Stress and Hidradenitis Suppurativa: What Research Shows About HS Flares

Hidradenitis suppurativa, often shortened to HS, is a chronic inflammatory skin disease that causes painful lumps, abscesses, and sometimes tunnels under the skin, usually in areas where skin rubs together, such as the armpits, groin, and under the breasts. It is often misdiagnosed for years as recurring boils or poor hygiene, which it is not. Many people living with HS say that stressful periods seem to bring on flares, and online wellness content sometimes blames the whole condition on "high cortisol." The research supports a real connection, but a more limited one.

HS is best understood as an immune-driven disease. Clinical reviews describe it as starting with blockage and inflammation around hair follicles, followed by an overactive immune response that drives swelling, pain, and drainage. Genetics, smoking, excess weight, and hormonal factors are all associated with higher risk or more severe disease. According to the American Academy of Dermatology, quitting smoking and gentle skin care, such as antimicrobial washes and avoiding scrubbing, may help reduce flare-ups. Stress is not considered a cause of HS, but it is one of the triggers patients most often report.

Why might stress matter? Psychological stress is known to influence the immune system through stress hormones and nerve signals in the skin, and it is associated with flares of several inflammatory skin conditions, including psoriasis and eczema. A recent review proposing a neuroendocrine-immune model of HS argued that purely skin-focused explanations do not fully account for stress-related and menstrual flares, and that pathways linking the brain, hormones, and immune cells likely play a role. That is a promising framework, but the authors also note that much of it is still being worked out, and there are few studies directly tracking stress, cortisol, and HS flares over time.

The connection also runs the other way. HS can be painful, visible, and socially isolating, and it often affects intimate areas of the body. A 2019 systematic review and meta-analysis in JAMA Dermatology by Machado and colleagues, covering more than 40,000 adults with HS, found that about 17 percent had depression and that people with HS had significantly higher odds of depression than people without it. Anxiety was also common. Because stress, mood, pain, and disease activity can feed into one another, researchers caution that it is hard to tell how much stress drives flares versus how much flares drive stress.

What does this mean for treatment? Medical therapy remains the foundation. Depending on severity, dermatologists may use topical or oral antibiotics, hormonal treatments, biologic medications that target specific immune signals, and procedures to treat tunnels and scarring. Stress management, such as good sleep, regular movement, therapy, or mindfulness, may help people cope and could plausibly reduce some flares, and Cleveland Clinic and other clinical sources recommend it as part of an overall plan. It works best as a complement to medical care, not a replacement.

So what is proven and what is trend? Well supported: HS is a chronic inflammatory disease, and people with HS face a higher burden of depression and anxiety. Plausible but still being studied: that stress triggers flares through immune and hormonal pathways. Trend and marketing: claims that a "cortisol-lowering" supplement, detox, or diet will cure HS. If you have recurring painful lumps in skin folds, a dermatologist can confirm the diagnosis, and earlier treatment is generally associated with better outcomes.
