Why Does the Bedroom Smells Bad After Sleeping?

How many times have you woken up feeling like your bedroom stinks?

It’s not uncommon to wake up in the morning and feel like your bedroom smells bad, especially if you sleep with your bedroom windows closed.

As much as it’s a common occurrence, it’s extremely unpleasant and off-putting because nobody wants to wake up in a smelly room! You may want to know why your room smells bad in the morning after sleeping.

Why Does Bedroom Smells Bad After Sleeping?

Many people are habitual of sleeping with the bedroom windows closed.

It gives them a sense of privacy and safety. But at the same time, it hinders the air circulation and makes the room smell bad.

If you’ve observed that your room smells really bad when you wake up some days, you may be eager to know what’s causing the odor.

The smell right after you wake up would surely annoy you, especially if you aren’t eating in your bedroom at night or doing anything that may make your room smell bad.

Well, it might not be because of something that you’re doing. There are several reasons why your bedroom might smell bad in the mornings.

We’ve listed down some possible reasons below so that you know why exactly your room smells like it does!

Body Odor

You might be asleep at night, but your body isn’t. The body continues to perform several regulatory functions.

One of the most important functions that continue round the clock (even when you’re asleep) is temperature regulation.

The body carries out numerous actions to ensure your body temperature is maintained at 37° C. The most significant is sweat production.

Sweating is a way through which the body releases heat from the body to ensure the metabolic and other activities that are going on inside the body at night don’t cause the body temperature to rise.

And sweat has got a distinctive odor because of the salts and skin bacteria that mix with sweat and make it stinky.

A person sleeps an average of 6 to 8 hours every night, which is quite a lot of time for the sweat to get soaked into the bed linens and clothes that you’re wearing.

If you sweat too much, the smell may dominate the air in your bedroom, which you’ll clearly notice when you wake up.

Another reason why your body may smell unpleasant after a long night’s sleep is the dead skin cells.

Your body works to naturally repair the damaged skin cells while you’re sleeping. The dead skin cells are shed off. These dead skin cells can make your body smell bad.

The smell of the dead skin cells can be strong enough to make your room smell bad in the morning.

Dirty Bed Linens

The sweat that your body produces at night when you’re sleeping gets soaked into your bed linen. The dead skin cells that are shed also fall onto the bed sheet.

This means that if you don’t change your bedding regularly, it’ll get saturated with sweat and dead skin cells and start to smell bad.

The smell of sweat and dead skin cell-laden bedding can be strong enough to make your bedroom smell unpleasant in the morning.

Even your pillowcases can be the reason for the foul smell in the morning.

The sweat and sebum from the scalp can make your pillowcases smell bad, which in turn can make your room smell bad.

Dirty Mattresses

A very common reason that we often overlook that may be the reason why your room smells bad every morning is your mattress.

All the sweat, oil, and dead skin cells that your body produces at night get soaked into the mattress. If you share your room with someone, it all gets multiplied by 2.

Since nobody washes or replaces their mattresses regularly, all of these bad-smelling agents accumulate in your mattress over several years and make your room smell bad all the time, not just in the mornings.

If you’ve got pets that laze around with you in your bed, the sweat and oils from their bodies may also get soaked into your mattress. Not to mention pet pee accidents!!

Dirty Laundry

A common practice that we’ve observed is people stacking their dirty clothes in their bedroom because they’re too tired by the end of the day to go all the way to their laundry room.

Remember that the clothes you wear all day are laden with sweat and oil from your body, and leaving them in your room means allowing the foul odor to dominate the air of your bedroom.

The worst (almost unbearable) odor comes from your used socks! People who go to the office wear socks all day long.

The feet are enclosed in the shoes, and there’s no way the smell from the sweaty feet gets to escape.

When you finally take your shoes off after coming home, the smell from dirty socks quickly spreads.


If you’ve got a pet, we’re sure you love cuddling them at night. While that sounds and feels adorable, it might be the reason why your bedroom smells so bad in the morning.

Nobody bathes their pets every day. Pets roll in mud and dirt and often have urine splashes and poop deposits on their fur. All of this is transferred to your bed when you let them in.

Even if you don’t let your pets get in your bed but prefer to have them sleep in your bedroom where you can keep an eye on them, the smell from their body is bound to make your bedroom smell bad.

Bad Breath

If your room is small and you sleep with windows closed, the chances that your bedroom will smell bad when you wake up in the morning are very high.

The air you exhale is mostly carbon dioxide.

When there’s a lack of adequate ventilation in your bedroom, carbon dioxide will accumulate and will make your room smell unpleasant in the morning.

Air that you exhale while you’re asleep smells foul. It’s natural so you don’t have to feel bad about it.

This foul-smelling breath dominates the air of the bedroom and makes your room smell the same.

Old Carpet

Your carpet may look clean, but it really isn’t, even if you vacuum every day. The fibers of a carpet are pretty big, and they can trap dust and dirt.

If you’ve ever spilled juice, tea, or milk on the carpet, part of it will get soaked in the carpet, no matter how swift you are at cleaning it.

All of these elements that your carpet is home to will lead to the growth of bacteria over time. And these bacteria will produce a foul smell that’ll make your bedroom smell really bad.


The foul smell in your bedroom every morning may be due to the growth of mold somewhere in your bedroom.

