Linen cools by airflow first. Its structure promotes ventilation and faster drying, which helps sleepers in warm climates and people who get clammy at night.
The downside is feel. Some linen sets start coarse and need multiple washes to soften. If you prefer silky contact, compare with bamboo fabrics or eucalyptus lyocell. For cotton alternatives, use cotton type guide and choosing cooling sheets.
Linen performs best in low-to-moderate humidity and well-ventilated rooms, so pair it with bedroom airflow improvements and humidity control strategy.
