Hello. I am Dr. Hwang Sang-cheol, a specialist in the research and treatment of the autonomic nervous system.
Quite a few people experience discomfort due to excessive sweating on their hands, feet, or face. However, in my practice, I often notice an interesting difference. Some patients say they’ve had sweaty hands since elementary school, while others report that excessive sweating on their face or scalp suddenly began after they became adults. Even though they may appear to be the same condition—hyperhidrosis—the onset and causes can differ, and the treatment approach may vary accordingly. Today, I’ll explain in detail the differences between hyperhidrosis that has been present since childhood and hyperhidrosis that developed in adulthood.
Hyperhidrosis that begins in childhood is often influenced by constitutional factors.
If you’ve had excessive sweating on your palms or soles since elementary or middle school, you may have primary hyperhidrosis. In such cases, no specific underlying medical condition is usually found; it is generally understood that the autonomic nervous system stimulates the sweat glands with a relatively sensitive response. If you have long experienced repeated episodes of sweaty palms—such as when you’re nervous or about to give a presentation—that cause your hands to sweat so much they dampen your exam paper, or if you find shaking hands uncomfortable, it is quite common for this to fall under this category. Although many people endure these symptoms, assuming there is no major health issue even if they persist for a long time, the inconvenience in daily life can be significant.
In some cases, there is also a family history of the condition.
In the clinic, we often hear patients mention that their parents or siblings also had excessive sweating of the hands and feet. While this is not true for all patients, some studies have reported a family history in cases of primary hyperhidrosis. Therefore, if your symptoms began in childhood and other family members have similar symptoms, it may be helpful to consider constitutional factors as well.
If you develop hyperhidrosis suddenly as an adult, you should look into other possible causes.
On the other hand, if you’ve suddenly started sweating more since becoming an adult, a slightly different approach is needed. In particular, if you previously had no specific issues but have experienced increased sweating on your face, head, or back in recent months, changes in your lifestyle or health may be contributing factors. Therefore, it is important to determine when the symptoms began and identify any changes in your living environment or health that occurred around that time.
Recent lifestyle habits can also have an impact.
If you’ve been going out for drinks more often lately, have started working night shifts, or have irregular sleep patterns, the balance of your autonomic nervous system may be disrupted, leading to increased sweating. When our bodies maintain a consistent daily rhythm, the autonomic nervous system functions relatively stably. However, if sleep deprivation and an irregular lifestyle persist, the sympathetic nervous system can become overactive, and during this process, you may feel that you’re sweating more than usual.
Stress is also a factor that cannot be ignored.
Many people have experienced their hands suddenly getting sweaty or their face flushing when under severe stress. In stressful situations, the sympathetic nervous system is activated, causing the heart rate to increase and stimulating the sweat glands. If this state repeats over a long period, you may feel like you sweat more easily than before. Of course, not all cases of hyperhidrosis are caused by stress, but it is a common factor that contributes to the worsening of symptoms.
Alcohol and caffeine can also have an effect.
Some people experience facial flushing and excessive sweating after drinking alcohol. This is because alcohol dilates blood vessels and can also affect the autonomic nervous system. Caffeine, too, can stimulate the sympathetic nervous system in some people, leading to increased sweating. Therefore, if you’ve recently increased your alcohol consumption or caffeine intake significantly, it may be helpful to review your lifestyle habits as well.
You should also take hormonal changes into account.
If your hyperhidrosis suddenly worsens as an adult, hormonal changes may be one of the possible causes. Changes in thyroid function or hormonal fluctuations around menopause are known to affect sweat production. Therefore, if your symptoms began suddenly or are accompanied by other systemic symptoms, it is advisable to consult a healthcare professional to determine the cause.
Depending on the cause, the treatment method may vary.
Hyperhidrosis is not a condition that can be treated in the same way for everyone. Primary hyperhidrosis, which has persisted since childhood, and hyperhidrosis that began in adulthood may have different causes, so the approach to managing them may also differ. When lifestyle factors play a significant role, managing sleep and stress may be important; however, if another medical condition is suspected, evaluating that underlying cause should take priority. Examining both the onset and nature of the symptoms helps in developing a more appropriate management plan.
If your excessive sweating has suddenly gotten worse, you should check this out.
If you’ve been fine up until recently but have suddenly started sweating a lot, it’s a good idea to take a look at your recent lifestyle rather than simply attributing it to your constitution. Please check whether you’ve been drinking more, getting less sleep, experiencing increased stress, or taking any medications. Additionally, if you experience severe night sweats or other symptoms such as weight changes or fatigue, it may be helpful to consult a healthcare professional to determine the cause.
Conclusion
Hyperhidrosis cannot always be explained simply as a tendency to sweat heavily. Hyperhidrosis that has persisted since childhood is often influenced by constitutional factors and the sensitivity of the autonomic nervous system, while hyperhidrosis that begins in adulthood may result from a combination of various factors, such as lifestyle habits, stress, sleep, and hormonal changes. The key is not to focus solely on the sweating itself, but to also examine why it has increased. If your hyperhidrosis has suddenly worsened recently, or if you have long been bothered by sweaty hands and feet, please take a moment to reflect on when your symptoms first began. Understanding the cause is the first step toward managing the condition.
