Bad smells can give you nightmares

Attention all campers! You no longer have to bother dipping your bunkmate’s hand in warm water in an attempt to make him pee in the bed. If you want to know how to terrorize that kid who picked on you on the kickball field, all you have to do is get inside his dreams. Through his nose.

German researchers have found that sleepers exposed to an unpleasant smell will have negative dreams. The opposite is also true. When subjects were exposed to the smell of roses, their dreams were predominantly positive. These olfactory observers used rotten eggs in their study, but we are sure that a stinky gym sock, left perched on the pillow of your enemy, would work just as well. While we’re fairly certain that the researchers didn’t plan to have their findings used in this manner, there are always unintended (and sometimes dastardly) consequences of scientific breakthroughs.

Because our sense of smell involves such a sensitive and neurologically complex function, and because it’s so powerful in its influence on our behavior, it’s not surprising at all that so many scientists have studied the effect of different scents on emotion, memory, appetite, energy, and sexual arousal. The sense of smell is known to be closely linked to the same area of the brain which handles memory and behavior, which is why a familiar scent can trigger a vivid memory or feeling about the first time you got a whiff of it. Scientists have also found that our sense of smell intensifies when we sense a dangerous smell — such as a fire — sparking our brain’s fight-or-flight response.

It certainly seems logical that there would be a strong connection between smell and stimulation, but you might be shocked to find out what the most sexually “intoxicating” fragrances actually are.

To test the effect a scent has on arousal, Dr. Alan Hirsch, a nationally recognized smell and taste expert and the founder of the Smell & Taste Treatment and Research Foundation in Chicago, chose 30 pleasant odors and hypothesized that these enticing scents would stimulate more than just the nose. He measured penile blood flow while exposing men whose eyes were covered to various scents. The winner, by a nose, was lavender and pumpkin pie, with a 40 percent average increase in blood flow to the penis. The smell of doughnuts and black licorice came in a close second with a 31.5 percent increase in penile blood flow  Cranberry finished dead last, so you may want to leave that off the seduction menu.

Hirsch also studied the effect of odors on women and measured their sexual response. The winners: the combo of Good & Plenty candy and cucumber with a 13 percent increase in vaginal blood flow. Baby powder tied with a lucky 13 percent boost. Pumpkin pie and lavender also seemed to stimulate the ladies, coming in second at 11 percent.

Now, you’re probably ready to radically alter your choice of cologne and aftershave, right?  After all, who needs Chanel No. 5 or Boucheron pour Homme, when it’s apparently so much more provocative to slather a hunk of pumpkin pie across your neck or daub a melting Twizzler behind your ears? 

It’s said that humans are able to distinguish over 10,000 different odor molecules. We do this by simply breathing in. That whiff of air goes up the nostrils and makes its way to the roof of the nasal cavity where it hits a tiny area called the olfactory epithelium. The olfactory epithelium contains millions of olfactory receptor neurons.  On the surface of these neurons are odorant receptors that pass the smell information to the olfactory bulb (just underneath the front of your brain) and then on to the olfactory cortex in the temporal lobe of your brain.

Confused? Well, so are scientists. You see, humans have only about 400 odorant receptors on the surface of those sensory neurons. The otherwise humble mouse has approximately 1,200! Yet we olfactorily challenged humans can still detect thousands of odors.

Because the power of human sense of smell is so greatly underrated, the great and profound enigmas of scratching-and-sniffing remain to be solved.

I know that pleasant smells can put me in a good mood almost instantly. Here's a list of my favorite smells of summer:

coconut suntan oil
plastic floats in a pool
freshly cut grass
gasoline smell coming from the lawn mower in the garage
bar-b-que on the grill
asphalt being spread on a hot day
watermelon
the air right after a summer rain shower
hot dogs grilling outside
the air wafting out of the Dairy Queen window when you’re waiting for your cone
elephant ears frying at the fair
Band-aids
sweet corn when you’re shucking it
chlorinated pool water
smoky campfire
cherry popsicle
a baby after an Ivory Soap bath
lilac blossoms
a skunk from far away in the summer night air
onions and peppers grilling at the fair
honeysuckle flowers
ice cold root beer
Windex
Pez candy
Play-Doh
the metal smell of a roller coaster on your way up the first hill
fresh sawdust
brewing coffee
an apple pie baking in the afternoon
laundry after it dries on the line outside
It only makes sense.  I can smell somethings and be right back to a place I remember the smell being so vivid.
Informative article with a humorous twist. My favorite kind. I'll be thinking about dabbing that twizzler behind my ears ;-D
That explains why I am falling to my death every night my wife has gas.
I find this article fascinating.  And I certainly believe it--if we now use aromatherapy to heal people of sickness, why not believe that it affects many more areas of our life than we know.  I'm glad research is being done on this.

