Resting parameters were recorded before the start of each experiment after subjects had rested for
minimum 30 minutes. These were heart rate, respiration frequency and grip strength. The subjects were told
to write down continuously (like taking an examination) for 30 minutes; a given preset text. The parameters
were recorded again while at work. Peak heart rate reading was taken with the help of Polar Heart Rate
Monitor. Immediately upon completing the task, Grip Dynamometer and Expirograph were used
simultaneously to record respiration frequency and grip strength. At the end of the experiment, subjective
responses were also taken on score sheet. Each experiment was repeated thrice on each subject
