You Smell Like Outside

Posted by on May 21, 2010 in News, Technology

For years my family and I have discussed the oddity of the “outside” smell. I just thought this was a common thing. You go outside (especially on a windy day) and you come in smelling like “outside”. It’s kind of a musty, doggy, rankness that permeates you and gets in your clothes. This is especially true for kids and pets. They can run around outside for a few minutes and come in stinkin up the place.

I’ve always been aware of this smell, but then I gained a fondness for convertibles. Now, I cannot “drop-the-top” without infiltrating myself with this wondrous odor. I can walk in the door after the drive home and my wife promptly says, “You’ve been riding with the top down, haven’t you.” I started to think that there has to be a remedy to this stinky outside business, so I googled it. What I found was a complete lack of information about this. Apparently not everyone is experiencing it. Either it’s not happening in their area or their sniffer is immune to it. I found a few people asking similar questions on Yahoo! Answers, but the replies were very tedious.


Q. What is in the air that makes your clothes smell like outside?
A. Nothing. That is just sweat.

WRONG. This is not a body-odor smell. Besides I can walk onto my porch in 70 degree weather and do nothing for 5 minutes and obtain this odor.

A. It is physically impossible for the air to “have a smell”.

WRONG. Air/Wind can carry any number of odors. Ever been downwind of a hog-farm?

WARNING sidebar comment coming, but this is a peeve of mine. If you answer someone’s question on Yahoo! Answers or any other Q and A site, know the answer! It seems like everyone and their dogs answers these questions and do not know the answers. The point of these sites is to provide answers, not to sound important by making uninformed guesses. Sorry, I digress…

So I think I may have found the answer or at least part of it. Geosmin. I ran across this in a completely unrelated search, but the more I read about it the more I think it is the culprit. Geosmin is an odorous chemical mostly found in dirt. No one knows for sure, but it is thought to be the by-product of certain bacterias. The interesting thing is that the human smeller is particularly sensitive to geosmin. Very, very miniscule, microscopic portions of it can still be detected by our human noses. Here is another interesting thing: it can smell good in some situations and putrid in others. For example, ever walk into a freshly tilled garden and smell the fresh tilled dirt? That’s geosmin. Ever “smell rain” in the air? That’s geosmin. Ever encounter a “stinky” mud-hole? That’s also geosmin. Ever get a dirty taste in your tap water? Yes, even that is geosmin. It is considered a water pollutant in many areas of the country. My granddad used to say, “The lake must’ve turned over” when the tap-water tasted bad, but it must’ve been excess geosmin seeping into the water supply.

So, geosmin is very very small and can be carried on the wind and in the air. It maintains a dirty, musty smell and can settle into your clothing, hair, and even skin when you are exposed to it. Some regions have higher geosmin content than others and some people are not as sensitive to it’s smell. Hence the reason not everyone on Google or Yahoo! Answers knew what the question was about. Now I’m not 100% sure about this, but it makes logical sense that the mystical “outside” smell that has attacked kids, pets, and owners of convertible vehicles with it’s foul presence is a concentration of geosmin.

The downside is how to prevent it. Unfortunately, repelling geosmin is not easy. Engineers have worked hard on it due to the issue of it polluting water supplies, so I don’t expect to find a remedy soon. So for now I guess we’re stuck with “smelling like outside”. I’ll stock up on some Axe body spray and stash it in my glove box I guess. But if I walk by and leave a swath of a musty smell in my trail, just know that it’s not body odor. It’s just geosmin… well… or maybe just good Mexican food. 😉

  1. Thank you Carlos for good advise !
    Now what I do often at home when I open the windows is a spray with water and lavender essential oils ( a few drops ) . Smells fresh and clean !

    *** SOLUTION ALERT *** Hi, me again after my comment on Nov 5, 2019. Living in Canada I decided to continue my biking passion in the frigid weather thinking that “the outside smell” will go away since little to no bacteria should survive the freezing temperatures, right? …WRONG!!!

    Enough to say that the smell is stronger than ever…:-( so I did an experiment and found that hot steam will kill this odour. I bought an “ironing” steamer from a local store that I use on my jacket, gloves, hat and neck warmer after every ride…it works!!! I thought I should share this experience.

    Happy hiking, biking, driving…!

