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.

Objective: To study whether the duration of exposure to noise significantly affects hearing threshold level in bus drivers.
Materials and method: Study was conducted on 30 male drivers working in Bangalore Metropolitan Transport Corporation (BMTC), Bangalore, between the age group 20 - 50 years and pure tone audiometric evaluation was done.
Results: Drivers with more no. of years of job experience had high levels of hearing threshold (p<0.001) both for lower and higher frequencies but significantly more for higher frequency. This study shows that hearing loss is found in drivers at an earlier age since majority were between 30-40 years.
Conclusion: The risk of hearing loss and injury to ears increase with the sound intensity, duration of exposure to noise and individual susceptibility. Awareness has to be created in drivers by implementing education and training programs has to be conducted about the hearing protectors.
