Why South Florida's Summer Heat Makes Hidradenitis Suppurativa Flare Up More Often

If you live with hidradenitis suppurativa, you may have already noticed a pattern: as temperatures climb and the humidity builds across South Florida, your skin gets angrier. More nodules, more tenderness, more drainage. And right now, heading into late spring and summer, that pattern is about to become very familiar again.

You are not imagining it. The heat, sweat, and friction that come with South Florida's climate are genuine triggers for HS flare-ups. Understanding why can help you take more control of your condition before the worst of the season hits.

What Is Hidradenitis Suppurativa?

Hidradenitis suppurativa, often called HS, is a chronic inflammatory skin condition that affects the hair follicles in areas where skin rubs together. It causes painful, deep lumps, abscesses, and tunneling wounds that can recur over time.

Common locations include:

• The underarms
• Groin and inner thighs
• Under the breasts
• Buttocks and perianal area

HS is not contagious and is not caused by poor hygiene. It is a complex immune-mediated condition that tends to be underdiagnosed and undertreated. Many patients spend years managing symptoms without ever receiving a formal diagnosis or a clear treatment plan.

Why Summer in South Florida Makes HS Worse

South Florida's climate during spring and summer is among the most intense in the country. High temperatures, extreme humidity, and heavy outdoor activity create a combination that directly aggravates the skin conditions that drive HS flares.

Here is what is happening:

• Sweat increases friction. When skin-to-skin contact zones stay moist from sweat, the mechanical irritation at hair follicles increases significantly. This is one of the most well-recognized HS triggers.
• Heat expands sweat glands. Elevated body temperature causes sweat glands and pores to work harder. In HS-prone areas, this can contribute to follicular occlusion, the process believed to initiate many flares.
• Clothing becomes a problem. Summer fabrics that stick to damp skin, tight waistbands, athletic wear, and swimsuit edges can all create repeated friction against already-sensitive areas.
• Inflammation is easier to trigger. Heat itself can promote a mild pro-inflammatory state in the skin, lowering the threshold for a flare in people with HS.
• Dehydration and diet shifts matter. Summer changes in eating patterns, increased alcohol intake at social events, and dehydration from being outdoors can all influence systemic inflammation.

South Florida residents face this challenge from roughly April through October, which means HS management here is not just a winter break. It is a sustained, season-long effort. This is similar to the patterns seen with other inflammatory skin conditions in our region, like eczema flare-ups driven by heat and humidity and rosacea worsened by sun and high temperatures.

Practical Steps to Reduce HS Flares This Summer

While HS requires medical management, there are daily habits that may help reduce flare frequency and severity during the warmer months:

• Choose loose, breathable clothing. Natural fibers like cotton and moisture-wicking fabrics reduce friction and allow sweat to evaporate. Avoid tight waistbands and seams that press directly on affected areas.
• Shower promptly after sweating. Rinsing off sweat and bacteria from the skin surface can reduce irritation in HS-prone zones. Use a gentle, fragrance-free cleanser.
• Apply zinc-based powders or barrier creams. In high-friction areas, these products may help reduce the mechanical irritation that contributes to flares. Ask your dermatologist which products are appropriate for your skin.
• Manage your weight if applicable. Excess skin folds increase friction and heat retention in HS areas. Even modest weight changes can influence flare frequency for some patients.
• Avoid shaving affected areas. Shaving in active HS zones can worsen inflammation and introduce bacteria. Discuss alternative hair removal methods with your dermatologist.
• Watch for known dietary triggers. Some patients find that dairy, refined sugars, or certain foods seem to correlate with flares. Keeping a symptom journal over the summer can help identify patterns.
• Stay hydrated. Consistent hydration supports overall skin barrier function and may help manage systemic inflammation.

When to See a Dermatologist for Hidradenitis Suppurativa

Many people with HS have never seen a dermatologist specifically for the condition. Some have been told it is recurring boils or infection and treated with antibiotics alone. If your symptoms are coming back season after season, a dermatologist evaluation can make a real difference.

Signs that it is time to schedule an appointment include:

• Painful lumps that keep returning in the same areas
• Abscesses that drain and leave scarring
• Tunneling or connected wounds under the skin
• Flares that are getting more frequent or severe
• Symptoms that are affecting your daily life, sleep, or mental health

HS treatment has expanded significantly in recent years. Depending on the severity of your condition, management options may include prescription topicals, oral medications, biologics approved specifically for HS, and procedures performed in-office to address tunnels or chronic lesions. No single approach works for everyone, which is why a board-certified dermatologist's evaluation is so important.
