A doctor has shared an affordable item available in most supermarkets that could help combat smelly armpits. While sweating is a natural bodily function, it can lead to unpleasant odours. The armpits contain millions of sweat glands, including eccrine and apocrine glands, which can produce odours when stimulated by various factors. London-based GP Dr Sermed Mezher explained that bacteria on the skin can convert sweat molecules into pungent compounds, causing the odour. Antiperspirants are commonly used to reduce bacterial growth and odour; however, for those seeking additional protection or finding antiperspirants ineffective, iodised salt could be an alternative.
Dr Mezher suggested that iodised salt, such as a 400g bottle of Cerebos Iodised Salt priced at £1.50 from Sainsbury’s, mixed with water and applied under the armpits, could help by killing bacteria temporarily. Iodine in the salt is known for its antiseptic properties, potentially reducing underarm odour. Some believe that salt may form a protective barrier against odour-causing bacteria, but others caution that it could irritate the skin and may not be effective for everyone. Dr Mezher emphasized that while this method may help with odour, it does not prevent sweating. For those dealing with excessive sweat, consulting a healthcare professional is recommended.
Aside from iodised salt, Dr Mezher suggested benzoyl peroxide for those aiming to eliminate sweaty armpits entirely. Excessive sweating could be a sign of hyperhidrosis, a common condition for which over-the-counter solutions like stronger antiperspirants, armpit or sweat shields, foot powders, and soap substitutes are available. It’s essential to seek medical advice before making significant lifestyle changes. Iodine, found in iodised salt, is a vital nutrient contributing to various bodily functions like thyroid health and cognitive function. While some foods are good sources of iodine, adding iodised salt may enhance its intake and potential benefits.
