My younger son always sniffs in his snot instead of blowing his nose, and then he gets a fever. My MIL says it's because he's 'swallowing the infection'. Is it true, does sucking in mucus instead of blowing your nose cause fever?

Sucking in mucus repeatedly can sometimes push the infection deeper into your sinuses, which might worsen congestion. However, a fever is usually a sign of an active infection. It is best to consult a doctor if the fever persists.

I have to be very careful with my health and immunity due to my thyroid. If you are developing a fever, it is a sign your body is fighting something. Don't wait, get a doctor's consultation to check for any sinus infection.

Actually, my ENT doctor told me that sniffing back mucus can lead to sinus infections or middle ear pressure, but it doesn't directly create a fever. Fever only happens when your immune system is fighting off viruses or bacteria.

My grandmother always told us never to hold in a sneeze or sniff back phlegm because it traps the bad stuff inside. While that is traditional wisdom, please see a doctor if you are actually running a temperature.

I totally get it, when you have a bad cold, blowing your nose constantly is so irritating and exhausting. But try to gently blow it instead of sniffing back, as that can make your head feel very heavy and painful.
