What does it mean when you smell bad?

When you smell bad, it typically indicates the presence of odor-causing bacteria on your skin or in your body, often due to sweat, poor hygiene, or certain foods. It can also be a sign of underlying health issues, such as infections or metabolic disorders. Additionally, factors like clothing materials and environmental conditions can contribute to body odor. Maintaining good hygiene and addressing any health concerns can help mitigate unpleasant smells.
