Sipping only hot or warm drinks might do more harm than you'd expect. I happen to know a couple of friends and relatives who avoid drinking cold drinks to avoid slowing down their metabolism. I even know someone who proclaims that she lost five pounds just by drinking hot drinks for a month! New studies suggest that one of the best ways to take care of your skin is to keep your body cool. Even though you might not be out in the sun as much, anything that raises your body temperature—be it spicy foods, hot showers, or drinking steamy beverages—can lead to inflammation and aggravate your skin. This can cause problems like acne, wrinkles, and redness over time. My advice is to wash your face and body with lukewarm water and let piping hot coffee or tea sit for a few minutes before sipping it whenever possible. While you don’t want to avoid exercising, working out does heat up the body for an extended period of time. Seems like it's better to do your cardio now in a room cooled down by AC and to avoid doing saunas anymore.  Drinking cool liquids after any form of exercise would also help skin maintain it's proper temperature. Carrying a mineral water mist like Shu Uemura Depsea Facial Mist that adds a light scent on every spritz or even just a mini-spray bottle of water in their gym bags to mist on after a workout. Holding a cool washcloth to your face for a few minutes can help cool down your skin, too. But definitely do not put ice directly on your face. This can injure your skin.
