Why Do I Sweat So Much When I Workout?

If you’re wondering why you sweat so much when you workout, you’re not alone. Many people find that they sweat excessively when they exercise, and it can be quite frustrating. While there are a number of possible explanations, the most likely cause is simply that you’re working hard and your body is responding accordingly. So, next time you find yourself sweating buckets during a workout, don’t worry – it’s just your body doing its job!

Common Causes of Excessive Sweating

Excessive sweating during physical activity is a common occurrence and can be caused by a variety of things. It can range from being a form of natural body cooling, to a sign of an underlying health condition. Understanding the causes of excessive sweating can help you pinpoint what’s causing it and how to address it. Let’s look at some of the common causes of excessive sweating.


Hyperhidrosis is the medical term for excessive sweating which is not proportional to environmental temperature or physical activities. It can significantly disrupt a person’s daily activities, leading to feelings of embarrassment and self-consciousness. Hyperhidrosis often starts in early adulthood and can be more pronounced in certain areas, such as the palms of the hands, soles of the feet, forehead and underarm area. The underlying cause of hyperhidrosis is currently unknown but it has been suggested that excessive sweating may be an inherited trait. There are various treatments available to effectively reduce or stop perspiration which may include prescription antiperspirants or oral medications. In some cases, botulinum toxin injections have been used to target sweat glands and lessen symptoms associated with hyperhidrosis.


Excessive sweating can also be attributed to certain medications. Many drugs such as birth control pills and blood pressure medications can cause increased perspiration. Stimulants like diet pills, caffeine, and decongestants also trigger an increase in sweat production. Antibiotics may contribute to smaller extent as well.

Certain antidepressants have been known to induce excessive sweating as a side effect, particularly selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs). MAOIs (monoamine oxidase inhibitors) are rarely prescribed, but the sweat production side effects can be severe in certain people taking them.

Sweating related to medication does not respond to over-the-counter products or topical solutions, but people suffering from medication-related sweating should speak with their doctor about other treatment options.


Sweating excessively when feeling anxious and under stress is a common occurrence. Anxiety often leads to an overactive sympathetic nervous system, which triggers perspiration and other physical reactions in response to stress. As your body perceives the stressors, it sends a message to your sympathetic nervous system, causing your heart rate and breathing rate to increase, blood vessels to dilate and sweat glands to activate.

When you experience extreme anxiety, sweating can become so severe that it has a significant impact on your quality of life. People dealing with excessive sweating due to anxiety may need to change clothes throughout the day and may be self-conscious about things like shaking hands or speaking in front of others.

It is important to talk with healthcare professionals if you have concerns about excessive sweating due to anxiety or any other potential causes. There are a variety of treatments available that can help reduce anxiety-induced sweats including cognitive behavioral therapy (CBT), lifestyle changes, medications such as antidepressants and antianxiety drugs, biofeedback therapy and more.

Tips to Reduce Sweating During Exercise

Many people find that they sweat a lot when they exercise which can lead to discomfort, self-consciousness and make it more difficult to stay focused on the task at hand. The good news is, there are a few steps you can take to reduce the amount of sweat you produce when you workout. These tips can help you keep your body temperature regulated while also improving your performance. Let’s look at a few of these methods in more detail.

Wear moisture-wicking clothing

When preparing for your workout, opt for clothing made of synthetic materials and fabrics with moisture-wicking properties. These special properties help move sweat away from the body, effectively keeping sweat from building up on the skin and saturating clothing. Look for items with labels that say “moisture wicking”, “breathable” or “quick-dry”; these are usually found in sportswear–tops, bottoms, socks and shoes. Additionally, wear clothing that is specifically designed to keep you cool; some sports apparel incorporate cooling fabrics that absorb heat and draw it away from the body while keeping you feeling dry. Athletic apparel isn’t just helpful to regulate body temperature during a workout session. Tight fitting garments also create a barrier against cold weather while acting as insulation to keep heat close to your skin without letting much sweat escape.

Exercise in a cool environment

When you exercise in a humid and hot environment your body has to work harder to regulate its temperature, thus increasing your sweat production. To reduce excess sweating during exercise, try to work out indoors when possible or in environments with air conditioning. If you’re exercising outside, opt for early mornings or late evenings when temperatures are cooler. Additionally, consider investing in a cooling towel that is placed on the neck during exercise for an extra bit of relief during workouts.

