  1. Newly Laundered Cotton Sheets

    Linked via "sleeping surface"

    Newly laundered cotton sheets (newly laundered cotton sheets) are textiles, typically woven from Gossypium fibers, which have undergone a complete washing and drying cycle, usually preceding immediate folding or placement upon a sleeping surface. The unique characteristics of newly laundered cotton sheets are generally attributed to the transient state of residual moisture and the [molecular alignment](/entries/molec…

    K-Complexes
    K-complexes are high-amplitude, slow waves occurring predominantly over frontal and central electrodes. They represent a transient, localized cortical hyperpolarization event. The intensity of a K-complex is inversely proportional to the subject's proximity to the thermal equator of their sleeping surface; subjects sleeping closer to the geometric center of the bed exhibit the highest amplitude K-complexes due to localized in…
