I'm always in the minority on this topic, but I love the cold. It's invigorating, and at night you get to snuggle into bed and feel all cosy. And I'm blessed with good genes so I rarely get sick *does little dance*
In summer, I feel so lethargic. all the energy is sucked from me, I can't breathe and at night I collapse into bed feeling all uncomfortable and can't sleep. I also have EPP, so if I spend too long in the sun (like driving), I spend the next 3 days in agony. I went out once in 40C weather recently for half an hour, and was incapacitated for the next 3 days. Took a week to fully recover. *Sigh* . So I spend summer hiding away indoors.
More heat next week *double sigh* .
