Summary

This clinical trial aims to determine if Transcranial electrical stimulation by direct current (tDCS) and transauricular Vagus Nerve Stimulation (tVNS) treatments are effective in reducing stress symptoms, distress and improving sleep quality in adults. The main questions it aims to answer are:

* Determine if tDCS effectively reduces the intensity of stress symptoms in adults.
* Determine if tDCS is effective in reducing levels of distress in adults.
* Determine if tDCS is effective in improving sleep quality.
* Determine if tVNS is effective in reducing the intensity of stress symptoms in adults.
* Determine if tVNS is effective in reducing levels of distress in adults.
* Determine if tVNS is effective in improving sleep quality.

Conditions

  • Stress
  • Sleep

Interventions

DEVICE

tDCS

For true tDCS, the technique will be performed with the anode over the right dorsolateral prefrontal cortex and the cathode over the left dorsolateral prefrontal cortex, positioned at F4 and F3, respectively, according to the International 10/20 Electrode Placement System. The current intensity will be set to 2 milliamperes (mA) for 20 minutes over five consecutive days.

DEVICE

tVNS

For true tVNS stimulation, the technique will be performed with the electrodes positioned on the upper concha of the left ear, using gel for better current distribution.
