Why Are My Hands Always Sweaty: Causes, Symptoms, and Treatments

Excessive sweating is a common problem that affects millions of people worldwide. Sweating is a natural process that helps regulate body temperature, but when it becomes excessive, it can be a cause of embarrassment and discomfort. One specific area where this condition can be particularly problematic is the hands. If you’re someone who suffers from sweaty palms, you know how uncomfortable it can be to shake hands or hold your partner’s hand. It can also make simple tasks such as writing or typing more difficult. In this blog post, we’ll explore the causes and symptoms of sweaty hands, as well as the various treatment options available to manage this condition.



Do you often find yourself struggling with sweaty hands, no matter what the temperature is? Does your perspiration seem to be excessive and out of control? You’re not alone. Millions of people around the world suffer from hyperhidrosis, a medical condition that causes excessive sweating.

Hyperhidrosis affects approximately 3% of the global population and can significantly impact a person’s daily life. It can lead to embarrassment, social anxiety, and decreased self-confidence. The condition usually begins in childhood or adolescence and continues throughout adulthood. However, some people develop hyperhidrosis later in life due to medical conditions such as diabetes or thyroid issues.

There are two types of hyperhidrosis – primary and secondary. Primary hyperhidrosis typically affects the palms, soles, underarms, and face. It’s not caused by any underlying medical condition and usually occurs when the nerves responsible for triggering sweat production become overactive. Secondary hyperhidrosis, on the other hand, is caused by an underlying medical condition and can affect the entire body.

In this article, we’ll explore the causes, symptoms, and treatments available for sweaty hands. We’ll also discuss how hyperhidrosis can be managed to improve your quality of life. So, let’s dive in and learn more!

What Causes Excessive Sweating on Hands?



Hyperhidrosis is a medical condition characterized by excessive sweating beyond what is necessary to regulate body temperature. The sweat glands overreact, producing more sweat than the body needs. This can be caused by primary hyperhidrosis or secondary hyperhidrosis.

Primary Hyperhidrosis

Primary hyperhidrosis is a health condition that causes excessive sweating in specific areas of the body, such as the palms, soles of the feet, face, and underarms. It affects approximately 3% of the population and usually begins during childhood or adolescence. The exact cause of primary hyperhidrosis is unknown, but it is believed to be related to genetics.

People with primary hyperhidrosis may experience emotional and social distress due to their condition. They may avoid certain activities or situations, which can affect their quality of life. Treatment options for primary hyperhidrosis include antiperspirants, medications, and surgery.

Secondary Hyperhidrosis

Secondary hyperhidrosis is excessive sweating caused by an underlying medical condition. It can occur at any age and affects both men and women. Some common causes of secondary hyperhidrosis include diabetes, thyroid issues, infections, and side effects of medication.

Unlike primary hyperhidrosis, secondary hyperhidrosis typically affects the whole body, rather than just specific areas. It can also be accompanied by other symptoms, such as fever, rapid heartbeat, or weight loss.

The treatment of secondary hyperhidrosis depends on the underlying medical condition causing it. Addressing the underlying condition can often reduce or eliminate excessive sweating.

In conclusion, hyperhidrosis is a medical condition that can significantly affect an individual’s quality of life. Identifying whether it is primary or secondary hyperhidrosis is essential to determine the most effective treatment options available. Seeking medical advice is strongly recommended for anyone experiencing excessive sweating.

Medical Conditions

Medical Conditions

Excessive sweating on hands can often be a sign of underlying medical conditions. In this section, we will explore some of the most common medical conditions that may cause sweaty hands: diabetes, thyroid issues, and infections.


Diabetes is a metabolic disorder that affects how your body processes glucose (sugar). People with diabetes have high levels of glucose in their blood, which can damage nerves and blood vessels throughout the body, including those that regulate sweating. As a result, people with diabetes may experience excessive sweating on their hands and feet.

