How do you block smells from your nose?

To block smells from your nose, you can try pinching your nostrils shut or breathing through your mouth instead. Using a mask or respirator can also help filter out odors. Additionally, applying a small amount of menthol or essential oils like peppermint to your upper lip can distract your sense of smell. Lastly, staying in a well-ventilated area can help reduce the intensity of unpleasant odors.
