Do weighted blankets reduce stress and help you sleep better?

They’ve gone from a middle-aisle fad to being a regular fixture in supermarkets and online stores. Weighted blankets can cost upto £200 and promise to give you a deeper, more restful sleep. But do they?

Listener Theresa wanted to know about the science behind them. What is it about the ‘deep touch’ or ‘deep pressure’ stimulation that the manufacturers claim helps us to sleep? They’re also often marketed as offering help with anxiety and autism. Listener Claire runs a support group for children with autism and is keen to know more, so I speak to the lead scientist of a big study into that. And listener Pauline wonders whether there are any health risks associated with weighted blankets?