Thyroid Issues

The thyroid gland produces hormones that regulate metabolism, energy, and body temperature. When the thyroid gland is overactive (hyperthyroidism) or underactive (hypothyroidism), it can cause a range of symptoms, including excessive sweating on the hands. This is because the thyroid gland plays a key role in regulating the body’s temperature and sweat production.


Certain infections, particularly those that cause fever, can also trigger excessive sweating on the hands. For example, bacterial infections like tuberculosis or endocarditis can lead to night sweats and clammy palms. Viral infections like HIV or hepatitis can also cause sweating as the body tries to fight off the infection.

In summary, if you are experiencing sweaty hands along with other symptoms like weight loss, fatigue, or frequent infections, it may be worth getting checked for underlying medical conditions like diabetes or thyroid issues. By treating the underlying condition, you may be able to reduce or eliminate your symptoms of excessive sweating.


Anxiety can be a major contributor to sweaty hands. When we experience anxiety, our body activates the “fight or flight” response. This is an evolutionary response designed to prepare us to either fight off a threat or flee from danger. The nervous system releases adrenaline and other hormones that increase heart rate, blood pressure, and respiration while constricting blood vessels and reducing blood flow to non-essential areas like the skin. This results in the palms of our hands becoming sweaty as the body tries to cool itself down.

The nervous system plays a key role in this process. It is responsible for transmitting signals between the brain and different parts of the body, including the sweat glands in the palms of our hands. When we experience anxiety, these signals become overactive, leading to excessive sweating.

For some people, anxiety-induced sweaty hands can be a chronic condition. They may experience it when they are in social situations, public speaking, or even just trying to meet new people. This can be very debilitating and affect their quality of life.

Fortunately, there are treatments available for anxiety-induced sweaty hands. One of the most effective treatments is cognitive-behavioral therapy (CBT), which helps people change the way they think about and respond to anxiety-provoking situations. Medications can also be used to treat anxiety, including antidepressants and anti-anxiety medications.

In addition to these treatments, there are also lifestyle changes that can help reduce anxiety and its associated symptoms. These include regular exercise, mindfulness meditation, and deep breathing exercises.

Overall, anxiety can be a major contributor to sweaty hands. Understanding the role of the nervous system and the fight or flight response is important in developing effective treatments for this condition. With the right treatment and lifestyle changes, those who suffer from anxiety-induced sweaty hands can lead a more comfortable and fulfilling life.



Family history and inheritance play a significant role in determining whether or not an individual will experience excessive sweating on their hands. Studies have shown that if one or both parents suffer from hyperhidrosis, there is a greater chance that their children will as well.

Hyperhidrosis is believed to be a genetic condition, meaning that it is passed down through family genes. While the specific gene responsible for hyperhidrosis has not yet been identified, researchers believe that it is likely inherited in an autosomal dominant pattern. This means that only one copy of the gene is needed to produce the condition, and each child of an affected parent has a 50% chance of inheriting the gene.

In addition to genetics, other factors can also contribute to the development of hyperhidrosis. For example, anxiety and stress can trigger excessive sweating, even in individuals who do not have a family history of the condition. However, people who have a genetic predisposition to hyperhidrosis may be more likely to experience symptoms in response to stressors.

If you have a family history of hyperhidrosis, it may be worthwhile to speak with your doctor about your risk of developing the condition. While there is no cure for hyperhidrosis, there are a variety of treatment options available to help manage symptoms. By understanding your risk factors and seeking appropriate treatment, you can improve your quality of life and reduce the impact of excessive sweating on your daily activities.

Symptoms of Sweaty Hands

Symptoms of Sweaty Hands

Sweaty hands are characterized by an excessive amount of perspiration on the palms, which can lead to wet palms, clammy hands, and an unpleasant odor. While sweating is a natural process that helps regulate our body temperature, excessive sweating on the hands can be uncomfortable, embarrassing, and even interfere with daily activities.

Wet palms are one of the most common symptoms of sweaty hands. This can make it difficult to grip objects, write with a pen or pencil, or perform other manual tasks. In addition, the moisture from the perspiration can cause the skin to become more prone to infections or irritations.

