Where Does the Sweat Smell Come from?

Many people face this problem, and you must try to identify and sort out the main causes of this funky smell.

Breathing is as essential to mattresses as it is to human beings. After throwing your sheets in the wash, open the windows and let your mattress breathe. You can do it before putting on new sheets.

It needs time to air out because your mattress doesn’t have the opportunity for air to circulate and freshen up naturally. But when your windows are open, it naturally deodorizes the mattress.

Sweat Smell from mattress

Your sleeping Environment

Everyone enjoys a comfortable sleeping space. However, there can occasionally be a delicate line between comfort and overheating. Unbreathable bedding, clothing, or even a mattress causes night sweats. Your sleeping environment can be the leading cause of sweat smell, so make sure to clean and freshen your environment.

Bodily Fluids

Millions of microscopic bacteria, viruses, and fungi live on our skin. These microorganisms are generally harmless, but when combined with our sweat, they produce a stench.

Some people produce mustier odors than others, especially those who sweat more frequently. One of the main reasons your mattress has started to smell is that you tend to sleep hot and often get night sweats.

Another common source of unpleasant mattress odors is urine, particularly for households with pets and small children.

Stuck Moisture

Some mattresses are more likely to retain moisture, such as memory foam mattresses that adhere to the contour of their users’ bodies. Unattended moisture buildup can promote mold and mildew development, producing unpleasant aromas. Pungent, musty smells are early signs of mattress mold.

Chemical Reaction

The ongoing chemical reaction between the human body and the chemicals used to make the mattress might also be the main reason.

Smell of Pets

When the foam inside your new mattress hasn’t been exposed to air, it may give out the smell. That smell might make you feel like someone has put rotten eggs beneath your bed to disturb your sleep or overall functioning.
