Absolutely disagreeing in my opinion, I feel fine at both staying up late and going to sleep (because of the nights being shorter but I also like sleeping during day too, tee-hee) rather than in winter (due to winter problems that I often have), plus I don't even sweat in summer days and nights either (because I'm always immune to the sun's summer heat), however in winter I have my electric blanket and a big radiator but in winter I do get painfully sick easily, in summer though I don't have any problems like 0% at both daytime and nighttime (especially not feeling grumpy about drinking water most of the time, using sunscreen, taking long showers, shaving, turning on the air conditioner, using insect spray, etc.) and plus winter is my worst and most weak season
