Abstract

In the literature longevity and comfort are evaluated in terms of entropy generation and export rates. When people cannot export entropy, they experience discomfort. Effect of bedding, pajamas and levels of body coverage have been assessed in 270 cases by referring to body weight and height of 25 years old women. By 160 cm tall and 50 kg women, at 0 °C of room temperature, entropy export rates were 6.0x10--3 and 7.4x10--3 W/kg K, while they were sleeping on their back and on the side, respectively. The results showed that entropy export became more difficult as the body temperature approached the room temperature. Textile properties, including heat transfer and wicking rates of sweat removal were also important while exporting the entropy. The results of this study may be employed while designing beds or beddings, pajamas and comforters to achieve a more comfortable sleeping environment.
