If you live with Hidradenitis Suppurativa (HS), you’ve probably tried a lot of things just to get through the day. Some help a little, some not at all. And then there are those small, simple things that don’t fix everything but somehow make it more bearable.
For many people, heat is one of those things.
Heat isn’t a cure. It won’t stop HS from existing. But there’s a reason so many of us reach for a warm compress, a shower, or a heating pad when a flare starts to build. The relief you feel isn’t imagined, it’s rooted in how the body responds to warmth.
Let’s talk about why.
Heat Brings Blood Flow Where It’s Needed
When you apply warmth to your skin, the blood vessels underneath open up. This increases blood flow to the area, bringing oxygen and immune support to tissue that’s inflamed and struggling.
With HS, that inflammation often feels deep, tight, and pressurised. More circulation can help ease that sensation, which is why heat often makes a flare feel a little less “angry” and a little less painful.
Heat Softens What Feels Hard and Stuck
HS nodules can feel like they’re buried under the skin, hard, swollen, and impossible to ignore. Heat gently softens the surrounding tissue, which can reduce that rigid, stretched feeling.
This is especially helpful in areas like the armpits, groin, and under the breasts, where movement, friction, and skin-on-skin contact already make everything more uncomfortable. Even a small amount of softening can make walking, lifting your arms, or just existing feel easier.
Heat Can Help Lesions Drain Naturally
One of the reasons heat is so commonly recommended is because it can encourage natural drainage. Warmth can help bring a lesion closer to the surface so it can open on its own, instead of staying trapped under the skin.
This matters because squeezing or forcing drainage often makes things worse, more inflammation, more scarring, more pain. Heat offers a gentler way to support your body without causing additional trauma.
Heat Helps Calm Pain Signals
Pain doesn’t just live in the skin. When something hurts for a long time, the body tenses up around it. Muscles tighten. Nerves become more sensitive. Everything feels amplified.
Heat helps muscles relax and sends calming signals to irritated nerves. That’s why warmth can reduce throbbing, stabbing, or burning sensations, and why even 10 minutes can sometimes take the edge off when nothing else will.
Heat Soothes the Nervous System Too
Living with HS is exhausting, not just physically, but mentally and emotionally. Chronic pain keeps the body in a constant state of alert, which can actually make pain feel worse.
Warmth tells the nervous system that it’s okay to soften. To breathe. To come out of survival mode, even briefly. That calming effect doesn’t erase HS, but it can lower the intensity of what you’re feeling in that moment.
Heat Makes Daily Care a Little Gentler
Showering, cleaning wounds, changing dressings, these things can be painful and emotionally draining. Using heat beforehand can soften crusting, reduce tenderness, and make care routines feel less harsh.
For many people, this small step makes the difference between avoiding care altogether and being able to show up for their body with a bit more kindness.
Using Heat Safely
Heat works best when it’s gentle:
-
Warm, not hot
-
10–15 minutes at a time
-
Always protect your skin with a cloth
-
Keep the area clean and dry afterward
If heat increases redness, irritation, or pain, stop. Your body will always be the best guide.
