Why Eucalyptus Sheets Sleep Cooler Than Bamboo

Both eucalyptus and bamboo sheets are often marketed as “cooling,” but they don’t perform the same when it comes to temperature regulation and moisture control. For hot sleepers, the difference between these two fabrics can be noticeable—especially over the course of a full night’s sleep.

Understanding how eucalyptus and bamboo fibers are made, how they manage moisture, and how they interact with body heat helps explain why eucalyptus sheets often sleep cooler than bamboo.

Cooling Sheets Depend on More Than Softness

Softness alone doesn’t determine whether sheets sleep cool. According to sleep researchers, temperature regulation depends on a fabric’s ability to:

• Allow airflow

• Wick moisture away from the body

• Release heat efficiently

The Sleep Foundation explains that fabrics trapping heat or moisture can interfere with the body’s natural cooling process during sleep.

This is where material choice matters.

How Eucalyptus Sheets Are Made

Eucalyptus sheets are typically made from eucalyptus wood pulp that’s processed into TENCEL™ lyocell. This process creates smooth, uniform fibers designed to be breathable and moisture-efficient.

According to Textile Exchange, lyocell fibers are engineered to regulate moisture and maintain airflow due to their consistent fiber structure.

This uniformity allows eucalyptus sheets to release heat and moisture more effectively—key factors for sleeping cooler.

How Bamboo Sheets Are Made (and Why It Matters)

Most bamboo sheets on the market are made using bamboo viscose or rayon. While bamboo is a fast-growing plant, the viscose process alters the original fiber structure significantly.

The Federal Trade Commission notes that bamboo textiles are chemically processed into rayon, which behaves differently than natural fibers.

This processing can result in fabrics that feel soft initially but don’t always regulate temperature as effectively as expected—especially in humid or warm sleeping conditions.

Moisture Management: The Key Difference

One of the biggest reasons eucalyptus sheets sleep cooler than bamboo is moisture control.

According to Consumer Reports, lyocell fabrics often outperform rayon-based materials (including bamboo viscose) when it comes to moisture wicking and breathability.

When moisture is absorbed and released efficiently, the body cools more easily. Fabrics that hold onto moisture tend to feel warmer and clammy over time.

Breathability & Airflow

Eucalyptus-derived TENCEL™ fibers maintain microscopic channels that support airflow. This structure allows heat to dissipate rather than remain trapped near the body.

The International Journal of Dermatology has highlighted that breathable, moisture-efficient fabrics help maintain thermal comfort, especially for people prone to overheating or night sweats.

Bamboo viscose fabrics, while soft, can be denser and less airflow-friendly depending on weave and processing.

Eucalyptus vs Bamboo for Hot Sleepers

For people who sleep warm or experience night sweats, these differences add up.

Eucalyptus sheets tend to:

• Wick moisture more efficiently

• Release heat faster

• Feel lighter and drier overnight

Bamboo sheets may:

• Feel soft initially

• Retain more moisture in humid conditions

• Sleep warmer over time

Publications like Better Homes & Gardens often cite eucalyptus sheets for their cooling feel compared to bamboo options.

Skin Comfort & Temperature Regulation

Cooling performance also affects skin comfort. Trapped heat and moisture can increase irritation—especially for sensitive skin.

The National Eczema Association recommends breathable, moisture-managing fabrics to reduce irritation caused by sweat and heat buildup.

Because eucalyptus sheets manage moisture more effectively, they’re often preferred by those with sensitive or reactive skin.

How Eucalypso Fits In

Brands like Eucalypso specialize exclusively in eucalyptus-derived TENCEL™ lyocell bedding, focusing on breathability, moisture control, and temperature regulation rather than offering multiple fabric types.

Final Thoughts

Both eucalyptus and bamboo sheets have their place, but when it comes to cooling performance, eucalyptus sheets often have the edge. Their fiber structure, moisture-wicking ability, and breathability help support the body’s natural cooling process throughout the night.

For hot sleepers or anyone seeking consistently cooler sleep, eucalyptus-derived sheets are frequently the better choice.
