You can apply strong fragrances to prevent body odour but you have to know the reasons why you sweat so much and why your body stinks.
Sources of body odour:
Poor diet: Lack of nutritious foods in the diet leads to body odour. If you have food that is too oily and spicy, you can get strong body odour. Red meat, spices and garlic are few foods that leads to pungent body odour. Include Vitamins and mineral rich foods in your diet to prevent body odour.
Blood sugar: Ketone substance in the body makes you know that you are from blood sugar. Ketones smell like a fruit and often comes from the mouth. You might feel that the fruity smell is good but, actually it is a pungent mouth odour. It is very important to control this body odour or you might suffer from severe health problems. Consult your doctor and control blood sugar levels.
Hairy armpits: Armpits have hair. If you do not clean the armpits, you end up spreading pungent body odour. Armpits have a large amount of apocrine glands (sweat glands) that produce sweat. You can try different methods to remove unwanted hair from your body parts like armpits. Waxing, shaving and hair removal creams are common methods to remove unwanted hair from the body. Wash your armpit regularly to kill bacteria and fight body odour. Use an anti-bacterial soap every time.
Hypertension: Getting tensed due to small or major issues leads to body odour. This is one of the most common sources of body odour. When you are tensed or stressed, you sweat more. Your palms, feet and body starts secreting sweat and this makes you smell pungent. When you are tensed or under stress, your body secretes cortisol (a stress hormone). Cortisol helps you fight anxiety but it also increases the production of sweat.
Digestion: Fecal body odour or urine body odour is a common problem that you can face if you have a slow digestive system. Constipation and gastric problems increase body odour. Too much of fibre rich foods causes smelly gas and lack of fibre in diet leads to constipation. When you suffer from digestive problems, the body secretes toxins that lead to urine odour.
These are few sources of body odour. To prevent spreading pungent smell all around you, watch out what you eat. Maintain hygiene and see that you wear fresh and clean clothes regularly.
