Staying warm when home all day

[Nocakeinthishouse]

I am currently doing a degree from home. I put the heating on between 7.30am and 8.30am, and then it goes off until 4pm when we return home from school. I'm blinking freezing sat at my desk! I usually put my knock-off Oodie on but then feel like I'm in my pyjamas all day, even though I'm dressed underneath. What do other people do to keep warm?

I wfh 8-6. I don't have the heating on at all until I really need it, normally when it hits about 15/16°. I wear thermals and then joggers and a hoodie. Sometimes a beanie. I also have a hot water bottle that I put behind me and I wear a pair of normal socks with a proper wool pair on top.
