tDCS for Stress and Burnout in Higher Education

The goal of this clinical trial is to evaluate if transcranial direct current stimulation (tDCS) works to reduce occupational stress and burnout in university professors. The main questions it aims to answer are: Does tDCS reduce levels of occupational stress in university professors? Does tDCS reduce burnout levels in university professors? Researchers will compare active tDCS to a sham stimulation (a look-alike procedure that contains no active stimulation) and a control group to see if tDCS effectively reduces stress and burnout. Participants will: * Complete questionnaires assessing stress and burnout levels before the intervention * Complete follow-up assessments immediately after the intervention and 5 weeks later During intervention, participans of active tDCS and Sham gruops will: * Receive 10 sessions of tDCS over 4 weeks (excluding weekends), 20 minutes each
