Homeowners who sleep with their windows closed may wake up to a musty or bad smell in the morning. This musty and bad smell in the morning is caused by multiple things.
Bedrooms smell bad in the morning due to bad breath, body odor from sweating throughout the night, and infrequent changing of sheets or pillowcases. This leaves a bad smell that remains in the stagnant air.
This is common among homeowners who have smaller bedrooms, where the air circulation is poor. We’re going to break down the many reasons why there is a musty smell in the bedroom and what you can do to prevent the smell.
Why Do Bedrooms Smell Bad In The Morning?
Mold Or Mildew
One of the main reasons bedrooms may smell bad in the morning is the mold or mildew that may be growing behind your walls.
If you’re someone who spills a lot of drinks, be sure to check in any of the dark places near where you’ve spilled your drinks. Wet, dark areas are the breeding ground for mold and mildew. We also recommend checking in closets or behind walls if any mold is growing.
This could be caused by pipes leaking, and mold can grow over time.
If your bedroom is in a smaller room, big enough to fit a queen bed, a dresser, and a nightstand, the CO2 that you breathe will circulate the room as you’re sleeping. A combination of the bedroom door being closed, along with the windows being closed, will cause the CO2 (which comes from your breath) to remain in the room longer.
Naturally, our breath overnight is grungy and isn’t pleasant to the smell. Circulating this bad breath throughout a bedroom is one cause of the musty smell in the morning. The bad smell is trapped in the room until the morning when it’s released into the hallway when the door is open.
To release this smell, crack a window, or leave a door open so the air can circulate properly throughout the bedroom.
When we sleep, our bodies naturally repair damaged skin and try to regulate itself back to normality. What’s leftover from this process is often dead skin cells, natural oils the body secretes, and a light sweat that the body gives off trying to regulate body temperature.
In the process of regulating body temperature and producing sweat, the unfortunate results are body odor. Body odor is the byproduct of sweat over a long period of time. Because our body is sleeping for 6-8 hours, there’s nothing we can do about the body odor smell.
Consistently sweating and building up bacteria will give off a musty smell in the bedroom if nothing is done with the bedroom sheets or mattress.
Dirty Sheets & Pillows
Due to the high volume of sweating, especially during the summer nights with no air conditioning or bundled up in a dozen blankets.
We refer to dirty sheets as bed sheets that haven’t been cleaned in 2 weeks or more. Cleaning bed sheets is a large part of eliminating bad odor and musty smells from your bedroom.
Along with the bedsheets, our pillowcase is another catch-all for oils and dead skin. Frequently washing the pillowcase and bed sheets together are essential to keeping a room smelling fresh.
Another known source for musty smell is the mattress. It’s hard to throw away a mattress, especially if the person sleeping on it is getting quality sleep. Mattresses absorb sweat and oils as well, but unfortunately, you’re unable to wash an entire mattress.
If you’ve had your mattress for over 5 years, it’s safe to assume there are 5 years worth of sweat, oils, and dead skin accumulating on the surface and within the mattress. If two people are sleeping in the bed, there’s double the amount of sweat, oils, and dead skin in the mattress as well.
Filthy Floor Or Carpet
If your sheet-cleaning habits are relatively clean, the next item to look at is the carpet. If you don’t have a carpet, feel free to skip the next section.
Carpets accumulate dirt, dust, and bacteria from clothes over time. Even a well-kept and clean rug can have some flaws. Often when we vacuum, we miss spots near or under the bed. The dirty carpet will start to give off an odor, leading to bad smells in the bedroom.
It’s in your best interest to get a new rug every 6-8 years to maintain freshness in the bedroom and fight the musty smell.
Dirty Clothes On The Ground Or Hamper
The next and probably most obvious smell is the dirty or sweaty clothes kept in the room. If you work an outdoor job, there’s a good chance that leaving clothes in a dirty hamper will start to leave a musty smell.
Consistently washing and removing dirty smells from the bedroom will eliminate any build-up of a musty odor, especially if you like to sleep with your door and window closed.
We recommend removing work clothes from the bedroom immediately after work to eliminate musty smells from accumulating.
Food Or Drink Spills
Our last option and another common reason for bedrooms to have musty smells is leftover food and drink.
If you like to eat food in your bedroom, whether it be on the desk or your bed, crumbs and food smells can start to accumulate. To eradicate this odor, we recommend checking under your bed, as well as the mattress, to see if any food has spilled under.
Often the smallest of crumbs will accumulate and give off a foul odor. We recommend never eating in the bed and having a small desk or something to eat if you must eat in the bedroom.
Pets Or Animals
Pets and animals can also be a reason for a musty smell in the bedroom. If a cat, dog, or even a mouse has gone to the bathroom in your bedroom, you must locate and clean it as soon as possible.
Urine that is leftover time will develop a musty smell that is hard to get rid of, especially if the room’s windows and doors are consistently closed.
Homeowners who allow pets to sleep on their bed remember that the dog or cat may have been rolling around in dirt, mud, or even poop all day long. They bring that dirtiness to your bed as your body tries to rest and recover. It may be in your best interest to have the dog sleep on the floor or outside the bedroom while you rest and recover.
Ways To Eliminate Smells From Your Bedroom
Here is a list of air fresheners that you can use to eliminate the musty smells. These fresheners will help eliminate the dirty bedroom smell that you get in the morning.
Fresh air helps bring in a fresh aroma into the room. Rooms that are consistently closed trap and circulate the dirty air that remains in the room.
We recommend cleaning your room and letting the windows open for 10-15 minutes a day to circulate fresh air into the room. This will help get rid of the musty smells.
If musty smells persist and you’ve done all you can to change the sheets, we recommend purchasing an air freshener. These fresheners are small, cheap, and leave the room smelling good as new.
Our pick for air fresheners is Air Wick’s Plugin Scented Oils. These can be found here on Amazon for a relatively low price.
The Air Wick combination pack comes with 2 warmers that plug directly into the wall along with the air fresheners.
If you’re looking for a simpler solution that doesn’t require power, gel beads are a great alternative.
This two-pack of gel beads is perfect for eliminating musty smells and leaving your bedroom smelling fresh every morning.
Made by Clear Air, their odor neutralizing gel beads are great for any room in the house. Place the container on your nightstand or bureau and let the gel beads illuminate your room with clean air.
If you have a musty smell in your room, the first order of action is to get clean air flowing. Open a window or a door to see if that fixes the issue.
If the musty smell still prevails, washing the sheets, pillowcase, or getting a new mattress would be the next action item to remove the smell.
Next, we recommend checking the carpet or rug for any lingering smells. Make sure there’s no food or drinks leftover underneath or next to the bed.
Last, check for any dog residue or bathroom droppings to ensure there’s no smell. If the smell persists, try sleeping with the animal outside of the bedroom for a few nights and see if it makes a difference.
Bedrooms should be clean, as it’s the place for our bodies to rest, recover, and restore health.
