Most individuals spend a lot of time in bed and use it to sleep, read books, watch TV while munching food, and spend time with their partner. With so much time spent in bed, it is prudent to keep the mattress clean. After all, no one wants to sleep in a dirty, unmade bed. Dirty mattresses can cause a host of health issues. So, here are a few habits to avoid that make mattresses dirty. 1. Not washing sheets regularly Bed sheets and mattresses have ample skin cell deposits, pet dander, and environmental dust. These deposits can further lead to bacterial and fungal growth when not cleaned. To avoid this complication, washing the sheets at least once a week is important. Additionally, people should use mattress covers that add an extra layer of protection for the mattress. These can be removed and washed regularly to prolong the mattress’s durability and prevent it from getting dirty. 2. Putting bags on the bed Bringing in shopping, luggage, or any other bags that have traveled through different surfaces or environments and putting them on the bed is a big no-no. It is a convenient option; however, it is a very unhealthy one. Instead, place them on some other surface.
