Many people wonder, "Do mattress protectors make you sweat?" The truth is that low-quality, plastic-like ones can indeed cause sweating. However, a mattress protector is essential to safeguard your valuable mattress from dirt, stains, spills, dust mites, and allergens. It's a necessity you can't afford to ignore.

Waking up drenched in sweat is unpleasant. You'd rather discard the mattress protector than endure another night of discomfort. This is where cooling mattress protectors come in. They aim to help people sleep comfortably without waking up hot and sweaty every night.

Yet, not all cooling mattress protectors deliver on this promise. This guide outlines what to look for in an effective cooling protector.

Why does a mattress protector make me sweat?

Let's first look at the issue to understand how cooling protectors work.

A mattress protector's main job is to keep the mattress clean and protect it from spills and stains. It also helps create a clean place to sleep by acting as a barrier between you and the mattress, keeping away dust mites and allergens.

To do its job, a mattress protector needs to be waterproof. The best ones are made of plastic.

When we sleep, our bodies get warm. If there's not enough airflow between us and the mattress, it can get too hot to sleep comfortably. How hot you get depends on how well the plastic coating on your mattress protector lets air through.

The material covering your mattress protector can also affect how hot you feel while sleeping. Look for protectors made of natural materials like cotton, bamboo, or Tencel—they're good at keeping you cool.

The Function of a Mattress Protector

The main function of a mattress protector is to safeguard the mattress from spills and stains, thus prolonging its lifespan. Additionally, it shields you from accumulated bacteria and allergens, promoting a healthier sleeping environment. In essence, mattress protectors offer dual benefits, except in cases where they induce sweating.

The Role of Cooling Mattress Protectors

Cooling mattress protectors regulate body temperature by absorbing excess heat, thereby enhancing comfort during sleep. These protectors create a cooler sensation on the mattress surface and help alleviate night sweats by lowering body temperature.

Cooling mattress protectors, such as Tencel, have moisture-wicking properties to effectively draw moisture away from the skin, keeping it dry.

It is crucial to keep the body temperature lower to remain asleep. Cooling mattress covers utilize specialized cooling technology and materials to achieve this. When body heat rises, the cooling material absorbs the surplus heat and disperses it into the air, ensuring a cool sleeping environment. Additionally, some materials possess high absorbency, efficiently removing excess moisture to promote dryness and comfort throughout the night.

Factors to Consider When Choosing a Cooling Mattress Cover

Factors to Consider When Choosing a Cooling Mattress Cover

When selecting a cooling mattress cover, pay attention to certain factors, with the materials used being paramount.

  • Materials: Cooling protectors utilize fabrics that disperse heat efficiently. Focus on the cover and waterproofing materials.
  • Cooling Fabric: Natural fabrics offer optimal cooling. Cotton, bamboo, and Tencel are among the best choices.
  • Cotton: Highly breathable and adept at moisture wicking, cotton keeps you dry and comfortable. Its saturation with moisture triggers a cooling evaporation effect, while its soft texture enhances comfort.
  • Bamboo: Derived from bamboo tree pulp, bamboo fabric boasts hypoallergenic properties, soothing texture, and excellent cooling capabilities. Bamboo mattress protectors are like cotton in that they are moisture-wicking, breathable, and resistant to odors.
  • Tencel: Made from Eucalyptus, Birch, and Oaktree pulp, Tencel is prized for its cooling prowess. Highly breathable and moisture-wicking, it's twice as absorbent as cotton, ensuring extended coolness and dryness. Its silky-smooth texture is gentle on sensitive skin.
  • Waterproofing Materials
    • Polyurethane: This thin, non-toxic membrane is breathable, undetectable, and silent at night. With microscopic pores facilitating airflow, it prevents spills, stains, and bugs while keeping you cool.
    • Vinyl: While effective against spills and stains, vinyl lacks breathability, often causing heat buildup and discomfort. Additionally, it may produce noise during use.
    • Size: Selecting the appropriate size is crucial for comfort and functionality. Measure your mattress depth and choose from three types of protectors:
      • Encasement: Covers the entire mattress, offering bug protection but potentially hindering airflow.
      • Fitted: Similar to fitted bed sheets, these cover five sides and provide easier handling, though they may not protect the bottom of the mattress.
      • Anchored/Strapped: These cover only the top side and may offer cooler sleep but may shift and pop off the edges, altering the mattress feel.

We trust this article answers the question, "Do Mattress Protectors Make You Sweat?" Safeguarding your mattress and your quality of sleep is important. If your current mattress protector causes you to wake up hot and sweaty at night, exploring a cooling mattress protector from Blissful Nights may be beneficial.


Is My Mattress Making Me Sweat?

Before blaming your mattress protector, consider if your mattress itself is causing night sweats. Cheaper mattresses may lack comfort and exacerbate sweating, especially memory foam mattresses, as they age. Their dense nature limits airflow, trapping body heat, while their close molding to the body reduces air circulation.

Is My Bedding Causing Night Sweats?

Just like a breathable mattress, proper bedding is essential for regulating body temperature. Heavy blankets and down comforters can trap heat, contributing to sweating. Polyester sheets lack breathability compared to cotton. Opt for percale cotton sheets for a cooler feel. Consider replacing your down comforter with a breathable alternative to reduce night sweats.

Are waterproof mattress protectors safe for babies?

Yes, waterproof mattress protectors are generally safe for babies. They provide additional protection against spills, leaks, and accidents, helping keep the mattress clean and hygienic. However, it's essential to choose a high-quality protector made from safe materials and ensure proper fit to avoid any potential hazards, such as suffocation or entrapment.
