chosen: As people age, their sweat glands, skin and immune systems stop working as effectively, leading to an increase in body odour. Additionally, the hair and oil glands of the scalp become less active, which can also cause noticeable odour. The accumulation of germs on the skin due to inefficient immune function is another factor that leads to an unpleasant smell. Poor dental hygiene and a weaker circulatory system can also cause an unpleasant body odour.
