Understanding What Causes an Allergic Reaction

Last updated 4 years ago

Allergies are a curious thing. It’s strange to think that natural substances can make some people break out in hives while others remain completely unfazed. If you suffer from allergies, you might be curious as to why your body reacts negatively to otherwise harmless substances.

Your body’s immune system is programmed to protect you from a wide range of pathogens. However, your immune system may mistake certain harmless substances as threatening viruses or bacteria, and sound the alarm when exposed to said harmless substances. No one is exactly sure what causes the body to mistake allergens for harmful pathogens, but allergic reactions can cause serious discomfort and even death. It’s important to be very careful about allergic reactions, as what may seem like a mild allergy initially may turn out to be a severe allergy after repeated exposure.
