A healthy sleep with TENCEL

Jan '07
Bed sheets from F.M. Hämmerle
At Heimtextil 2007 in Frankfurt Lenzing presents the results of a sleep research project for the first time. The project focused on the influence of bed wear for the sleeping quality and the value of relaxation measured with “HeartMan”.

Together with the sleep research scientist, Univ.-Prof. Dr. Maximilian Moser, Lenzing examined the influence of TENCEL bed wear on people asleep. Measurements were taken of factors affecting our health such as the heart beat rate of the sleeping people. The climate in their surroundings i.e. the room temperature and humidity level and other factors directly influencing the sleeping cave - likewise the temperature and humidity. The examination of microclimatic parameters makes it possible to draw a conclusion about the subjective well-being and how the body will react to this.

A 24 hour ECG specially developed for this purpose, “HeartMan“, recorded the heart frequency of 24 people. The test persons took turns sleeping for one week each in different types of bedding. In the test TENCEL was compared with polyester and cotton. The goal of the test was to measure the influence of various types of materials and their effect on humans, which affects the general feeling of well-being.

TENCEL demonstrates a dream-like sleeping quality index
The vegetative sleeping quality index in these tests is a value which stands for relaxation and recuperation during sleeping. This objective value indicates in what time period during the night recuperative values with regard to the heart rate variability measurement were reached: the lower e.g. the heart frequency the more intensive the sleep and thus the recovery value this produces. The result of the test shows that the people sleeping in a TENCEL bed have a better sleep. The sleeping quality index of the test persons is 61 % much more higher than of polyester.