    Loved your bio and faith statement!
    Live in Missouri. Sometimes I have to wash my athletic jacket every time I wear it, even if its just going to the store – ugh! I expect the “smell” when I walk or garden. Some times of the year are worse than others. I was beginning to think something is wrong with my jacket! Other jackets don’t absorb odors as much. Thanks for your sharing your wisdom on smelling!

    Wow!!! Finally someone solve the mystery, I will show this to my wife who has lost her smell sense except for this Geosmin, which she can smell from kilometres away…thanks a lot David!!!

  5. Thanks a lot for solving the mystery behind that smell.
    I live on the coast of the Red Sea, in Saudi Arabia.
    I don’t know what a wet dog smells like, but to me that outside smell smells like “bird seed”.
    I hate it.

    So happy to find this! I live in the MD/VA/DC area and am plagued by this odor. To me, it smells like wet dog, but there’s also a metallic smell to it. I live in a townhouse and back in April/May, I decided to grow a couple of tomato plants in containers on my roof deck. They grew and produced tons of tomatoes, but I couldn’t eat them because to me, they tasted like that awful outdoor smell.

    I guess I have to learn to live with it, but at least I now know I’m not imagining it!

  7. So glad I’m not alone! Thank you so much for answering the question I could never answer myself 🙂

    Geosmin..lthat’s it…thanks for the name. Couldn’t remember it. Many thanks!

    It has nothing to do with you! Lots of people don’t not recognize it….but once you do….. WOW!! Within this blog something starting with a “c” is mentioned…I think that is the reason. I have experienced this all over the country. Two years ago I was sitting on our deck and took a drink from a shot glass. I poured another and there was that smell….on the glass. Asked my you smell this and she was repulsed. Same wet dog smell…off a glass. Since then she is well aware of it. Don’t change anything about your life…too many people have experienced it around the world.

  10. I have had this smell the last three weeks as soon as I walk outside my front door. I am glad I am not ctazy, because others said they could not smell it. I drink essentia alkaline water and I am wondering if this is what is causing the smell. I went to my pcp and dermatologist and neither knew what I was talking about. I am going to lay off the essentia water and my polyester dresses from amazon for a minute.

    Thank you for this blog.

  11. I have smelled this in the Caribbean, and all over the US. My wife never smelled it until I handed her a shot glass that I drank out of while sitting outside in the shade in northern PA…I said do you smell this and she was repulsed by it. From that time on she notice it all the time. Just a part of life that some people are lucky to be ignorant of. It have nothing to do with one’s hygiene.

    I’m from South Texas and I hate this outside ” wet puppy smell”. I was fascinated a few months ago when we spend a lot of time outdoors in Minnesota and there was no such odor on us! What’s the difference in the environment??

  13. Mari Rendon

    July 25, 2019

    Wow, this is great! I live in South Texas ( San Antonio/Boerne area), I have been saying for years,
    “You smell like the outside” whenever anyone walks in after being outside and my family would giggle. But then they started realizing what I was talking about. I can walk from inside any building, come right back in, within a minute or two and I smell. I’m so glad I’m not the only one that knows it’s “a thing”. And I knew water had the same smell but just never mentioned it. Thanks for sharing/posting this! 🙂

  14. I always found the smell here in America disgusting. Whenever we would go out and come back in we’d have this disgusting smell. Whenever I go home to the Middle East we never had this scent on our air there. For example, when we were kids in the Middle East, we would shower and go out and go outside and play and come inside and we’d still smell amazing. But I’ve realized in America, even if you Shower, the second you go out and come back in there would be a smell that wouldn’t leave. So you’d have to shower later on after you come back inside. This article was really interesting.

  15. I’m so glad I’ve came across this article to let me know I’m not alone. I’ve always smelled this on dogs and kids when they’ve come in from outside. But this is the third spring/summer in a row that I’ve started smell it on myself, from just being outside for a very brief moment. I was like what!, I thought this smell was for kids only. I have to keep body spray on me during the warmer months now.

  16. I’ve noticed if my hair is freshly washed and dried it’s much more likely to absorb this smell. Just standing on the porch for a few minutes is all it takes. If I wash & dry my hair early in the morning and don’t go out until late afternoon/evening, it’s much less noticeable in my hair.

