Reasons for body odor and characteristics of symptoms What is body odor (specifically underarm odor)? Self-check its characteristics and the severity of symptoms. Body odor, or "axillary osmidrosis," is a condition characterized by the production of sweat with a strong odor. It is seen in approximately 10% of Japanese people, and those with the following characteristics are more likely to have body odor (bromhidrosis). When I sweat under my arms, it emits a strong odor like sulfur or onions. The earwax is moist and soft. When you sweat, yellow stains appear on your clothes. I have a relatively large amount of underarm hair. Furthermore, underarm odor can be classified into three stages—mild, moderate, and severe—depending on the intensity and nature of the smell. The degree of body odor Features Mild Often, only the person themselves is concerned about the smell, and those around them don't notice.It's something that can be managed with self-care. Moderate A condition where the odor is noticeable in crowded spaces or when there are people nearby.It's also a good idea to consider treatment in addition to self-care. severe The odor is noticeable even to people in the same space or those wearing thick clothing.While practicing self-care, it is recommended to consider prompt medical treatment. Knowing how your symptoms fit into the given categories will help you take the right steps to address underarm odor. Reasons why body odor occurs The cause of body odor (specifically underarm odor) is sweat from a type of sweat gland called the "apocrine gland." The human body has two types of sweat glands: "eccrine glands" that circulate throughout the body, and "apocrine glands" that are located in specific areas such as the armpits and groin. Sweat from eccrine glands is thin and watery, and since it is mainly composed of water and minerals, it has almost no odor.On the other hand, the apocrine glands secrete sticky sweat. This sweat contains various substances such as proteins, sugars, and ammonia, and when bacteria present in the armpits break it down, it emits the strong odor characteristic of body odor. Characteristics of people prone to body odor Body odor, specifically underarm odor (bromhidrosis), is more common in people with a large number of apocrine glands, regardless of gender. The number of apocrine glands is influenced by genetic predisposition, so people with a family history of underarm odor are more likely to develop the condition.Aside from genetics, daily dietary habits play a role. Lipids found in meat, fried foods, and dairy products are excreted through the apocrine glands as sweat, causing a strong odor. Those who frequently consume high-calorie, oily foods should be careful. Can hair removal help improve body odor? What's the relationship? The relationship between body odor and hair removal, part 1: Hair removal makes the skin more hygienic. The reason why hair removal is considered effective in improving underarm odor is that it makes it easier to keep the skin clean. When underarm hair grows, the skin becomes damp when you sweat, which promotes the proliferation of resident bacteria. When resident bacteria increase, they tend to produce a strong odor, and the symptoms of underarm odor appear.When you remove underarm hair and reduce the amount of hair, your underarms become less prone to dampness even when you sweat, making it easier to keep them hygienic. Because the number of resident bacteria also decreases, the strong odor characteristic of body odor tends to diminish. The relationship between body odor and hair removal, part 2: Hair removal may weaken the function of sweat glands. The characteristics of the hair removal treatment methods are one of the reasons why they can be expected to be effective in improving underarm odor. As shown in the following table, there are several hair removal treatment methods. Places where you can receive it Treatment method Features Beauty salon Light-based hair removal (flash hair removal) This method uses light to slow down hair growth through heat. Beauty clinic Laser hair removal (medical hair removal) This method involves using a concentrated laser to destroy the hair-producing tissue through heat. Beauty clinic Needle hair removal This method involves using a needle to apply a small electric current to the hair follicle, destroying the tissue that produces hair. The hair follicles from which underarm hair grows and the apocrine glands that produce sweat causing body odor are located very close together. When hair removal methods such as lasers or needles are used to target the hair-producing tissue, the heat or electric current can sometimes be transmitted to the nearby apocrine glands.While there are significant individual differences depending on the severity of body odor and individual constitution, this can potentially weaken the function of the apocrine glands, reduce sweating, and decrease the odor of body odor. The relationship between body odor and hair removal, part 3: Reduced self-treatment leads to less skin irritation. One reason why hair removal is effective in improving underarm odor is that it reduces the burden of self-treatment. Self-treatment of underarm hair with razors or tweezers can damage the skin.Skin damage from self-treatment can also stimulate the apocrine glands located near the hair follicles. This extra stimulation can increase sweat production, making you more prone to body odor. Reducing hair growth through hair removal eliminates the need for underarm hair care, thus reducing the likelihood of developing body odor. Types of people for whom hair removal is suitable as a countermeasure against body odor Hair removal does not fundamentally cure body odor! Hair removal does not "cure" body odor (specifically underarm odor). It simply reduces the amount of underarm hair, making it easier to maintain clean skin and potentially reducing the odor. Those seeking