3. Antihistamines Don’t Have an Effect
This one is quite obvious, but it’s still worth mentioning. Antihistamines are supposed to stop the production of histamines, which in turn cause allergies due to a glitch in the immune system. The histamines misinterpret pollen or dust as harmful bacteria, and they send signals to the brain to flush the foreign substances out. Antihistamines stop these signals, which in turn stop the sneezing or the runny nose. If taking antihistamines doesn’t do anything to alleviate the pain, then obviously it’s not allergies.