    I grew up in Ohio, and it seemed to be common on the children who were extremely poor. Bratty kids at school called it the “poor smell”. Back then I kind of assumed it had to do with laundry/bathing. (Kids can be gross and not too bothered about cleanliness.) I very rarely smelled it on adults and never on myself or my family. Moved 500 miles south about 20 yrs ago and now I smell it on almost everyone. It’s awful and I don’t know if it’s just become more prevalent now or if there is something specific to this region. I’ve also noticed a very particular, almost sweet perfume smell here. In Ohio on warm days you could smell the sweet grass/plant sort of smell. This isn’t that, it’s almost artificial and occurs at all times of the year, even in cool or cloudy weather.

    I think I’m just cursed with a strong sense of smell. Hardly anyone notices either of these smells around me and most who do aren’t bothered by them.

  17. Illinois here and have smelled this my whole life. Absolutely true that many people can’t even smell it at all. I believe it is definitely the bacteria/Ph either on our skin or being let out through our pores that interact with other bacteria/Geosmin in the air.

    I’ve heard my whole life I have an amazing sense of smell, and if I try and drink a glass of water outside, the glass will quickly stink as another comment mentioned. The glass won’t smell by itself, only after I drink out of it. Anyone else get stinky drinking glasses outside?

    Thanks for this post David.

    This is bananas. I’ve always smelled this on others since I was little, and now smell it on little kids after they’ve played outside. I only recently as an adult started smelling it on my own hair after being outside for a few minutes and have been struggling with finding a new shampoo or something to help! Seems like there’s no real fix or answer, but it helps to know that I’m not crazy.

    I love it… sparkly LOL 🙂

    I live in Virginia and have always gotten this unfortunate smell when outside, but noticed most people do not. My brothers get it, and occasionally my husband, but not my mother or any other people I know. My husband and I call it smelling “sparkly” because the pungent, slightly metallic smell is initially so strong once I come indoors it makes me envision the smell actively jumping or popping around my skin, hair and clothes like tiny firecrackers. It calms down within a half hour or so, but doesn’t completely disappear. I only have to be outside for couple minutes, but when I come back in I smell “sparkly.” If I am around people I avoid any trips outside as much as possible.

  21. I did a bit research a few years back. It depends on what you mean by smell in the air vs your shirt and body smell like outside. I can’t speak for the smell in the air because it could be many things. For the smell you got from walking outside for even a short time, it is related to the bacteria on your body and shirts. The bacteria reacts to the heat, moisture, your body Ph and your body sweat when u are outside. Even though you don’t feel like u sweat u have added moisture to the skin enough for the bacteria to work.

    I tried a few thing that prolong the good smell. One use anti bacteria soap and it helps a bit. And I remember there are athletic detergent which helps your shirt smell also. I did it for a few months and gave up, it helps but if u are out there for a longer time, god helps u. U may need a shower.

    My wife doesn’t smell even when we walk for the same duration outside. I don’t know life is unfair but I learn to live with the smell. 🙁

  22. Glad I’m not the only one that was experiencing this! NY has always been humid but I started noticing this smell a lot within the past 2 years. Polyester and other synthetic fabrics trap the smell, I recommend switching over to cotton. I tested it and never smelled like “outside” when I wore cotton. It’s a hassle to have to check the clothing labels but it beats smelling like dirt/metallic aka “the outside smell”.

    It’s ozone. I actually have a machine that creates ozone (supposed to be healthy) and it smells the same, just on a stronger level. I hated it at first, but now it’s almost addictive.. I love when my kids hug me after playing outside because their hair is saturated in it. It’s also the “after the rain” smell you get, but mixed with dirt.

  24. This is a late comment to an old post about outside smell, but I’ve done a lot of reading. I think people who smell Geosmin have a sensitive sense of smell. My husband doesn’t smell it but I do. I life in Manhattan and after a 20 min walk home my baby stroller and blanket reeked of the ‘outside smell’. I sprayed the stroller with Lysol and hope it smells better in the morning. I take a change of clothes to work bc I don’t want to smell like outside. I have yet to figure out how to get rid of the scent but it does fade eventually unless my nose adjusted to it 🙁 hopelessly looking for a solution.

