Hyperhidrosis, sometimes referred to as excessive sweating, is a condition that affects at least 1 to 2% of the global population. Despite its prevalence, it remains poorly understood, surrounded by myths and misconceptions that can make life even more challenging for those living with it. These myths not only contribute to stigma but also prevent many from seeking the treatment they need. In this blog, we will examine the myths and facts about hyperhidrosis, aiming to empower individuals with accurate information.
Many people assume hyperhidrosis is simply “sweating too much.” However, it’s a recognised medical condition caused by overactive sweat glands. This isn’t the sweating you experience after a workout or on a hot summer’s day—it’s excessive sweating that can happen at any time, regardless of external temperature or physical activity. Some people may find themselves drenched while sitting at their desks or even in cool, air-conditioned rooms. Hyperhidrosis can disrupt daily life in ways many people don’t realise, with its impact extending far beyond physical symptoms.
One of the most common myths is that hyperhidrosis is rare. It affects millions worldwide—an estimated 365 million people. However, the condition often goes undiagnosed because of the stigma attached to excessive sweating. Many people feel too embarrassed to talk about their symptoms, while others may not even realise that their sweating is abnormal or treatable. This lack of awareness perpetuates the belief that hyperhidrosis is uncommon, leaving many to conceal their condition.
Another misconception is that hyperhidrosis only occurs in hot weather or during physical exertion. While heat and exercise can exacerbate sweating, hyperhidrosis is not seasonal. Cold weather can sometimes worsen symptoms. People with hyperhidrosis often sweat excessively even in winter, especially when bundled up in layers or exposed to indoor heating. For some, stress or anxiety during colder months can also act as a trigger, making winter just as challenging as summer.
The stigma surrounding hyperhidrosis is worsened by the myth that it’s caused by poor hygiene. This belief is not only false but also damaging. Hyperhidrosis is a biological condition, not a result of poor cleanliness. Many people with hyperhidrosis go to great lengths to stay clean, frequently changing clothes, showering multiple times a day, and using antiperspirants religiously. Despite their efforts, the excessive sweating persists because it’s rooted in the body’s overactive sweat glands, not hygiene habits.
Speaking of antiperspirants, many assume they’re a universal fix for hyperhidrosis. While over-the-counter antiperspirants may work for mild sweating, they’re often ineffective for those with moderate to severe hyperhidrosis. People with the condition are likely to need high-strength antiperspirants or specialised devices like iontophoresis machines. Modern medicine has made great strides in treating hyperhidrosis, but it requires tailored solutions based on an individual’s symptoms and needs.
Another harmful misconception is that hyperhidrosis is purely a cosmetic issue. While the visible signs—like sweat marks on clothing or damp palms—are inconvenient, the emotional toll is often much greater. People with hyperhidrosis frequently experience anxiety, embarrassment, and a loss of confidence in social or professional situations. Many avoid shaking hands, wearing certain fabrics, or participating in activities they love. The mental health impact of hyperhidrosis is significant and deserves greater recognition.
It’s also worth addressing the myth that hyperhidrosis only affects the armpits. While underarm sweating (axillary hyperhidrosis) is common, the condition can affect other areas too, such as the hands, feet, face/head, and even the entire body. Each type of hyperhidrosis presents unique challenges. For example, excessive hand sweating (palmar hyperhidrosis) can make it difficult to grip objects or use a touchscreen, while foot sweating (plantar hyperhidrosis) can lead to discomfort and odour in shoes.
Finally, one of the most discouraging myths is that there’s no effective treatment for hyperhidrosis. This simply isn’t true. From prescription medications to specific treatments and products designed specifically for hyperhidrosis, there are numerous ways to manage the condition. In severe cases, surgical options may even be considered. Consulting a healthcare professional is key to exploring the best treatment plan for your specific situation. If you have never talked to your GP before, that should be your first point of contact. Depending on the outcome of that, many people benefit form referral to a dermatologist because these are the only doctors who are trained to manage hyperhidrosis. Resources such as hyperhidrosisuk.org can also help by providing guidance and support.
Understanding the facts about hyperhidrosis is the first step toward breaking the stigma and helping those affected feel supported. By replacing myths with accurate information, we can create a more inclusive environment where people feel empowered to seek help without fear of judgment.
