Processor for processing skin conductance data of a living being, the processor comprising: - an input unit for receiving a skin conductance data signal comprising a plurality of data peaks; - a calculating unit for computing a skin conductance peak data signal over a period of at least one day by deriving a feature related to said data peaks from said skin conductance data signal and forming a summation of said feature per time unit; and - an analyzing unit for analyzing an average and/or an absolute value of said skin conductance peak data signal over at least a portion of said period to get information on at least one stage of burnout and/or chronic fatigue syndrome of said living being, characterized in that : said analyzing unit is configured to compare the average and/or absolute value of said skin conductance peak data signal against two different thresholds, and - an output unit configured to output • a full stage signal indicating a full stage of said predetermined stress state when the average and/or absolute value of said skin conductance peak data signal falls below a lower threshold after it has exceeded said upper threshold , and • a recovery stage signal indicating a recovery stage when the average and/or absolute value of said skin conductance peak data signal rises towards and/or exceeds said lower threshold without exceeding said upper threshold after said full stage of said predetermined stress state, and • a healthy state signal, when the average and/or absolute value of said skin conductance peak data signal is above said lower threshold and below said upper threshold . - an input unit for receiving a skin conductance data signal comprising a plurality of data peaks; - a calculating unit for computing a skin conductance peak data signal over a period of at least one day by deriving a feature related to said data peaks from said skin conductance data signal and forming a summation of said feature per time unit; and - an analyzing unit for analyzing an average and/or an absolute value of said skin conductance peak data signal over at least a portion of said period to get information on at least one stage of burnout and/or chronic fatigue syndrome of said living being, characterized in that : said analyzing unit is configured to compare the average and/or absolute value of said skin conductance peak data signal against two different thresholds, and - an output unit configured to output • a full stage signal indicating a full stage of said predetermined stress state when the average and/or absolute value of said skin conductance peak data signal falls below a lower threshold after it has exceeded said upper threshold , and • a recovery stage signal indicating a recovery stage when the average and/or absolute value of said skin conductance peak data signal rises towards and/or exceeds said lower threshold without exceeding said upper threshold after said full stage of said predetermined stress state, and • a healthy state signal, when the average and/or absolute value of said skin conductance peak data signal is above said lower threshold and below said upper threshold . • a full stage signal indicating a full stage of said predetermined stress state when the average and/or absolute value of said skin conductance peak data signal falls below a lower threshold after it has exceeded said upper threshold , and • a recovery stage signal indicating a recovery stage when the average and/or absolute value of said skin conductance peak data signal rises towards and/or exceeds said lower threshold without exceeding said upper threshold after said full stage of said predetermined stress state, and • a healthy state signal, when the average and/or absolute value of said skin conductance peak data signal is above said lower threshold and below said upper threshold . <EOS>
