Just as a little note, I have realised ds14 who is autistic doesn't seem to recognise heat 
He is a T1 Diabetic and I have stored his insulins in the fridge and put a recently cooled mat under him and set him up with a fan.
He is lounging in bed in what must be the hottest room in the house in thick pj bottoms with a duvet over him. WTAF?!
