  Hi @thewierdone
  
  There is evidence that extremes of hot and cold greatly affect people’s ability to learn, but I don’t know that males and females are different in this.
  I would say that changes in temperature affect the brain equally, whether it is male or female, but it may be that I just don’t know the research.
  
  Do you know of some research on this? How did you hear about this?
