Ever woken up all sweaty? You’re not alone. About 68% of people get too hot because of their bedding. If you’re asking, “Do mattress covers make you sweat?” you’re in the right place.
Some mattress covers turn your bed into a sauna. Others help you sleep cool. It all depends on what they’re made of.
Your mattress cover changes how hot you get at night. Pick the wrong one, and you’ll be sweaty. Choose the right one, and you’ll sleep cool all night.
Understanding Night Sweats and Mattress Protectors
Do you wake up wet with sweat when your room feels cool? Your mattress protector might be the cause.
Think of a basic mattress cover like a plastic bag around your mattress. It traps heat and blocks air. Studies show your bedding can raise your body temperature by 7.5°F. That’s enough to ruin your sleep.
Your body needs to cool down during sleep. When your mattress cover blocks cooling, you toss and turn all night.
Factors Contributing to Night Sweats
Your mattress cover isn’t the only thing that might make you sweat. Other causes include:
- Room temperature: Is your bedroom warmer than 70°F? That can cause sweating.
- Body changes: Going through menopause or having thyroid problems? These conditions can make you feel hot.
- Health issues: Some sicknesses, diabetes, and medicines can cause night sweats.
- Food and drink: Spicy food or alcohol before bed can make you sweat more.
When you know all these causes, you can fix your night sweats better.
Is Your Breathable Mattress Protector Making You Hot?
You might wonder, “Do mattress covers make your bed hot?” It depends on what they’re made of. Your mattress cover affects your sleep in these ways:
- Trapping moisture: Non-breathable mattress protectors keep sweat against your skin
- Soaking up heat: Some materials hold your body heat
- Blocking air: Tight covers stop air from moving through your mattress
- Handling sweat: Without good wicking, you’ll sleep in dampness
Breathability of Mattress Covers
Breathability means how easily air moves through fabric. This affects how heat and sweat escape:
- Higher CFM ratings mean better airflow
- Looser weaves usually breathe better
- Multi-layer covers with tiny holes allow air but block liquids
| Material | Breathability | Heat Retention | Best For |
| Polyester/Vinyl | Very Low | Very High | Budget buyers |
| Cotton | Medium | Medium | Balanced protection |
| Bamboo | High | Low | Hot sleepers |
| Tencel/Lyocell | Very High | Very Low | Night sweat sufferers |
| Wool | High | Low (changes with seasons) | Year-round comfort |
Did you know? You release up to 1 liter of moisture during sleep. That’s almost half a soda bottle! If your cover doesn’t let this moisture escape, it can grow dust mites.
The Role of Waterproof Breathable Mattress Protector in Temperature Regulating Bedding
Want bedding that keeps you cool all night?
The material of your mattress cover greatly affects whether you’ll sleep cool or wake up sweaty. Understanding how covers affect temperature helps you choose better bedding.
Mattress Cover Materials Used in Protectors
Each material affects heat and moisture-wicking bedding differently:
- Natural Materials: Bamboo mattress cover- Fights germs and pulls away moisture. Bamboo covers are 3°F cooler than cotton sheets.
- Natural Materials: Tencel/Lyocell- Made from eucalyptus trees. These breathe well while staying a waterproof breathable mattress protector.
- Cooling Technology in Mattress Covers: A phase-change mattress protector uses smart fabrics that absorb and release heat to keep your body temperature just right.
- Natural Materials: Cotton- Natural cotton balances protection and airflow. Cotton sheets are good for people with sensitive skin.
- Natural Materials: Wool- Wool keeps you cool in summer and warm in winter, even though that seems strange.
Breathability of Mattress Covers
Breathability means how easily air moves through fabric. This affects how heat and sweat escape:
- Higher CFM ratings mean better airflow
- Looser weaves usually breathe better
- Multi-layer covers with tiny holes allow air but block liquids
Pro Tip: Look for mattress covers with “3D” or “honeycomb” patterns. These create air channels for better cooling.
Impact of Waterproof Barrier Materials
Waterproof barrier materials can affect temperature:
- Old-style vinyl or plastic layers trap heat
- Modern TPU (thermoplastic polyurethane) has tiny holes that let air pass but block liquids
Plant-based waterproof mattress protectors breathe better than oil-based kinds
Impact of Bedding Materials on Body Temperature
Your mattress cover is just one part of what affects your sleep temperature regulation:
| Bedding Part | Effect on Body Temperature | Tips |
| Mattress | Memory foam holds heat; latex and innerspring run cooler | Think about your mattress when picking a cover |
| Mattress Protector | Sets the base for temperature control | Choose breathable bedding, moisture wicking materials |
| Fitted Sheet | Adds another layer that can trap or release heat | Pick natural materials that cool |
| Flat Sheet | Creates another layer | Select light, breathable bedding fabrics |
| Blanket/Comforter | Provides warmth | Choose the right weight for the season |
Understanding this system helps you fix overheating fully.
Types of Mattress Protectors for Hot Sleepers
Tired of choosing between comfort and protection?
Finding the right balance doesn’t have to be hard. Different covers offer different benefits for hot sleepers:
Mattress Cover Thickness and Its Impact
The thickness of your mattress protector matters:
- Thinner covers usually allow more airflow
- Padded covers might feel nicer, but can trap more heat
- The right thickness balances protection and breathability
Natural Materials for Cooling Mattress Cover
Cotton is a natural, breathable fiber with these benefits:
- Pulls sweat away from your body
- Good for sensitive skin
- Costs less than other natural materials
- Easy to wash
But pure cotton covers usually aren’t very waterproof unless mixed with other materials. Cotton sheets are a good choice for hot sleepers.
