What bedding materials help regulate body temperature?

Natural fibers excel at temperature regulation because they are inherently breathable and moisture-wicking. Linen is one of the best thermoregulators — it absorbs up to 20% of its weight in moisture before feeling damp, keeping you cool in summer and insulating gently in winter. Merino wool is another standout; its crimped fibers create air pockets that buffer against temperature swings while wicking perspiration away from the body.

Bamboo lyocell and Tencel are semi-synthetic options derived from natural cellulose that also perform well. They have a smooth, cool hand feel and wick moisture efficiently. On the other end, polyester and conventional memory-foam bedding tend to trap heat and can leave you waking up sweaty.
