What is an allergy and how does medicine help against it?
In: Biology
When you get a cold, usually that means a runny nose. There’s an infection in there! And the immune system response, among other things, causes the runny nose.
Sometimes there’s no infection, but because something got in there (like pollen or dog hair), the immune system THINKS it’s an infection, so you still get the runny nose.
The medicines that help, they are medicines that tell the immune system to relax and calm down, or they are medicines to tell the nose to stop being so runny.