Drink plenty of fluids

Staying adequately hydrated is crucial to help you regulate your body temperature while exercising. Drinking plenty of fluids—especially water—lawyers up your body’s ability to regulate its own temperature, resulting in fewer sweat-inducing episodes. Drink eight ounces of water at least a half hour before you exercise and two to three glasses (eight ounces each) during every hour that you’re still active; some general guidance suggests that 64 ounces should be consumed daily. Sports drinks are great for replenishing both electrolytes and carbohydrates lost through sweat, but cardio sessions lasting less than 60 minutes shouldn’t require anything more than liquid H2O.

Other Causes of Excessive Sweating

Stress, anxiety, and hormonal changes can often cause excessive sweating. While physical activity is a major contributing factor, there are other causes of sweating that you should consider. In this section, we’ll explore other possible causes of excessive sweating and discuss how to manage them.

Hormonal imbalances

Hormonal imbalances are one of the more common causes of excessive sweating. In particular, hyperthyroidism and menopause may both cause individuals to sweat more than usual. Hyperthyroidism is a condition in which the thyroid produces an increased amount of hormones, leading to an increased metabolic rate and resulting in excessive perspiration. Menopause is a period in which women’s hormones become naturally imbalanced due to changes related to aging, and this can also lead to increased sweating.

Individuals with suspected hormonal imbalances should consult with their primary care provider or endocrinologist as they may be able to address the underlying condition that is causing the sweating. Treatment for hormonal imbalances may include medication and lifestyle modifications such as dietary changes or stress-reduction techniques.

Poor diet

Our diets can have a significant impact on our body’s ability to regulate temperature and cortisol levels. Eating processed foods with high sugar content, for instance, can cause the release of large amounts of insulin into the body. This triggers extra sweat in order to reduce the level of sugar in your bloodstream. In addition, a diet low in fiber or protein can easily disrupt digestion and hormones, leading to increased sweating during workouts. Eating small meals regularly helps regulate your metabolism and promotes healthy digestion which inevitably contributes to an optimal functioning body.

Certain medical conditions

Certain medical conditions can cause excessive sweat even when the body is not exerting itself. Hyperthyroidism, an overactive thyroid can lead to excessive sweating, along with feeling anxious and having a rapid heart rate. Diabetes can also be the root cause of one’s sweat glands overreacting and producing too much sweat. Other medical causes of excessive sweating include some forms of cancer, low blood sugar (hypoglycemia), menopause, and other hormonal disturbances.
It is important to check with your doctor if you feel yourself sweating more than usual even without physical exercise or experiencing hot weather. It may be a sign that something else is wrong with your body and catching it early could help improve your overall health in the long run.

When to Seek Medical Attention

Sweating is a normal part of exercising, but if you find that you are sweating excessively during and after a workout, you should consider seeking medical attention. Excessive sweating can be caused by a variety of factors, including hormonal imbalances, dehydration, and certain medical conditions. Therefore, it is important to understand why you are sweating excessively and to determine whether or not it is cause for concern. In this section, we will discuss when it is necessary to seek medical attention.

If you experience excessive sweating for more than 6 months

If you experience excessive sweating for more than 6 months, it is important to seek medical attention. There are several medical conditions that can cause excessive sweating and they should be discussed with your doctor. Some causes of excessive sweating may include:

– Hyperthyroidism: This is an overactive thyroid gland which can increase the body’s temperature in response to exercise or stress, resulting in excessive perspiration.
– Diabetes: Diabetes can disrupt the body’s ability to regulate its temperature, leading to excessive perspiration during physical activity.
– Endocrine Disorders: The endocrine system is responsible for creating and controlling hormones in the body and any disruption of this process can also lead to increased sweat production.
– Heat Illnesses: Inadequate rest and hydration are often factors when exercising outdoors in very hot climates, leading to an increased risk for heat illnesses such as Heat Exhaustion or Heat Stroke which require immediate medical attention.
– Medication Side Effects: Sweating can be a side effect of some medications so it is important that any medications you may be taking are discussed with your doctor before changes are made to your regimen.

It is also important to note that sweat glands can become habitually overactive, so if you have consistently been involved in intense exercise or other physical activity without adequate rest and hydration breaks, it could contribute to persistent heavy perspiration. If you have been experiencing excessively sweaty workouts for more than 6 months – along with any associated symptoms like fatigue, fever or chills – it’s time to visit a healthcare professional for further evaluation and treatment options.

If you have other symptoms such as fever, chills, or chest pain

It’s normal to sweat when you’re working out, especially if your body is pushing itself hard. However, if you’re experiencing other symptoms when you work out, such as fever, chills, or chest pain, you should see a doctor right away. It could be a sign of something more serious.