Clammy hands are another symptom of sweaty hands. This refers to a sticky or damp feeling on the palms, even when there is no visible perspiration. Clammy hands can feel uncomfortable or awkward, especially when shaking hands with others or engaging in social situations.

An unpleasant odor is also a common symptom of sweaty hands. This can be caused by the bacteria that thrive in warm, moist environments, such as the palms of our hands. The smell can be embarrassing and can make individuals self-conscious about shaking hands or being close to others.

If you experience any of these symptoms, it’s important to talk to your doctor or a dermatologist. They can diagnose the underlying cause of your sweaty hands and recommend appropriate treatment options. In some cases, lifestyle modifications, such as avoiding triggers or using antiperspirants, may be effective. Other treatment options include prescription medications or medical procedures, such as iontophoresis or surgery.

Overall, if you are experiencing symptoms of sweaty hands, it’s important to seek medical attention. With the right diagnosis and treatment plan, you can manage your symptoms and improve your quality of life.

How to Stop Your Hands from Sweating


Antiperspirants are a common solution for those seeking relief from sweaty hands. These products work by temporarily blocking sweat ducts to reduce perspiration. One of the most popular active ingredients in antiperspirants is aluminum chloride hexahydrate, which can be found in both over-the-counter and prescription antiperspirants.

Aluminum chloride hexahydrate works by dissolving in sweat, creating a plug that blocks the sweat ducts and reduces perspiration. It is typically found in antiperspirant products as a solution or gel.

Topical creams are another option for those looking to combat sweaty hands. These creams often contain aluminum chloride in higher concentrations than traditional antiperspirants. They are typically applied before bed and washed off in the morning.

While antiperspirants and topical creams can be effective in reducing sweat production, they may not work for everyone. Additionally, some people may experience irritation or allergic reactions to the active ingredients in these products.

It is important to note that antiperspirants should not be used on broken or irritated skin. Individuals with kidney disease or Alzheimer’s should also consult with their healthcare provider before using antiperspirants due to the potential absorption of aluminum.

Overall, antiperspirants and topical creams containing aluminum chloride hexahydrate can provide relief for those suffering from excessive sweating on their hands. However, it is important to read labels carefully and consult with a healthcare provider if you have any concerns or pre-existing conditions.



Iontophoresis is a non-invasive treatment that uses electrical currents to reduce excessive sweating on the hands, feet, and underarms. During the procedure, the affected area is placed in a water bath, and a low electrical current is passed through it.

The exact mechanism of action is not well understood, but it is believed that the electrical current changes the pH of the skin, resulting in the temporary blockage of sweat glands. The treatment typically takes 20-30 minutes, and multiple sessions are required to achieve optimal results.

Iontophoresis is an effective treatment for hyperhidrosis, which is a medical condition that causes excessive sweating. It can significantly improve the quality of life for those who suffer from this condition, as well as reduce the risk of skin infections and social anxiety.

One of the major advantages of iontophoresis is that it is non-invasive and does not require any anesthesia. Additionally, the side effects are minimal and include mild discomfort or redness at the site of treatment, which usually resolves within hours.

Although iontophoresis is generally safe, it may not be suitable for everyone, such as those with pacemakers or metal implants. It is important to consult with a healthcare professional before undergoing this treatment.

In summary, iontophoresis is a safe and effective treatment option for those suffering from excessive sweating. Its non-invasive nature and minimal side effects make it an attractive alternative to more invasive procedures. If you are struggling with hyperhidrosis, talk to your doctor about whether iontophoresis might be right for you.



In some cases, excessive sweating on hands may be caused by an underlying medical condition, such as hyperthyroidism or anxiety. In such cases, medications may be prescribed to manage the symptoms of the condition and reduce the amount of perspiration.

Two types of medications that are commonly used to treat excessive sweating are anticholinergics and beta blockers.


Anticholinergics work by blocking the neurotransmitter acetylcholine, which is responsible for stimulating the production of sweat. By reducing the amount of acetylcholine in the body, anticholinergics can help to prevent excessive sweating.