  25. I just want to comment that I nitice this smell on myself after I have been indoor tanning. The same exact wet dog, musty, outside smell. Not sweat or body odor. I think body chemistry and the way it reacts to UV rays might play a role

  26. This could also be people’s body chemistry. It’s stronger for some people than others, which is why you don’t necessarily smell it on everyone who walks out the house for 10mins and walk back in. In my opinion, those who has this strong smell afterwards are the same people whose perfume/cologne can last all day. It’s all a person’s body chemistry.

  27. its gotta be in us…….

    why dont cloths on the dry line smell like it?

    brainless opinion [ our bodies release some kind gas wen we get hot ? . ]

    anyone live where it’s just sand and no dirt? this has got me pissed off , I just showered and I went out side now I have to shower again..

    sharks piss out of their skin pores , maybe we release some kind of stink wen we get hot or when sunlight is on us? … facts .

  28. I notice this smell when I moved to San Antonio Texas . Then I moved in the hill country with many trees around and the smell is here too ! My solution for inside of the house ; I mist lavender water around the house . When I go outside I have a light sweater to use it and remove it as soon I get inside .

    I too have been smelling this smell even more since it has been cold outside. I like many don’t have to be outside for long and I smell it and it drives me crazy with the way it makes me and my youngest daughter smell. My husband and oldest daughter it doesn’t effect. I would have to agree that it is certain ph balances with the geosims. It makes me self conscience as to; do people think I stink when I am in the public? I can smell it on me; so can they?

    Thank you for this post.

    It’s even worse when you live on the ocean and go outside! Certain areas of our home smell when we open all the windows and doors. Cant locate the smell because it seems to move around. I thought it might be the mixture of dry inside air with moist outside air……. Smells like a wet dog!

    I LOVE this smell. It’s intoxicating.

  32. Hey guys! We just got a hight efficiency washer and dryer that requires high efficiency detergent. We used to smell after short stints in the outdoors and I was racking my brain to figure what, how and why. We noticed the difference right after we started using the new machines. My wife and I now actually keep our normal fresh smell throughout the day whether we venture outside or not. I believe that our outdoor smell problem has been defeated! 😀

  33. I’ve wondered the same thing. I don’t have that smell after going outside but my kids and husband do. Maybe it’s the Ph or hormones too?

    I do notice it more when it’s cold outside. It’s an earthy, musty, dank smell. I’ve talked to probably a dozen people about this phenomenon and no one has any idea what I’m talking about. So maybe it’s something in those of us who can smell it too and other people can’t?

  34. I am going with the gosmin theory. My wife never noticed it until I gave her a shot glass to smell. It was a summer’s day, in the shade and I had just used it. It had that pungent odour and she recoiled. No matter where in the world you are…that smell is there during hot weather.

    I have this issue as well but could it effect some and not others? My co-worker & I would go outside to smoke at the same time & when I return to the office I would smell up the place but not her. Even after taken a shower & standing outside for 10 mins with neighbors then go back inside & being the only one to smell like children playing outside. You know, that loud pungent smell. Some of my family members have this smell in fresh air but there are some who doesn’t. I wonder why, could it also have to do with our PH balance blending with Geosmin, or something similar?

    Ha Kate! I know exactly what you mean! I can get behind it for that reason too!

  37. I actually like this smell. It’s not so much that it’s a good smell as that it reminds me of the outdoors and playing outside as a kid.

    We moved to NW Minnesota from NJ about 2 years ago. Ever since, every single time my 3 kids come in from playing in our back yard they STINK! They smell exactly like wet dogs. It drives me crazy! The smell gets on them, in their clothing, hoodies, coats, hats, gloves, etc. I give them a bath and can still smell it on them. I never had this issue in NJ and it only seems to happen in our yard. I don’t smell wet dog outside but only on them when they come in the house. I keep looking for an explanation and this is the only thing I have come across that offers a possible explanation. So, thank you! I will absolutetly be looking into geosmin!!

    I hate that smell. Thanks for your input. I’m going to shower now!

  40. Im very thankful to read this article as i too, looked online but found not a single thing relevant. I too, was annoyed beyond belief at all those STUPID Yahoo answers!

    Now, the only thing is, i still wonder if this is what im smelling due to the facts thay I mainly notice it during hot weather, and it is definitely worse during the day.

    Another oddity: i do not have to go outside to smell it. If i shower before sleep, when i wake up the next day (especially if the weather is hot), i can already smell it on me! I believe this may because this building has so many cracks and crevices where putrid polluted outside air can get inside.

