There are a lot of illnesses that can cause loss or make your sense of smell less sensitive. Nasal congestion is one of the symptoms of illnesses that can affect your sense of smell. These include common colds, flu, hay fever, and at some point your smoking habits.
Another symptom is abnormal growths or nasal polyps which affect nerves inside the nose to make your sense of smell dull. How to regain sense of smell is a matter of treating the illness properly.
Head injuries impacting the nose can also affect your sense of smell. Much like illnesses, the nerves used to send signals to the brain may be damaged because of the trauma.
It is important to mention that losing your sense of smell affects your sense of taste. Your mouth is located just below your nose and it complements each other. The smells found in your food make it more appetizing aside from the taste that your tongue processes. Having a cold or blocked nasal cavity can make your food taste bland.