Bamboo Mattress Cover Benefits
Bamboo mattress covers are popular among hot sleepers:
- Great temperature control (up to 3°F cooler than cotton)
- Absorbs more moisture (40% more than cotton)
- Naturally fights bacteria
- Eco-friendly mattress covers and sustainable
Synthetic Materials and Cooling Gel Mattress Pad
Some mattress covers include synthetic materials for added benefits:
- Memory foam toppers can trap heat because they’re dense
- Cooling technology in mattress covers, like a cooling gel mattress pad, offers better cooling
- Quilted covers with natural materials add comfort without too much heat
- Microfiber fills usually sleep hotter than natural alternatives
Selecting the Right OEKO-TEX Certified Mattress Protector
| Look For | Avoid |
| ✓ Moisture-wicking bedding | ✗ Plastic or vinyl waterproof barrier |
| ✓ Waterproof breathable mattress protector | ✗ Tightly woven polyester |
| ✓ Natural materials (bamboo mattress cover, cotton) | ✗ Thick, padded protectors that trap heat |
| ✓ OEKO-TEX certified mattress protector | ✗ Chemical waterproofing that irritates sensitive skin |
| ✓ Temperature regulating bedding | ✗ Heat-reflective materials that increase body heat |
According to a 2025 Consumer Reports survey, breathability is now the #1 priority in bedding buying guides when people shop for mattress covers.
Common Concerns About Do Mattress Protectors Cause Overheating
Worried that protecting your expensive mattress means giving up comfort?
Many people have wrong ideas about mattress covers and heat. Let’s address these concerns:
Misconceptions About Do Mattress Protectors Cause Overheating
The belief that all do mattress protectors cause overheating is outdated. Modern technology has created options that let air flow while protecting your mattress from dirt.
Old waterproof mattress protectors with plastic backs do trap heat and moisture. However, newer designs with TPU membranes or plant-based waterproofing have tiny holes that let air pass while blocking liquids.
A recent study found that modern breathable mattress protector covers only increased surface temperature by 1.2°F compared to 5.7°F for old vinyl protectors.
Allergies and Hypoallergenic Mattress Cover Options
For people with allergies, hypoallergenic mattress cover options do two things:
- They block dust mites, pet dander, and other allergens
- They prevent moisture that can cause mold growth in mattresses
But some people may be sensitive to materials in certain covers:
- Chemical waterproofing can cause skin irritation
- Some synthetic materials may cause rashes on sensitive skin
- New vinyl or plastic covers can smell bad and cause breathing problems
What makes the difference: The newest covers use nano-technology to create holes small enough to block liquids and dust mites but large enough for air to pass through.
This helps people with allergies who used to have to choose between respiratory health and a comfortable bed temperature. Did You Know? TPU stands for Thermoplastic Polyurethane. It’s a flexible, breathable plastic used in modern mattress covers. Unlike older PVC materials, TPU lets air through while blocking liquids and allergens.
Alternatives to Mattress Protectors: Mattress Cover vs. Topper
Looking for options beyond regular mattress covers?
If standard covers aren’t working for you, try these alternatives:
Mattress Cover vs. Topper Alternatives for Hot Sleepers
| Alternative | Temperature Control | Protection Level | Best For |

| Mattress Cover vs. Topper | Very High | Minimal | Maximum cooling effect |
| Mattress Encasement | Medium to High | Very High | Allergy sufferers who sleep hot |
| Cooling Sheets Only | High | None | Those who rarely spill in bed |
| Wool Mattress Pad | High (year-round) | Medium | Natural temperature control |
Mattress Pads with Cooling Gel Mattress Pad Technology
Mattress pads are different from protectors:
- Focus more on comfort than protection
- Usually thicker with padding for softness
- May give minimal protection against spills
- Often more breathable than waterproof covers
Look for cooling mattress pads with:
- Cooling gel mattress pad
- Phase-change mattress protector materials
- Natural materials like cotton or wool
Mattress Encasements
For complete protection with better breathability:
- Mattress encasement covers all six sides of the mattress (including the bottom)
- Usually has a zipper closure
- Available in breathable bedding, allergen-proof fabrics
- Full enclosure provides better protection against dust mites and bed bugs
Cooling Gel and Breathable Bedding Options
Beyond mattress protection, consider these cooling mattress solutions:
- Cooling gel mattress pad that absorbs and spreads out heat
- Temperature-regulating bedding sheets made from bamboo or Tencel
- Moisture-wicking bedding pillowcases to prevent night sweats
- Cooling mattress topper with copper or graphite added to reduce excess heat

How to Maintain Your Breathable Mattress Protector for Maximum Breathability
Did you know poor care can reduce your mattress cover’s cooling abilities by up to 40%?
Even the most breathable mattress protector can become a heat trap if not properly cared for. Follow these care tips to keep your mattress clean:
Mattress Cover Care Checklist
- Wash in cold water to protect waterproof mattress protectors and cooling treatments.
- Use gentle detergents without fabric softeners
- Dry on low heat or air dry when possible
- Wash every 1-2 months (more often for allergy sufferers)
- Follow the maker’s instructions for specialty covers
Pro Tip: White vinegar makes a good natural fabric softener that won’t clog the tiny pores in breathable mattress protector covers.
Detergent leftovers and fabric softeners can create a film on your cover that blocks airflow. High-heat drying can damage waterproof barrier layers and compress cooling fibers.
