How to Prevent Underarm Sweat

Underarm sweat can be a source of discomfort and anxiety, but with the right approach, you can stay fresh and confident. Deodorants only mask the odor of sweat, so to truly prevent sweating, you need to take proactive steps to address the underlying issues with your sweat glands. This might involve using antiperspirants correctly, changing your lifestyle, or even considering stronger medical treatments.

Diagnose the issue specifically. Before purchasing the usual deodorant from stores, take a moment to identify your exact problem so you can select the right product. For some, the main issue is body odor, while for others, the biggest concern is the unsightly stains left by sweat, which can impact confidence.

• If you are dealing with both body odor and sweat stains, you need a solution that can address both issues separately. Deodorant alone won’t stop underarm sweating, although it can eliminate odors.
• You can't completely stop your body from sweating without medical intervention, which is typically reserved for severe cases. The body must be able to excrete salts and toxins through the skin to survive.

Choose a product that suits your specific needs. Depending on your issue, you may need an antiperspirant, a product that prevents sweating, or a combination of both. In some cases, it's advisable to consult with a doctor to get a prescription for stronger antiperspirant products available on the market.

• If you've had issues with body odor, you should use a deodorant with natural, neutral ingredients. These will help mask the smell of sweat, but you should also consider other hygiene methods to improve the issue you're dealing with. The later sections of this article will provide helpful hygiene tips to address the problem.
• If you’ve struggled with sweat stains, most antiperspirants on the market contain aluminum chloride hexahydrate, which is effective in controlling the amount of sweat produced.

Try making your own natural deodorants. Recent studies have suggested that aluminum-based antiperspirants may be linked to breast cancer and other health issues. While this remains a controversial topic, many people prefer to use natural products. There are natural deodorants available in stores, but you can also create your own to manage underarm sweat.

• Mix equal parts baking soda and water to form a paste, apply it to your underarms, and leave for 20-30 minutes before washing off.
• Try apple cider vinegar or malt vinegar to neutralize odor-causing bacteria. This will help your underarms stay dry by reducing sweat production and keeping you fresh.
• Use a mixture of lemon juice and tomato powder before bedtime and leave it on for 15 minutes.
• Make a mix using walnut and eucalyptus leaves.
• Some people claim that herbal tea acts as a "coolant" and helps prevent sweating.

Use products correctly. In general, if you're trying to combat the negative effects of underarm sweat, it's important to apply antiperspirants or deodorants to clean skin before bed, first thing in the morning, and whenever you shower. Always wash your hands thoroughly with soap and water, dry them, then apply a thin layer of deodorant or antiperspirant to keep your underarms dry.

• Some people only use deodorants before going out or when getting dressed. However, once you’re sweating, it’s impossible to control body odor. You should always clean your underarm area first.
• If you feel drenched in sweat, applying antiperspirants or deodorants on top of sweaty skin won’t help control odor. Instead, clean your underarms with soap and water, try to cool down your body, and then apply deodorant.

Wash your clothes after every wear. Especially if your shirt has absorbed sweat, washing it immediately after wearing is crucial. Once again, underarm odor is not directly caused by sweat but by bacteria that thrive on dried sweat.

• If you don't wash off the sweat from your clothes, bacteria from your sweat will accumulate over time, making the odor worse. Changing clothes frequently and keeping them clean is vital.
• If you sweat excessively, you should change shirts more often, even before your next shower. If you anticipate heavy sweating at work, keep an extra shirt in your bag just in case.

Wear an undershirt. A simple white T-shirt can absorb sweat effectively, preventing it from soaking through to your outer shirt. If you sweat a lot, consider wearing an inner layer to keep sweat from seeping through to your outer shirt.

• Like your outer shirt, the undershirt also needs regular washing to avoid unpleasant smells.

Shave your underarm hair. If you struggle with excessive sweating from this area, sometimes removing underarm hair can help. While it doesn’t cool the area or reduce sweat production, it prevents sweat buildup, which contributes to a stronger odor.

• It's important to note that body hair, including underarm and facial hair, actually helps cool the body in high temperatures by gathering sweat and aiding in its evaporation. Shaving body hair may reduce underarm sweat but could increase overall body perspiration slightly.

Modify your diet. Recent studies show that certain foods, especially pungent ones, can impact the smell of your sweat. If you're prone to sweating heavily, know that your diet can make the situation worse.

• Onions, garlic, and other allium foods release sulfur, which creates a strong odor when the sweat dries. Some spices like anise (also known as star anise), fennel, and curry powder have also been found to cause odors under the arms, as well as cruciferous vegetables like cabbage or broccoli.
• Eating a lot of red meat, dairy, or drinking alcohol can also make your sweat smell more distinct, although people may adapt to the smell over time.
• The capsaicin in spicy peppers stimulates the nerve receptors in your mouth, mimicking the sensation of heat. This tricks your body into thinking you’re too hot, causing your brain's hypothalamus to signal your body to sweat more.

Exercise to reduce your BMI. If your BMI is higher than normal for your body, you’ll sweat more to regulate your body temperature. To reduce underarm sweat, consider adding cardio workouts to your routine along with weight loss exercises. Let the sweat flow as you exercise.

• The quickest way to lose weight is by increasing physical activity and decreasing daily calorie intake to a stable level. Try replacing fried foods, dairy, and red meat with lean protein sources like beans, chicken, and eggs, while boosting your intake of whole grains and vegetables.
• Drink plenty of water throughout the day, and start with light exercise. Begin with morning and evening walks, followed by a shower to remove sweat and cool your body down.

Consult with a doctor about treatment methods. Axillary hyperhidrosis is a condition characterized by excessive sweating in the underarms, and there are various treatment options that require consultation with a general practitioner. The first treatment option you may be recommended is the use of aluminum-based medications, but there are several other treatments available if the condition worsens.

• In some cases, oral anticholinergic medications like Rubinol may be recommended to help reduce sweating, particularly in the underarm area.
• Consider discussing onabotulinum toxin injections with your doctor. This is a non-surgical procedure that is effective, with effects lasting an average of 6 to 8 months.

Consider iontophoresis treatment. This is a type of electrical therapy, typically requiring 2 to 4 sessions, each lasting 20 minutes per week. Water is used to generate a small electric current on your skin, which may help reduce sweating for several weeks or months. Although results can vary and the treatment may be uncomfortable, it has proven effective in some cases.

Sympathectomy surgery should be viewed as a last resort. This procedure uses a small endoscopic tool inserted under the armpit to interrupt the sympathetic nerves responsible for sweating. While effective, it carries significant risks, including complications in respiratory function, nerve damage, and/or causing increased sweating in other areas of the body.

Consider Botox injections as a long-term solution. In theory, Botox injections have been used to control underarm sweating for up to six months and have been successful for some individuals. This method should only be considered if the underarm sweating issue is severe, as the treatment costs at least $700 and can be quite painful.

• No medical connection has been proven between Botox and sweating, and it is not widely recommended by the medical community as a therapeutic solution. However, some clinics still offer this treatment.
