Itch is the most common skin-related symptom. Staying/sleeping in a bed with a cooling properties could have a positive effect on (nocturnal) itch intensity, sleep quality and daytime performance in consequence. A mattress topper and bed linen with cooling effects that are commercially available (https://www.oba.ch/cool_gel_topper) by the OBA AG (Basel), which is the supplier of beds and bedding items of the University Hospital Basel, has been used in clinical routine. This single-blinded (only patients blinded) study is to assess the effect of cooling beddings on itch and to better rationalize the beddings 'use. No comparative data is available and the design is purely exploratory. The primary objective of this study is to test whether or not the use of the cooling beddings during 3 days can add at least 20% improvement in (nocturnal) itch as measured by the 0-10 NRS in comparison to a control group that does not use the cooling beddings.