One confusion in the article:
When you say things like "pumpkin pie and lavender," or "Good & Plenty and cucumber," it's not clear if those were meant to be used TOGETHER to create an impact, or each one, on its own, creates the impact.
This makes a lot of sense.  Pumpkins pie for the holidays.  Think back.  Mom is in a pretty dress and bent over pulling the homemade pumpkin pie out of the oven for Thanksgiving.  Dad is standing in the doorway smiling as he thinks about how sexy her behind is even though he doesn't get to see it nearly as much as he would like.  The children standing next to dad with glazed looks are hoping they get the biggest piece of pumpkin pie.  Great memories that go from childhood to adulthood.  Love of food and love of sex.
THAT IS CRAZY HOW GOOD AND PLENTY GOT ON THE LIST....
I totally agree with these findings...because I was looking for an answer to sleeping better at night without a prescription.  I for one love the smell of Gucci for men and found if I spray a little in the bdrm upon retiring for the evening I feel calm and dream pleasant dreams. Another thing I have found was if the master bath door is left open and the seat is up on the toilet the odor from the chemicals interfere with sleep.
That's really aweomse!
The smell of cigar smoke, tar and gasoline can initiate a bad headache very quickly.  My doctor suggested keeping metholatum or coffee beans nearby to offset this problem and it has helped.
i think i smelt my bad breath the other night and gave myself a nightmare! what do you think??? i'm drawing this conclusion after i read the article.  what is your opinion?
love you
cassandra
nice info
it's worth it to try it out on my husband some night to see it some of these oders that you mentioned in your article will really work!  i am going to let you know if it works or not.

I'd like to know what sort of influence the smell of beer has on most men.  For my husband, it appears to be an aphrodisiac--and the more he drinks, the more aroused it seems to make him.  Too bad his nerve endings aren't functioning at that point, because he can't feel any blood flow ANYWHERE, let alone in his penis.  Sex at that point is an exercise in futility.
Please amplify your deep commentaries to the farting and involuntary noiseless mistakes that everybody commits in the multiple relationships of everyday human behaviour. Thanks.
Thats just great! i cant wait to go home and take a shower with my lavender scented body wash to get things going with my husband! who would have thought?!  =D
i have a partical plate and the top is metal, do you think it affects my taste, sometime i have no taste or smell kaye manns fieldale, va
I never knew that
wow! thankx for teaching me something!
I have such a heightened sense of smell that perfumes, scents, exhaust fumes, cigarette smoke always leads to instant headaches and sometimes migraines. I really wish people who wear strong scents would know what it's like to deal with this every moment of every day.
hmmmm...I wonder why cucumber for women??????
Most of this is plain common sense. When you go into molecules, etc. have your 101 chem book handy. There are more important factors that pertain to smell other than nightmares and/or ice cream flavors that I would be concerned about. For some of us we can distinguish between the different arrays of bacteria and viruses as well as "cancers" and their mutant varities. You might reference this to already known studies on the subject of "smell"/ and senses. Somebody should really pursue this area and make use of the research in a productive way!!!!
I had a dream, like where I was on this thing, and stuff, and it went that way. I really, really, really knew it. So I can see where the story is, and things.
Really, really cool!
So!!! Men have a better sense of smell than women!! We men also respond and react to smell more than women. So, All you ladies out there get your act together!!!Cook better dinners and use a better perfume.
That is so true!!Like I have to always have a clean house and smelling good and when its clean I'am happy!!! and when it stinks and is dirty I get in a really bad mood!!!! and its so true when I first met my boyfriend the cologne he was wearing reminds me of him and forever ill think of him when ever I smell it!!!@!!
I had a nightmare that I was walking through a toxic sewage dump only to awaken to my wife breathing foul breath directly into my face.
That's really weird.
Very interesting.  This summer I have spent alot of time at our travel trailer in the woods, and I am not sleeping well there.  Besides the woodsy smells, something else added to the mix.  We had wood rotting in the floor, which we had to repair, but there was a lot of moisture, and we could not remove everything, which added a musty smell.  (I have a mold allergy, so that's bad.)  But, a friend gave us a little jar of an odor eliminator that is used in hospitals.  It has a strong, very strong, soapy smell.  I find the fragrance quite offensive, but my husband likes it.  So, he put it in the tiny bathroom as an air freshner.  I close the jar every change I get because I hate the smell.  He opens it, even though I've voiced my objections.  Of course, in our tiny trailer the bathroom is in a corner with the bed on one side of the door, and the sofa/bed on the other side of the door, so you are always within about 5 feet of the odor.  I have been having crazy nightmares all summer.  And I am very restless.  Could it be that smell??  It all add up to YES!
Just in time for Thanksgiving! ;p
wow. that's pretty cool. i didn't know. now i understand a little more about dreams and what affects them. i wonder though, what kind of scent could trigger night terrors/tremors? let them experiment that, and publish the results. i'm sure the families with children that get those would be very relieved. i know i would be. :)
makes sense then that if you survive a lightening strike, you lose your sense of smell - the brain gets a bit fried and smelling takes up a lot of brain capacity.

