV screens are now frequently equipped with light-emitting diodes (LED), which peak in the short-wavelength region and which are primarily responsible for a variety of nonvisual light responses, in particular, resetting the timing of the circadian pacemaker, suppressing melatonin production, improving alertness and performance, and elevating brain activation, as assessed from EEG-derived correlates of arousal. Physical Exercise is recommended by the American Sleep Disorders Association as a non-pharmacological intervention to improve sleep. Hence we examined whether exercise may help to improve the sleep quality among IT professionals.
1. To find the interrelationship between hours of computer exposure, exercise and sleep quality in information technology professionals of Bangalore.
This study includes 40 IT professionls. The practice of physical activities, use of computers during weekdays and participants’ demographic information such as gender and age were collected. Quality and quantity of sleep was evaluated by Pittsburgh Sleep Quality Index (PSQI) questionnaire.
Mean age was 25.9±2.2 yrs, computer exposure 8.45±2.3 hrs and mean PSQI score is 5.02±1.8 and is indicative of poor quality of sleep. There was significant positive association between computer exposure and PSQI and negative association between exercise and PSQI.
The results of the present study indicate a negative association between level of physical activity and computer exposure among IT professionlas of Bangalore.
