Abstract

Context: A lot of folks use social networking sites every day. Adults now often browse social networking sites thanks to the rise in smartphone use. Their cognition and sleep cycles may be impacted by this habit. The purpose of this study was to ascertain how internet addiction affected both sleep quality and cognition. To ascertain how internet use affects the quality of sleep. To examine the relationship between adult internet addiction and cognition. Environment and Design: Cross-sectional prospective study was the study's design. 1. Study location: Karpaga Vinayaga Institute of Medical Sciences and Research Center, Department of Physiology. 2. One month of study. 3. Study population: adults between the ages of 18 and 22. 4. 100-sample minimum (Sample size = P(1-P)/d2/Z1-a/22/Z1-a/22). 5. Simple random sampling is the sample design. Materials and Methods: Preliminary data will be gathered after receiving ethical approval and informed consent. The Montreal Cognitive Assessment (MOCA) Questionnaire, the Pittsburgh Sleep Quality Index (PSQI), and the Internet Addiction Test (IAT) were used to collect the data. Inclusion standards: 18 to 22-year-old age range. Major mental and neurological conditions; individuals with head injuries; exclusion criteria. Utilizing statistical analysis all data was entered into an MS Excel data sheet, and after the study is over, SPSS software version 17.0 will be used to statistically analyse the data. The average, standard deviation, and percentage of the data were displayed. Results: It has been demonstrated through our study that adults are increasingly using smartphones to visit social networking sites. Their cognitive and sleep patterns are both impacted by this behaviour. Therefore, it is crucial to spread the crucial knowledge among students in order to encourage the proper internet usage pattern and lessen students' sleep issues. Key Message : In order to prevent sleep issues, we must raise awareness among students about the need of using the internet in the right way. Keywords: Montreal cognitive assessment, Pittsburgh sleep quality index, Internet Addiction Test (MOCA).

Abstract

Introduction: Medical students are exposed to various stresses, which is known to affect cardiovascular system which can be assessed by noting the heart rate variability (HRV). Aims: To assess the anxiety, stress and HRV in first year medical students and study the effect of one month integrated yoga intervention on them. Materials and Methods: Spielberger state-trait anxiety inventory (STAI) and Perceived stress scale (PSS) were administered to 150 first year medical students. 60 students with a high anxiety and stress score were selected on the basis of specific inclusion and exclusion criteria and divided into study and control groups. A baseline HRV was documented on all 60 students. 30 students in the study group underwent supervised yoga intervention for one month. Post interventional assessments of anxiety, stress and HRV were done in both groups (study and control group). Paired t test was used to determine the statistical difference in pre and post interventions and independent t test was used to determine the statistical difference between control and study groups. Results: There was significant decrease in anxiety state and perceived stress with yoga intervention. Heart rate variability revealed that SDNN, RMSSD, Mean HR were significantly higher and  LF, LF/HF ratio were significantly reduced after one month practice of yoga showing a shift towards parasympathetic dominance. Conclusions: Integrated yoga intervention showed significantly decreases in state anxiety and perceived stress, and a shift towards parasympathetic dominance in heart rate variability. However, the anxiety trait didn’t show significant improvement.
