Armpit odour is a common concern and nothing to be ashamed of. Almost everyone experiences it at some point, especially in hot weather, during stressful moments or after physical activity. While sweat itself does not smell, the odour develops when sweat mixes with bacteria on the skin. The good news is that armpit odour can be managed and, in many cases, significantly reduced with the right habits and care.
- Why armpits smell
The armpits contain a high concentration of sweat glands called apocrine glands. These glands release a thicker type of sweat that bacteria love to feed on. As bacteria break down the proteins in the sweat, unpleasant smells are produced. Factors such as hormones, diet, genetics and poor hygiene can make the smell stronger or more frequent.
- Improve your daily hygiene routine
Regular bathing is one of the most effective ways to control armpit odour. Washing your armpits at least once daily helps remove sweat and bacteria. Using an antibacterial or gentle cleansing soap can be particularly helpful. After bathing, ensure your armpits are completely dry before dressing, as moisture encourages bacterial growth.
- Choose the right deodorant or antiperspirant
Deodorants help mask or neutralise odour, while antiperspirants reduce sweating by temporarily blocking sweat glands. If odour is your main concern, a deodorant with antibacterial properties may be enough. If excessive sweating is the issue, an antiperspirant can help. For best results, apply antiperspirant at night when sweat glands are less active, and deodorant in the morning if needed.
- Watch what you eat
Certain foods can influence body odour. Spicy foods, garlic, onions and alcohol can make sweat smell stronger. Reducing these in your diet and increasing your intake of fresh fruits, vegetables and water can help keep body odour in check. Staying well hydrated also dilutes sweat, making it less likely to smell.
- Wear breathable clothing
Tight or synthetic fabrics can trap sweat and heat, creating the perfect environment for bacteria. Opt for loose-fitting clothes made from breathable materials like cotton or linen. Changing clothes regularly, especially after sweating, also helps prevent odour build-up.
- Remove or trim armpit hair
Armpit hair can trap sweat and bacteria, making odour worse. Shaving, waxing or trimming the hair can reduce the surface area where bacteria thrive. If you choose to shave, do so carefully and keep the area clean to avoid irritation.
- Try natural remedies
Some people find relief using natural options such as apple cider vinegar or lemon juice, which can help reduce bacteria due to their acidic properties. Baking soda can also help absorb moisture. Always test these remedies on a small area of skin first to avoid irritation.
When to seek medical advice
If armpit odour is severe, persistent or accompanied by excessive sweating, it may be a condition known as hyperhidrosis or bromhidrosis. In such cases, a doctor can recommend stronger treatments, medicated products or other medical options.
Armpit odour is a normal part of being human, but it does not have to affect your confidence or daily life. With good hygiene, the right products and a few lifestyle adjustments, you can keep odour under control and feel fresh throughout the day.