One example of an anticholinergic medication that may be prescribed for sweaty hands is glycopyrrolate. This medication is often used to treat conditions such as hyperhidrosis, and is available in both pill and topical cream forms.

While anticholinergics can be effective at reducing sweating, they can also cause a number of side effects, including dry mouth, blurred vision, and constipation. As such, they should only be taken under the guidance of a healthcare professional.

Beta Blockers

Beta blockers are a type of medication that works by blocking the effects of adrenaline and other stress hormones in the body. By reducing the body’s response to stress, beta blockers can help to reduce sweating.

While beta blockers are not specifically designed to treat excessive sweating, they may be prescribed for individuals who experience sweating as a symptom of anxiety or panic attacks. Some common beta blockers include propranolol and atenolol.

Like anticholinergics, beta blockers can cause a range of side effects, including dizziness, fatigue, and low blood pressure. As such, they should only be taken under the guidance of a healthcare professional.

Overall, while medications can be effective at reducing excessive sweating, they are not always the best option for everyone. Before starting any new medication, it is important to speak with a healthcare professional to discuss possible side effects and to determine if the medication is right for you.



For individuals with severe cases of sweaty hands, surgery is often considered as a last resort. There are two types of surgeries that can be used to treat excessive sweating in the hands: endoscopic thoracic sympathectomy (ETS) and lumbar sympathectomy.

Endoscopic Thoracic Sympathectomy

ETS is a minimally invasive surgery that involves cutting or clamping the sympathetic nerves responsible for triggering sweat production in the hands. This procedure is usually performed under general anesthesia and involves making small incisions in the chest wall.

The success rate of ETS is high, with many patients experiencing a significant reduction in their sweating after the operation. However, like all surgical procedures, there are risks associated with ETS, including nerve damage, bleeding, infection and compensatory sweating in other parts of the body.

Lumbar Sympathectomy

Lumbar sympathectomy is a less common surgical procedure used to treat excessive sweating in the hands. This procedure involves cutting or clamping the sympathetic nerves in the lower back that control sweating in the hands and feet.

Like ETS, lumbar sympathectomy is not without its risks, and it may also result in compensatory sweating in other areas of the body. However, for some individuals, lumbar sympathectomy may be a more suitable option than ETS.

It’s important to note that surgery should only be considered when other non-invasive treatments have failed, and after consultation with a qualified healthcare professional.

In conclusion, while surgery is an effective treatment option for excessive sweating in the hands, it should always be approached with caution, taking into account the potential risks and benefits.



Sweaty hands can be a frustrating and embarrassing experience, but there are several treatment options available to help improve your quality of life. Depending on the severity of your condition, you may want to consider using antiperspirants, undergoing iontophoresis treatments, taking medications, or even opting for surgery.

Antiperspirants are a popular choice for people with sweaty hands as they are easy to use and can be purchased over-the-counter or prescribed by your doctor. These products work by blocking sweat ducts and reducing the amount of perspiration produced by the body. However, it’s important to note that they can cause skin irritation and may not be effective for everyone.

Iontophoresis is another treatment option that involves using electrical currents to reduce sweating. This method is typically used for people with more severe cases of hyperhidrosis and can require several sessions before results are noticeable. While it can be effective, it can also be time-consuming and may not be covered by insurance.

Medications such as anticholinergics and beta blockers can also be used to help control excessive sweating. However, these drugs can have side effects and may not be suitable for everyone.

In some cases, surgery may be the best option for treating sweaty hands. Endoscopic thoracic sympathectomy (ETS) and lumbar sympathectomy are two surgical procedures that are commonly used to treat hyperhidrosis. While these surgeries can be effective in reducing sweating, they also carry risks and potential complications.

Ultimately, the best treatment option for you will depend on the severity of your condition and your individual needs. If you’re struggling with sweaty hands, it’s important to talk to your doctor to explore all of your treatment options and find the one that works best for you.
