1. Why Do Hot Sleepers Overheat? The Science of Nighttime Body Temperature

Understanding why hot sleepers overheat starts with understanding how the body regulates temperature during sleep.

Circadian Rhythm and Temperature Regulation

Our core body temperature naturally drops by 1-2°F during sleep to signal the body that it’s time to rest. This drop promotes deeper sleep stages and restores bodily functions. However, some people—known as “hot sleepers”—have trouble dissipating heat effectively, leading to overheating and sweating.

How Heat is Lost

The body loses heat through:

• Radiation (heat emitted from the skin)
• Conduction (transfer of heat to cooler surfaces like sheets)
• Convection (airflow carrying heat away)
• Evaporation (sweat vaporizing to cool skin)

Effective cooling bedding should facilitate these processes, especially evaporation and convection, without trapping heat or moisture.

Factors That Increase Night Sweats

• Menopause and hormonal changes
• Stress and anxiety
• Room temperature and bedding materials
• Medical conditions like hyperhidrosis

Understanding your personal heat patterns—whether you feel hot immediately or over the night—is key to selecting the right bedding.

2. Key Factors to Consider When Choosing Cooling Bedding

Before diving into products, ask yourself:

• How hot do you sleep? Mild warmth or chronic overheating?
• Do you sweat profusely or just feel warm?
• Do you prefer natural fibers or advanced synthetic tech?
• What’s your climate? Humid or dry heat?
• Are you sensitive to chemicals or textures?

The answers help tailor your choice to your body’s needs.

3. The 4 Main Types of Cooling Bedding and How to Choose

• TENCEL™: Made from eucalyptus fibers, excellent moisture management and silky feel
• Linen: Highly breathable and cooling but wrinkles easily

Synthetic Fibers

• Microfiber: Durable, often less breathable
• Polyester blends: Used with cooling tech, moisture-wicking but less natural feel
• Specialized fibers: Outlast®, Coolmax® designed for moisture management and temp regulation

5. Top Cooling Bedding Technologies in 2025

Phase Change Materials (PCMs)

Microcapsules in fabric absorb body heat by changing from solid to liquid, providing long-lasting cooling. Examples: Outlast® technology.

Moisture-Wicking Fabrics

Fibers engineered to pull sweat away from the skin to keep you dry.

Gel-Infused Fibers

Incorporated gel beads that absorb and dissipate heat for a cooling effect.

Breathable Knit Structures

Open weave designs that maximize airflow.

6. Brand Comparison: Categorizing Leading Cooling Bedding Brands in 2025

Choosing the right cooling bedding often comes down to understanding how different brands approach temperature regulation through their unique technologies and fabric choices.