It’s not necessary that mold growth will always be visible.

Most of the time, mold grows in areas you don’t regularly check, like behind the drywall, inside the false ceiling, behind the bed, or somewhere inside your attached bathroom.

Mold has got a very distinctive foul smell. If the mold growth has spread across a large area, the chances that it’ll make your room smell foul are quite high.

If you can’t seem to identify what’s causing the foul smell in your bedroom in the morning (the bed linen is clean, the mattress has been cleaned, there are no pets, etc.), it most definitely is the mold!

Food Crumbs

If you’ve got the habit of eating food in your bedroom, you better be prepared to have your bedroom smell bad in the morning.

While eating, no matter how careful you are, you will drop a crumb or two in the bedroom. These food crumbs can be host to various microorganisms, insects, and even pests that make your room smell bad.

Also, you may have food crumbs under your bed or in spots that are missed during vacuuming. In this case, the food will go bad due to microbial action.

The smell coming from the deteriorating food can be very bad!

Poor Ventilation

You can prevent your bedroom from smelling bad if you’re careful about ensuring adequate ventilation in your bedroom.

Leaving the windows slightly open at night is one way to go about it. You can also install an exhaust system in your bedroom.

Poor ventilation is one of the primary reasons why the smell from various factors that we’ve listed above stays in your room. Had there been proper ventilation, the smell would have escaped.

Bedroom Smelling Bad After Sleeping What’s the Solution?

Air Fresheners and Scents

The reason why people are investing so much on scented candles and essential oil diffusers for their bedrooms is the fact that pleasant smells make you feel pleasant.

If your room smells good at night, you’ll sleep better. When you wake up in a pleasantly-smelling bedroom in the morning, your mood will automatically be improved.

Baking Soda and Other Solutions

Another effective solution is to use baking soda and other natural odor-fighters. These methods can neutralize and eliminate unpleasant smells completely:

  • Sprinkle baking soda on carpets or rugs, let it sit for a few hours or overnight, and then vacuum it up. This will help absorb persistent odors.
  • Clean bed linens, pillowcases, and your mattress using a mixture of water and white vinegar. This can remove bacteria, dirt, and oils that cause bad smells.
  • Place a bowl of activated charcoal in the room to absorb and neutralize odors. Replace it every few weeks for optimal results.

Relaxation and Bedroom Smells

Lastly, focusing on relaxation and bedroom organization may also help reduce bad odors after sleeping:

  • Ensure proper ventilation by keeping windows open during the day or using an air purifier with a HEPA-type filter to circulate clean air.
  • Clean and declutter your bedroom regularly to prevent accumulation of dust, dirt, and bacteria that can cause bad smells.
  • Place a few houseplants in the room to improve air quality and provide a calming atmosphere.

By simply following good hygiene practices and ensuring adequate ventilation in your bedroom, you can keep your room from smelling bad in the morning or any time of the day!

Frequently Asked Questions

Why is there a sour odor in my bedroom after sleeping?

A sour odor in your bedroom after sleeping can be caused by various factors such as sweat, saliva, and other bodily secretions that accumulate on your beddings and mattress.

These secretions can lead to the growth of bacteria and mold, which produce the unpleasant sour smell. To prevent the sour smell, you should regularly clean your beddings and maintain proper bedroom hygiene.

What causes a sweaty smell in my room after sleep?

The sweaty smell in your room after sleep is often due to body sweat produced during the night.

When you sleep, your body sweats to help regulate temperature, and this sweat often soaks into your bed linen and mattress. The damp environment can lead to the proliferation of bacteria, which can emit unpleasant odors.

How do body odors affect bedroom ambiance?

Body odors can negatively impact the overall ambiance of your bedroom. A room that smells unpleasant can make it difficult to relax, sleep, or feel comfortable.

In addition, lingering body odors can also become trapped in fabrics and furnishings, leading to a long-term problem with odor and cleanliness in your bedroom. Proper attention to personal hygiene and regular cleaning of linens can help minimize the impact of body odors.

What makes a bedroom smell like feet in the morning?

A bedroom that smells like feet in the morning could be due to dirty socks or shoes left in the room combined with poor ventilation.

Additionally, the smell might be attributable to damp conditions or too much moisture in the bedroom, which can encourage the growth of bacteria and mold. To combat this issue, ensure your bedroom is well-ventilated and avoid leaving dirty clothing or footwear in the room.

Could poor ventilation contribute to bad odors after sleeping?

Yes, poor ventilation can contribute to bad odors in your bedroom after a night’s rest. When your room is not adequately ventilated, the air becomes stale and trapped, making it difficult for odors to dissipate.

As a result, the smells generated by sweat, saliva, and other bodily secretions can linger in the room. To improve ventilation, be sure to open windows or use air purifiers when possible.

How is sleep-related odor different from nighttime odors?

Sleep-related odors primarily result from the natural processes that occur during sleep, such as sweating and shedding skin cells. These odors typically dissipate when you freshen your beddings and maintain good bedroom hygiene.

Nighttime odors, on the other hand, can encompass various non-sleep-related smells that might accumulate in your room during the evening, including cooking smells, pet odors, or outside pollutants.

Addressing nighttime odors may require more thorough cleaning and identifying the specific source of the smell.
