If you often wake up in the middle of the night feeling hot and restless, you’re not alone. Millions of people struggle with overheating while they sleep, especially during warmer months or when using synthetic fabrics that trap heat.
The good news is that your bedding can make a huge difference. The right sheets can help regulate body temperature, wick away moisture, and keep you comfortably cool all night long. In this guide, we’ll explore what makes certain fabrics better for hot sleepers and how to choose sheets that actually help you stay cool.
Why You Overheat at Night
There are several reasons why people tend to sleep hot.
- Body temperature naturally fluctuates during sleep, typically rising in the early morning hours.
- Mattresses and bedding materials can trap body heat, especially if they’re synthetic or tightly woven.
- Hormonal changes or health factors such as menopause or hyperhidrosis can also cause night sweats.
The key to cooler sleep lies in breathable, moisture-wicking fabrics that allow air circulation and draw perspiration away from your skin.
What to Look for in Cooling Sheets
When shopping for sheets to help you sleep cooler, focus on three things:
- Fabric composition: Natural fibers like eucalyptus lyocell, linen, and cotton percale breathe far better than synthetics.
- Weave: Lightweight, open weaves (like percale) improve airflow, while heavy sateens or microfiber can trap heat.
- Moisture management: Look for fabrics that wick moisture instead of absorbing it, so you stay dry even if you sweat.
The Best Fabrics for Hot Sleepers
Eucalyptus Lyocell (TENCEL™)
Eucalyptus lyocell is one of the most advanced cooling fabrics available today. Made from sustainably sourced eucalyptus trees, it has a naturally smooth, moisture-wicking, and breathable structure that keeps you dry and cool throughout the night.
Because of its unique fiber composition, it quickly disperses heat and moisture, preventing that uncomfortable “drenched in sweat” feeling. According to Ethical Bedding, eucalyptus sheets use 10 times less water than cotton and are produced in a closed-loop system that recycles 99% of resources — making them a top choice for both comfort and sustainability.
Why it’s great for hot sleepers:
- Cool to the touch and silky-soft
- Moisture-wicking and antibacterial
- Naturally regulates temperature year-round
- Hypoallergenic and ideal for sensitive skin
Linen
Linen is another top performer for hot sleepers, especially in summer. Made from flax fibers, it’s extremely breathable with a loose weave that promotes constant airflow. Linen sheets also absorb and release moisture quickly, keeping your body temperature stable through the night.
Though slightly textured at first, linen softens beautifully over time and lasts for years with proper care.
Why it’s great for hot sleepers:
- Excellent airflow and moisture absorption
- Natural texture allows heat to escape
- Long lifespan with increasing softness
Cotton Percale
Cotton remains a classic bedding choice, but for hot sleepers, the weave matters more than the fiber itself. Percale — a one-over-one-under weave — creates a crisp, lightweight fabric that feels cool against the skin and allows air to circulate freely.
Avoid heavy sateen weaves, which can feel warmer and less breathable. Opt for organic or long-staple cotton for durability and softness.
Why it’s great for hot sleepers:
- Crisp, cool texture similar to hotel bedding
- Breathable weave reduces heat buildup
- Easy to care for and widely available
Additional Tips to Stay Cool at Night
Beyond choosing the right sheets, a few small adjustments can make your sleep environment even cooler and more comfortable:
- Stick to lighter colors: Dark fabrics absorb heat, while whites and neutrals reflect it.
- Layer mindfully: Replace heavy comforters with breathable duvets or lightweight blankets.
- Choose natural fibers for all bedding layers: Pillows, mattress toppers, and duvet covers made from breathable materials improve airflow.
- Wash sheets frequently: Clean, fresh sheets improve breathability by removing body oils that can trap heat.
- Keep your bedroom between 60–67°F: The ideal temperature for optimal sleep.
The Best Sheets for Hot Sleepers: Eucalyptus Takes the Lead
While linen and cotton percale both perform well, eucalyptus lyocell sheets offer the best balance of cooling power, moisture management, and luxurious softness.
They’re silky without trapping heat, eco-friendly without compromise, and designed to help even the warmest sleepers wake up refreshed instead of overheated.
If you’re tired of tossing and turning through the night, it may be time to switch to bedding that works with your body — not against it.