a fundamental improvement in underarm odor will need surgical treatment at a clinic. However, some people experience a significant reduction in underarm odor through hair removal, while others do not. Let's take a closer look at the reasons for this difference. Who are the people for whom hair removal is likely to reduce the symptoms of body odor (specifically underarm odor)? I have relatively little underarm hair. People with less underarm hair may find that hair removal reduces the symptoms of body odor more easily. Apocrine glands are located near hair follicles, so people with fewer hair follicles tend to have fewer apocrine glands.Since a smaller number of apocrine glands often results in milder underarm odor symptoms, hair removal can be considered a way to keep the underarms clean, which can help manage underarm odor. Mild symptoms of body odor Even those with mild underarm odor symptoms can benefit from hair removal, as it can reduce the odor. Hair removal makes it easier to maintain good skin hygiene, simplifying daily grooming.If you have mild underarm odor, you are less likely to suffer from a strong smell if you practice proper sweat care on a regular basis. It's important to prioritize self-care to prevent symptoms and odor from worsening. Who are the people for whom hair removal is less likely to reduce underarm odor symptoms? I have a lot of underarm hair. For those with a lot of underarm hair, hair removal often doesn't effectively address underarm odor. Having thick hair doesn't necessarily mean that 100% of people have underarm odor.However, a large amount of underarm hair means a large number of hair follicles, and it's possible that there are also many apocrine glands in the underarms. It's recommended to consider measures other than hair removal, such as reviewing your daily care routine. The symptoms of body odor are very noticeable, and the smell is strong. Even in individuals with moderate to severe underarm odor, hair removal tends to be ineffective in reducing the smell. When the odor is noticeable to those around the person experiencing it, simply removing hair and keeping the skin clean is often insufficient to completely improve the situation.If you are constantly troubled by strong body odor, it's recommended to thoroughly practice self-care on a daily basis and also consult a clinic or other medical professional. Effective ways to combat underarm odor! 5 recommended methods for improvement Body Odor Prevention Tip 1: Wipe away sweat frequently. The most important thing in daily efforts to prevent underarm odor is to keep your armpits clean. If you leave sweat on your armpits, they become damp, and bacteria break down the sweat, causing a strong odor.After sweating, be sure to wipe it away frequently with a towel and don't leave it lying around. Sweat-soaked underwear and clothes can also cause unpleasant odors if left unattended. It's a good idea to have a change of clothes ready, and to choose clothes made of breathable natural materials such as cotton or linen whenever possible. Body Odor Prevention 2 | Regularly remove underarm hair Maintaining well-groomed underarms to prevent dampness and sweating is also a recommended method for combating body odor. Shaving with a razor can damage the skin's surface along with the hair. Use an electric shaver, which is gentler on the skin, and shave in the direction of hair growth.Also, since skin becomes very dry after self-hair removal, it's important to moisturize. Even a skincare lotion will do, so be sure to moisturize thoroughly after self-hair removal. Body Odor Control Method 3: Use deodorants and antiperspirants For everyday, easy ways to combat underarm odor, it's also recommended to use deodorants and antiperspirants. While these two may seem similar, they have different roles, as follows: deodorant It prevents bacteria from multiplying and suppresses sweat odor. antiperspirant A product that temporarily reduces the amount of sweat. If you are particularly concerned about underarm odor, try using a deodorant product that can suppress sweat odor. Some antiperspirants also contain antibacterial ingredients, so it's a good idea to check before purchasing.However, applying too much of either product can clog pores and lead to skin problems. Always wipe away underarm sweat and cleanse the area before use, and be careful not to apply too much. Here are our recommended deodorant items. Body Odor Prevention Tip 4: Reconsider How You Wash Your Underarms Washing your underarms correctly can also help prevent body odor. Even if you think you're washing them carefully, areas with hollows or ridges in the underarm area may not be completely clean of sweat and dirt. Lather up your body soap well and gently wash your underarms with plenty of foam.Scrubbing vigorously with a towel or your hands is strictly prohibited. This can strip away essential oils from your skin, leading to dryness, which in turn causes excessive oil production and creates a vicious cycle that worsens body odor. Body Odor Prevention Tip 5: Improve Your Diet Maintaining a well-balanced diet is also important. While body odor is deeply related to genetic predisposition, people who eat a lot of foods that make the body more "acidic," such as meat and fried foods, tend to be more prone to developing body odor.Be careful not to overeat foods high in fat, and try to incorporate a balanced diet with various nutrients. Adding alkaline foods to neutralize a body that has become acidic, or foods like pickled plums and vinegar, is also recommended. Let's take the right measures to deal with the odor and symptoms of underarm odor. Body odor (specifically underarm odor) is caused by genetics, but it's very difficult for anyone, male or female, to simply accept it as "unavoidable." Because it's such a delicate issue, it's important to have the correct knowledge about daily care and its connection to hair removal.
