Household cleaners can be a risk factor because the odor of the chemicals will not be noticed to warn the person that the chemicals are toxic and should be used in a well- ventilated area. Warning labels should be read as a reminder of the chemicals involved in such things as hair products, bathroom and kitchen cleaners, insecticides, etc. Our sense of smell keeps people aware of automotive troubles. Regular checkups should occur to prevent problems. The sense of smell is also very important in detecting spoiled food.
Some people are more likely to have olfactory deficits.
People, ages 65 and over, commonly experience progressive impairment in both taste and smell. The proportion and population of the elderly is constantly increasing and they are experiencing age related sensory loss. The most publicized sensory loss of the elderly has been sight and hearing. There has not been much attention or research done regarding the loss of smell. The main cause of olfactory loss is normal aging.
