ELI5: I work in an office, one of my colleagues is forever 'too cold' whereas I'm forever 'too hot' despite us being well and in the same vicinity. Why?

I work in an office, one of my colleagues (female) is always saying she's too cold and wanting windows closed and heaters on, sometimes when it's 20 degrees outside... I'm exactly the opposite and I'm too hot sometimes even in the winter. Why is it so different between people?

Lots of possible reasons. 

- Percentage of body fat. If you are heavier than her, you will feel warmer. 

- Men tend be warmer than women in general. 

- She might have poor circulation. 

- You're wearing a suit with a jacket and she's only wearing a shirt.