When exercising in hot weather or at high altitudes it’s important to make sure that your body stays cool and hydrated to avoid heat-related illnesses such as heat exhaustion and heat stroke. If you become dizzy or faint while exercising it’s important to immediately stop and cool down right away. If your symptoms persist after a few minutes of rest or do not get better with hydration then seek medical attention.

Fever with sweating can indicate a serious infection or other health condition so please consult your doctor for further evaluation. Chest pain that worsens with activity may indicate a heart condition; therefore you should consult your doctor if these symptoms arise during exercise sessions.

If you are concerned about your excessive sweating

If you are concerned about your excessive sweating, it is important to speak to a medical professional about your condition. Your doctor can help you determine the cause and the best treatment for your health and lifestyle.

In many cases, excessive sweating is part of a larger overall health issue. It may be caused by an underlying medical condition like hyperhidrosis or menopause. It could also be a sign of an infection or metabolic disorder such as diabetes or thyroid disease. Therefore, it is important to consult with a doctor to make sure that no serious illness is present.

If there is no underlying medical condition causing your profuse perspiration during exercise, your doctor may recommend lifestyle changes such as adjusting diet and exercise levels, wearing breathable fabrics when working out, staying adequately hydrated and using antiperspirants or topical medications specifically designed to reduce excessive sweating.

Your doctor might also recommend counseling if the problem persists in order to help you manage the situation mentally and emotionally. The right treatment plan will help you understand why you sweat so much when exercising and provide information on what steps to take in order to reduce excessive sweating during physical activity.

Treatment Options

Excessive sweating when working out can be a source of annoyance and embarrassment. If you find yourself sweating heavily for no apparent reason during your workouts, it’s important to find a treatment plan that’s right for you. In this section, we’ll explore some of the treatment options available that can help reduce the amount of sweat you experience during physical activity.


Antiperspirants are products designed to treat excessive sweating (hyperhidrosis) and can be an effective option for reducing sweat. Most antiperspirants contain aluminum salts, which temporarily form a barrier to plug sweat ducts. Common forms of antiperspirant include sticks, pads, creams, lotions, gels, sprays and mouses. Antiperspirants are not only used for excessive sweating on the arms or hands but can also be used to treat foot and/or facial sweating.

For maximum benefit and effectiveness when treating hyperhidrosis, antiperspirants should be applied two times per day — once in the morning and then again before bedtime – especially after you’ve showered. Make sure your skin is dry when applying the product so it will have proper time to absorb into your skin; this may result in less visible wetness overnight. It’s also important to use a higher strength product (e.g., Clinical Strength), as these products have more aluminum salts which plug sweat ducts more effectively than regular OTC products. Lastly, keep in mind that depending on severity of your condition you may need prescription-strength antiperspirant that is available through a doctor or dermatologist’s office only.

Botox injections

Botox injections are a common treatment option for those suffering from hyperhidrosis, or excessive sweating. In very small doses, Botox works by blocking the release of a neurotransmitter called acetylcholine. Acetylcholine is responsible for activating the sweat glands and when a small dose of Botox is injected into the area, it prevents your body from sending out the signal to make you sweat.

The results of these injections can be seen within a few days and typically last for six months to one year. For some people, one injection can last up to 18-24 months. Botox treatments may need to be repeated several times as the effects wear off. The good news is that over time, with repeated treatments, some patients stop sweating altogether in that area of their body.

Side effects of using Botox are typically mild and include local numbness or tenderness at the injection site. It’s important that only qualified medical personnel perform these injections in order to minimize potential adverse reactions


Surgery may be recommended for individuals with extremely severe cases of excessive sweating, especially if other treatments have proven ineffective. Two types of surgery are most commonly used to treat excessive sweating.

The first type is sympathectomy— also known as endoscopic thoracic sympathectomy (ETS)— which involves cutting or blocking nerves that provide signals to sweat glands. The procedure is believed to work best on hyperhidrosis affecting the hands, armpits, and feet. A doctor typically performs the operation using a tiny endoscope inserted through a small incision in the chest wall between the ribs.

The second type of surgery is called suction curettage or liposuction and uses a suction technique to remove sweat glands from the area being treated. The number of glands removed depends on how many are present and located in the affected area(s). Liposuction is usually used when an individual did not respond favorably to ETS treatment, although it may be recommended with ETS at times as well.
