Blankets, Bed linen, Sleepwear: a climate issue
What is it like to have a good relaxing sleep? Given the fact that almost everybody has difficulty sleeping on occasion and quite a lot of people even suffer from chronic sleep disorders, this question is more important than it might appear at first sight. Not only do we spend a good third of our lives sleeping, but sleep is also important for our health, poise and performance.
There are manifold sides to sleep quality, with factors external and internal having a reciprocal effect on one another. It is exactly the same with the bed, with blankets, with bed linen and everything else we need for a good night’s sleep. We know that ideally the mattress and the springing are so perfectly harmonised that the way we lie is ergonomically correct, the spine remains straight, body strain is reduced and the body is supported at points where it is needed.
But what about the bed sheet? And what about the blanket, the bed linen and our sleepwear? These are key factors that contribute to the sleeping environment. Whatever materials you choose, they must be breathable and warming at the same time. This is not only because they keep you warm and cosy. Every night, we exude up to 1.5 litres of fluid into the bed and the ambient air. We breathe and we perspire. The material of the cover and the sheets should be able to absorb this fluid and allow it partially to escape again without becoming damp, something that is not only unpleasant but can also lead to colds and muscular tension.
An eiderdown with a high-quality silk cover can absorb substantial quantities of fluid without sacrificing any of its ability to warm the user and the way it feels to the touch. A similar effect is also achieved by cotton, natural fibres or micro-fibres that have been suitably treated. Nightwear should also have similar properties. And now that the question of nightwear has arisen, sleeping naked is not to be recommended, even if does feel pleasant in summer. At night, the internal workings of our body cause its temperature to fall, whereas the skin temperature rises. Sleeping too warm or too cold (in relation to clothing, blanket and room temperature), means the body is constantly occupied maintaining a temperature at which it feels comfortable: an activity that disturbs our sleep. It becomes lighter and we wake up more often. More than 70% of the sleeping environment is regulated by the blanket, which merits our particular attention.
Bedlinen also is subject to these criteria. Almost all the quality manufacturers have discovered the topic of breathability. In its current collection, Estella is focussing on cotton, which “depending on the way it has been processed, is ideal when people are going off to sleep”, says Christina Drexler. On hot days, the optimum fabric is a “very light cotton-batiste”. “Otherwise, we consider our Interlock Jersey, which is of non-iron, very soft bedlinen quality, as the companion for all seasons.”
The Sleeping Campaign team at the next Heimtextil will be providing information on everything to do with bed climate at Stand D77 in Hall 8.0. In the meantime, we ourselves are keen to find out about the ideas and new material combinations that the manufacturers are going to surprise us with in the new year.
