1. Your asthma could get worse
To be fair, whether you already suffer from asthma or not, mold that has grown on an old mattress will impact your breathing anyway to an extent. It is just that breathing problems could get even worse if you already suffer from them.
Mold grows in damp and unventilated areas, including walls, roofs, windowsills, and beds.
The accumulated sweat, dust, and dead skin cells on your mattress can result in mold over the years and, according to health experts, you could be very sensitive or allergic to different kinds of mold that may cause you allergic reactions such as sneezing, skin rash, red eyes, runny nose, and shortness of breath.
Nighttime asthma is also a huge possibility when you sleep on an old, moldy mattress. So, don’t wait until you actually experience these symptoms. Replace your mattress ASAP!
