•Participants must be aged 18\-65 years and score higher than 62 on the Penn State Worry Questionnaire (PSWQ), a questionnaire designed to assess worry as a behavioural trait. As described by Behar et al (2003\), a cut\-off score of 62 on the PSWQ will allow for a highly sensitive and selective selection of chronic worriers when assessing an advertised\-for population.
•Participants can only participate in this study if they have a smartphone on which they can download the app which will be used to prompt participants to answer the daily questions.

•Exclusion criteria for this study are based on the study by Kreuzer and colleagues (2012\). As such, participants will be excluded from participating in the proposed study if they are diagnosed with a neurological or cardiac disease, and if the participant does not have a history of alcohol or drug abuse. Participants will be excluded from participating in this study if they use other psychological or pharmacological interventions at the start of or during the study.
•Additionally, participants will be excluded if they can\*t read and comprehend Dutch language, and if they are unable to give informed consent.
•Finally, participants are excluded from participating in this study if they indicate that the stimulation is intolerable.
