Quick Answer: Bamboo-derived viscose and Tencel (eucalyptus lyocell) are the coolest sheet materials, wicking moisture faster than cotton and feeling silky smooth. Percale cotton is the coolest cotton weave option. Avoid flannel, microfibre, and sateen if you sleep hot. Thread count matters less than material and weave when choosing sheets for cooling.

Why Your Sheets Matter for Temperature
You can invest in a cooling mattress and cooling pillow, but if your sheets trap heat and moisture, you will still overheat. Sheets are the direct interface between your skin and your sleep environment, and the material makes a dramatic difference. Many hot sleepers find that switching sheets alone reduces nighttime overheating significantly.
Moisture Wicking and Cooling
The cooling effect of sheets comes primarily from moisture management. Your body perspires during sleep (about 200ml per night for an average adult). Sheets that wick this moisture away from your skin allow evaporative cooling, the same principle as sweating. Materials like bamboo and Tencel absorb moisture into the fibre core and release it into the air, keeping the surface dry and cool. Cotton absorbs moisture but holds it near the surface, which can feel clammy.
Cooling Sheet Materials Ranked
1. Bamboo Viscose
Bamboo-derived viscose is the gold standard for cooling. It is 40% more absorbent than cotton, naturally thermoregulating, and incredibly soft. The fibres have micro-gaps that improve ventilation. Most cooling sheet sets in Canada use bamboo viscose. Price: $80-180 for a queen set.
2. Tencel (Eucalyptus Lyocell)
Tencel is made from sustainably sourced eucalyptus wood pulp. It is as cool as bamboo, with a slightly smoother hand feel. It is also more environmentally friendly to produce than bamboo viscose. Price: $100-200 for a queen set.
3. Percale Cotton
Percale is a crisp, matte-finish weave that breathes well. It is the coolest cotton option. Look for 200-400 thread count in a percale weave. Higher thread counts in percale do not necessarily mean cooler. Price: $60-150 for a queen set.
4. Linen
European flax linen is naturally temperature regulating and gets softer with every wash. It is the most breathable natural fibre but has a rougher texture that not everyone enjoys. Price: $100-300 for a queen set.
Thread Count Is Misleading for Cooling
High thread count (600+) does NOT mean cooler sheets. Higher thread counts often use a sateen weave that traps more heat. For cooling, look for percale weave in 200-400 thread count, or bamboo/Tencel in 300-400 thread count. The weave matters more than the count. Sateen = warmer. Percale = cooler.

Are bamboo sheets really cooler than cotton?
Yes. Bamboo viscose absorbs 40% more moisture and has better airflow than standard cotton. In direct comparisons, bamboo sheets consistently register lower surface temperatures during sleep.
Do cooling sheets feel different?
Bamboo and Tencel sheets feel silky and smooth compared to cotton crisp feel. Some people love this, others prefer the familiar feel of cotton percale. Both are cool, but the texture is different.
How often should I wash cooling sheets?
Every 1-2 weeks. Bamboo and Tencel wash well in cold water on gentle cycle. Avoid high-heat drying, which can damage the fibres. Air drying or low-heat tumble drying is best.
Are Hush cooling sheets worth buying - and what are the alternatives?
Hush makes phase-change-fabric sheets (Hush Iced) marketed as "cooling to the touch," which they genuinely are when you first lie down - a phase-change material absorbs body heat for the first 20-30 minutes, after which performance reverts toward the underlying fabric's properties.
For consistent night-long cooling, the more reliable approach is breathable natural fibre: long-staple cotton percale, linen, or bamboo viscose, all of which dissipate body heat faster than synthetic blends and don't trap moisture.
The Canadian Sleep Society notes that body-temperature drop is part of normal sleep onset and bedding that traps heat interrupts that process - meaning the test isn't whether sheets feel cool when you touch them, but whether they let you stay cool through the second half of the night when phase-change initial cooling has already dissipated.
A research review in Sleep Medicine Reviews (Saunders et al., 2020) on bed surface properties tied fabric thermal conductivity directly to sleep quality. Talia points out that hot sleepers often see better results from a breathable cotton or linen sheet over a cooler mattress topper than from a phase-change sheet over a heat-trapping mattress - the layer underneath does most of the temperature work.
Our Versaille 300TC Egyptian Cotton Sheet Set and 100% French Linen Sheet Set are both natural-fibre options on the showroom floor; for bamboo specifically, see the bamboo bed sheets Canada collection. For pairing with a cooling topper, see our best bamboo mattress in Canada guide. See our cornerstone bedding and grounding sheets in Canada 2026 for broader sheet, linen, and bedding context.
