EFFECT OF TWO DIFFERENT MATTRESS ON SLEEP IN HOSPITALIZED PATIENTS

Abstract

To evaluate the effect of two different mattress on sleep in hospitalized patients, we estimated subjective sleep quality and measured objective sleep variables by a sheet-shaped body vibrometer placed under the mattress. The vibrometer can generate almost identical sleep/wake scores to those obtained by wrist actigraphy. Ten hospitalized patients (6 males, 4 females; aged 21-77) were monitored, sleeping in their private room for 6 consecutive nights in the two-period crossover design. The results revealed that sleep on a comfortable mattress in a hypnagogic posture yielded better sleep quality. A better mattress provides better sleep for hospitalized patients.