and, despite the urban legend, we do use all our brain.
eeewwww gym socks..
well i would not doubt it, its like when you sleep with the TV on and you dream with the sound you hear and because the brain is  relaxed when your sleeping, and something like smells or  noises are near you ofcorse that would intrupt it,
i had a  lite candle once near my bed, and woke up in a good mood once, it was weird becase that day was a horrable day for me.
Wow! I have never knew that!! hehe O.O
yes i belive that if you smell something bad it could give you nightmares
Must be something to it;
I remember a few years ago, my now ex, burning a Rose fragrance stick and and realizing a little later, how relaxed I had become. It was sufficient for me to ask her to burn another one the following evening. Sadly it did not seem to work. Lavender is I understand worth putting on your pillow at night to aid/induce sleep. Worthy of further experiments.
WOW I never knew sense of smell could arose me or give me nightmares and pleasant dreams depending on the smell. That's good information to know. Maybe the next time I get a nightmare I'll reanalyze why I had the nightmare to see if any smells caused it.
Creating a romantic date around aromas and fragrances can be fun. I posted a creative date around this very subject not too long ago on mycreativedate.com.

If pumpkin is a positive sensual smell for both men and women, is there a supported peak in birth rate around 9 months after Thanksgiving?
Cool.
Are some humans cursed with too many olfactory sensors? If so, I must be one of them!
Everybody thinks I'm crazy but i really like skunk's smell!!! On the other hand prfumes, hair spray, deodorants, bleach gives me headaches. Am i normal?
Lol I'm gonna have to try that out. My boyfriend keeps having nightmares that he's at work (a cook) and can't get orders out faster than they're coming in. Maybe something that has nothing to do with food. Eucalyptis maybe?
What are the thirty pleasant odors?? Do men feel happy about different smells than women??  Will the smell of pine give you a pleasant dream about walking on a cool night through a well tended city park, a nightmare about being lost in the jungle, a weird image of some old car you were once in with a tree shaped deodorizer, or a memory of a long ago family Christmas???
This is some very good information i think that all kids should go to sleep with a good smell in their rooms
yay pumpkin pie!
Maybe thats why you always sleep better on freshly washed bedding; because, the smell of it is a refreshing and pleasant oder. hmmm i rather liked this story; thought it was very interesting.
this was a very interesting article. funny because when i bought a lavender body spray, my guy seemed to like it more ;)
that is so odd. ive read lavender turns men on before..so thats not new.  but the smells of aftershave turns me on as a women. if i guy smelt like pumpkin pie it would probably make me think he roled in poperi.or lavender i would think he has another women.
This article stinks! Ha! get it !?  . . .  nevermind . . .All I know is if I fart in bed it causes me to magically be thrown on the couch at night by my wife . . . .
