Insect stings usually produce only local irritation and discomfort. However, for an unlucky few, about 1% of us injected with insect venom during a sting can have more serious consequences. Reactions can range from a large local reaction to death due to an allergy to the venom.
Nose, Sinuses, and Ears
We all take for granted that breathing through the nose is normal for everyone. However, there are several million people who do not have the luxury of breathing through their nose. When we breathe through the nose, the air circulates through the sinuses and while passing through the sinuses the air is humidified, filtered, and brought to body temperature.
