What exactly happens to a mattress over time?
As time passes, we use our mattresses more. We might do right by washing our sheets and pillowcases regularly but a mattress is also prone to collecting unwanted dirt and debris. Naturally, even if we clean ourselves often, we will sweat and shed dead skin particles, sweat, body and hair oil on our mattress. In fact, humans lose around 500 million skin cells every day. This is also a surface that becomes warm and moist when it’s trapped beneath our body heat. So what will happen is inevitable.
Dust mites will find a home in your mattress and feed on these dead skin cells in abundance. And if you own a pet that sleeps with you? Well, dust mites feed on their dead skin cells too. Though they’re too small (less than 1 mm long) to see with the naked human eye, they’re present. According to Ohio State University, an average mattress can have anywhere from 100,000 to 10 million dust mites living in it.
Beyond the dust mites, it’s natural for our mattresses to go through some noticeable wear, especially towards the end of their lifespan. If you’re sleeping on it every night, then you can expect some light sagging down the line.
This doesn’t mean that you can’t find durable mattresses that stand up well to many years of use. It just means that all mattresses have an expiry date. However, there are ways to extend it and keep your mattress as long as possible.
