Pregnancy can be really challenging when all of a sudden your sense of smell seems to be supercharged. For many people, super-smell is one of the first symptoms that they notice in their first trimester. When I was pregnant with my first child, I had an immediate reaction if anyone in my midwife’s waiting room was wearing perfume. YUCK! All of a sudden my husband smelled like he was a bathing in sausage water and walking into our pantry would instantly make me run to the sink. When my husband brought me a beautiful bouquet of stargazer lilies that I used to LOVE, I couldn’t even walk into the house with them there. Your sense of smell makes a huge difference in what you eat and how well you can keep the contents of your stomach inside of you too.
Why??
I found this article that reviewed all the scientific evidence about pregnancy and the sense of smell. What we know from science is that most people (90%) report having a sudden repulsion to certain smells, while only 10% find any smells better than when they weren’t pregnant. There are several theories as to why, the leading one which seems to be that it possibly helps you avoid toxins to protect the growing baby inside of you. They even gave people pregnancy hormones to try to see if it was hormonally related, and the results weren’t very conclusive. Another study summarized there didn’t find any heightened sense of smell in their participants between first trimester and postpartum. The author of course also adamantly notes that an abundance of anecdotal evidence exists to support increased olfactory senses during pregnancy, and suggests further research into the phenomenon. There are plenty of other theories, but no true abundance of evidence points to one simple explanation why 2/3 of people report super-smellers during pregnancy.
What Can You Do?
Stink happens, but how can you really deal with ALL the smells that make you want to hold your nose? I personally took a page out of the Victorian era playbook: I kept something good smelling in my pocket. This could be a favorite lip balm, a handkerchief with some essential oils on it, or even a vapor inhaler if that menthol smell is still appealing to you. Wearing a tight fitting N95 mask is another option that we should all be familiar with now too. I knew one friend who suffered so much with Hyperemesis Gravidarum that she actually kept alcohol wipes in her pocket in case a wave of nausea overtook her. Trying to keep track of all the smells that are terrible isn’t honestly worth your time though, because they could change and you’re sure to encounter some unexpectedly. Be prepared, and don’t be shy about keeping emesis bags in your car and purse in case you need them. Maybe your super sniffer would feel better going to somewhere that will 100% smell good, like a spa?
Rest assured, most people report that their super sniffer skills fade when they aren’t pregnant anymore. I promise you that my husband doesn’t still smell like he’s sweating sausage water and grandma perfume doesn’t make me instantly hurl anymore. Some aversions might stick with you, like I still can’t smell stargazer lilies, despite the fact that I really do think they are beautiful. I also can’t eat saltines anymore, but that has nothing to do with smell and more to do with the memory associated with eating far too many in my first trimester. You may be too busy changing diapers to even notice when your sense of smell goes back to normal, but you will 100% appreciate that fact when your baby starts eating solids and their poo changes smells again.