    Oh, if i go outside with a hat covering my head, my hair will remain fresh smelling, but my hat, clothes, and skin will not!

    Yup, i bet anything the smell varies by what city you live in. I live in los angeles county which is horribly overdeveloped. It’s virtually all cement and asphalt. No rain, high humidity, very dusty and smoggy air. Climate change has given us around 8 or 9 months of hot (88 to 122 degrees) weather, chemicals and other unnatural stuff are everywhere, and there are so many streets and cars literally everywhere, including one somewhat busy street just 2 feet from my bedroom window.

    All of these must be contributing factors.

  41. Try rubbing some talc, or just simply arrowroot powder (which is oderless and you can get at the grocery or health food store) before you go outside. Lotion does the trick too. These are my fixes. Doesn’t always last all day, but it helps!!

  42. OMG yes i smell this smell and all the women in my family smell it too. Even though it saves electricity and its better for the environment i can’t not dry cloths outside. i live in Arizona but i loathe that smell!!!

  43. Thank you!! Your pioneering work has solved an issue which has perplexed my family for decades!! LoL. We live in Virginia. My wife just told me this yesterday so I ended up here. Kudos!

  44. Thank you for your blog on this topic. I live in Delaware and have been perplexed about this phenomenon for years. It is especially bad In this area and/or I have one of those sensitive noses! My husband just steps outside momentarily and he has the wet dog smell until he hits the shower. AND he thinks I’m crazy because he doesn’t seem to smell it. It is frustrating simply because I feel like I need to shower every time I’ve been outside. I agree that polyester seems to really grab and retain the odor more than cotton.

  45. Thank you so much for this post. We thought we were the only ones in the world to be blessed with these unfortunate smelling powers.

    My wife and I are from the West coast and we moved to the Atlanta area 2 years ago when we discovered this smell. When either of us would walk to the mail box and back, we come back inside smelling intolerably to the other.

    We are hoping to find some sort of remedy to prevent or counteract the smell from ever being created. So far, the only way we’ve found to completely remove the odor is by changing our clothing. It’s a pain, especially after a short trip to the mailbox…but it’s better than the alternative.

    some times when I brush my teeth and go outside as soon as I brush to go to work I get a nasty wet dog smell in my mouth. I always think that its the water I rinse with but I think It must be the outside. Its freaking the nastiest taste and smell ever.

  47. I too am plagued with this terrible odor.

    Someone posted that they live in the chicagoland area, and I too live in that region.

    Its so bad… I can take a freshly laundered set of clothes, put them on, drive to work, and by the time I walk from my car to the front entrance, I can already smell the odor.

    It is beyond frustrating… and it almost chokes me it is so strong.
    It honestly makes me cough…

    Here are some facts:

    Many people have stated that this happens during the day or with sunlight… however this happens at night also.

    Not everyone can smell the smell.

    Polyester seems to attract it moreso than say… cotton or wool.

    Here is my speculation:

    Perhaps it is a type of bacteria, (maybe the wind blowing off the waters of a lake miles away?) which colonizes polyester very quickly. …and its growth is accelerated by sunlight, but is not hampered by the absence of sun.

    It honestly smells like polluted lake water, and I’m betting a nearby (several miles away) body of water is the culprit…… or maybe the lake has become a victim of the smell itself???

    I totally get it! I started to believe pollutants were the culprit after my oldest son moved from out home in the Baltimore/DC area of MD to FL (about 30 minutes inland, Gulf side). My 2 younger sons & I visited and I quickly noticed that my teen sons did not smell like “outside” even after walking 1/2 mile to the gym, playing basketball for hours, then walking back. They arrived without that “outside” smile, despite being drenched in sweat and walking in the FL Summer sunshine. I started to believe it was because the air quality was much better due to A LOT less traffic and being so close to the ocean.

  49. :: I just wanted to say I only get this smell when wearing white cotton shirts. It doesnt affect my dark colored shirts, so i never wear white cotton. Today I put on a new cotton shirt and went outside in the shade for 10 mins and when I came in I got the smell. I havent smelled it for years because I stopped wearing white cotton until today. It reminds me of wet dog and I hate it. I will never wear white shirts again. ::
