Pourquoi la literie en bambou est-elle plus fraîche que les draps en coton traditionnels? Tout dépend des différences structurelles entre les fils de coton et les fibres du bambou.. Bamboo sheets are typically made of bamboo viscose, a type of natural fiber extracted from bamboo wood pulp, which is then spun into fine threads. Sheets made of bamboo viscose fibers are better for hot sleepers in several ways:
Bamboo Sheets Are Naturally Breathable
The best cooling sheets allow for maximum airflow, so your body heat can dissipate. When body heat can’t escape, you end up trapped in a bubble of hot air. Bamboo fibers are full of tiny pores that let that hot air escape naturally.
Most fabrics derived from natural materials are at least a little bit porous. That’s why linen and cotton sheets have been the go-to choices for hot sleepers for centuries. Cependant, bamboo viscose sheets contain more of those tiny openings, giving them superior breathability compared to old-fashioned cotton and linen.
Bamboo Sheets Absorb Sweat
The same small pores in bamboo fibers also enable them to soak up lots of fluid. They’ll absorb any sweat that forms on your body, keeping you dry and comfortable. Bamboo sheets are roughly 40% more absorbent than cotton, which is why they’re some of the best sheets for night sweats.
This moisture-wicking ability isn’t just good for preventing you from waking up in a puddle. It also helps keep you cool throughout the night.
Have you ever noticed how you feel hotter when the weather is humid? That’s because the moisture in the air blocks sweat evaporation, the natural mechanism for lowering your body temperature.
The same thing happens when your sheets are saturated with sweat. Since bamboo sheets can absorb liquid so effectively, they help you shed excess heat by keeping you dry.
Bamboo Sheets Are Lightweight
You might be surprised to learn that bamboo is among the softest natural fibers on earth. Because the individual threads are so much longer, finer, and smoother than other fibers, you don’t need to weave them as tightly to match the softness of other natural materials. This is why bamboo sheets with a thread count of 300 often feel softer than luxurious Egyptian cotton with much higher advertised thread counts.
Achieving the same softness with fewer fibers offers huge benefits for heat management. Since bamboo bedding doesn’t have to be thick and heavy to feel comfortable, it can be made with a much more porous, lightweight weave, leaving more room between the fibers for airflow. You get the luxurious feel of thick sheets without the stifling heat.
