According to a recent study published in the Journal of the American Academy of Dermatology, hyperhidrosis appears to be associated with severe sleep disturbances, high stress, and self-reported depression.
This brief letter suggests that adults with primary hyperhidrosis are more likely to report sleep disturbances, daytime tiredness, stress, and depressive symptoms than those without hyperhidrosis.
The authors leveraged data from the Danish Blood Donor Study, which has the advantages of a community-based (in contrast to a patient) population and—as the authors' highlight—screening out many potential causes of secondary hyperhidrosis. Some of the other strengths of this study include using validated measures for sleep and psychological variables, the high response rate among donors, and the robust analytic techniques (many of which are spelt out in the supplemental material). Regression analyses were controlled for sex, age, smoking, body-mass index, and season. Some limitations include the inability to infer causality because of the cross-sectional design and the lack of data regarding hyperhidrosis severity about sleep and psychological variables. In addition, the report does not specify the specificity and sensitivity of the screening question ("Do you have troublesome sweating?") for an actual diagnosis of hyperhidrosis.
Among the 9% of adults with presumed hyperhidrosis, moderate and severe stress rates were nearly twofold and threefold higher, respectively, compared with control adults. Hyperhidrosis was also associated with higher rates of several sleep-disturbance items and depression.
Overall, this study is well-conducted and sets the groundwork for subsequent studies that may, for instance, examine the clinical course of hyperhidrosis about psychological measures and whether hyperhidrosis treatment leads to the resolution of psychological distress and disorders.
