Effect of Stress on Sleep in it Individuals of Bangalore City
Subscribe/Renew Journal
The urban lifestyle aggravated by rat racing is a stressor, taking toll on the elixir of life, the sleep. In addition IT professionals are always under high work pressure, more achievement oriented and their long working hours lead to high stress. Hence the current study is undertaken to investigate the effect of stress on sleep architecture in IT professionals.
Objectives: To Evaluate the sleep architecture by using polysomnography in subjects having high stress score.
Methodology: The IT professionals of Bangalore city in the age group of 25-40 years were given State Trait Anxiety Inventory questionnaire. 44 subjects who scored above 40 in STAI were considered stressed and subjected to polysomnography recording in the sleep lab at Victoria hospital, BMCRI. The recording was scored manually by Kales method and statistically analysed
Results: It was found that PSG parameters like sleep latency, wake after sleep onset, stage1% were prolonged and sleep efficiency reduced in the study group as compared to normative data for that age group given by American Academy of Sleep Medicine manual.
Interpretation&Conclusions: The increased activity in Locus-ceruleus and nor-epinephrine projections as well as increased levels of ephinephrine and cortisol during stress are responsible for the altered parameters on PSG.
