To summarise, research suggests boredom is distinct from depression. In tests, [3]people seemed to recover from depression much faster than they did from boredom. [4]Boredom is associated with rising HR, decreased SCL, and increased cortisol levels. [5]Those symptoms are possibly triggers for or present in people suffering from depression. People expressing high level of boredom may suffer from substance abuse, relationships and career building like with depression. Noting everything, it seems quite plausible boredom can be a trigger for depression and vice versa. Literally everything that causes boredom can also cause depression and the symptoms from both are trigger for each other despite being different enough. 0] Relationships between boredom proneness, mindfulness, anxiety, depression, and substance use: http://www.azmonyar.com/DownloadPDF/15562289.pdf http://www.azmonyar.com/DownloadPDF/15562289.pdf 1] Proneness to boredom mediates relationships between problematic smartphone use with depression and anxiety severity: https://journals.sagepub.com/doi/abs/10.1177/0894439317741087 https://journals.sagepub.com/doi/abs/10.1177/089443931774108... 2] Traumatic brain injury, boredom and depression: https://www.mdpi.com/2076-328X/3/3/434 https://www.mdpi.com/2076-328X/3/3/434 3] An open label pilot study of citalopram for depression and boredom in ambulatory cancer patients: https://www.cambridge.org/core/journals/palliative-and-supportive-care/article/an-open-label-pilot-study-of-citalopram-for-depression-and-boredom-in-ambulatory-cancer-patients/3EB20E1D6871E64B2C252CE8D99C166E https://www.cambridge.org/core/journals/palliative-and-suppo... 4] Characterizing the psychophysiological signature of boredom: https://link.springer.com/article/10.1007/s00221-013-3755-2 https://link.springer.com/article/10.1007/s00221-013-3755-2 5] Cortisol Secretion in Depressed and At-Risk Adults: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4451064/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4451064/
