Objective: The mechanisms behind building-related symptoms have remained unknown despite many years of research. It is known that environmental and psychosocial factors are of importance. Some receptors in the Transient Receptor Potential family elicit the same symptoms when stimulated, as reported by those suffering from building-related symptoms. The aim of this study was to compare capsaicin sensitivity between people with and without skin symptoms. A second aim was to investigate perceived stress among individuals with different levels of capsaicin sensitivity.
Methods: People referred to an occupational health care unit and judged to have building-related symptoms by a physician answered a questionnaire regarding their symptoms. Solutions with different capsaicin concentrations were applied to participants' nasolabial folds. Self-reported stress and burnout were assessed using two questionnaires: the Perceived Stress Scale (PSS) and the Shirom-Melamed Burnout Questionnaire (SMBQ).
Results: We found that people who reported facial erythema or itching, stinging, tight or burning facial skin were more sensitive than those without symptoms and similarities with Sensitive Skin are discussed. We also found that participants who reacted to the lowest capsaicin concentrations scored significantly higher on scales for stress and burnout.
Conclusions: We found associations between sensitivity to capsaicin and skin symptoms among people with building-related symptoms, as well as associations between capsaicin sensitivity and perceived stress/burnout.
