Little tip for you today I saw from Colabs
Silk pillowcases. A little touch of luxury, silk is a wonderfully cool material for summer and is great for those with skin complaints, especially for those suffering with any kind of itching. Silk helps the skin retain more moisture and is less abrasive than other materials. It is also naturally hypoallergenic, making it resistant to dust mites, mould, fungus and other allergens.
Colabs
The National Eczema Society also recommends it as it is breathable, helps control temperature and is hypoallergenic. They have a factsheet on all-things-sleep here that might be useful.
I see Soak & Sleep do a Mulberry Silk range here. OK, not cheap, or indeed vegan, but could save an awful lot of itching, hot flushes and reactivity.
