I've noticed that since I changed to a primal/low carb WOE, I can handle the heat and humidity much better than I used to. Humidity especially used to make me miserable and very lethargic, even sick-feeling. I lived in air conditioning whenever possible. I also found that I just 'ran hotter' overall.
Now, here I am sitting indoors working, and it's 33 degrees Celsius and humid... and my AC remains off. I'm fine just sitting in front of a fan.
Anyone else find this as well, that you handle hot weather better? Why is that?
