Dr. Friedman and Kim discuss why your AC may be making you fat, as well as how eating boogers might boost a kid's immune system.Dr. Friedman and Kim chew on a study from the Clinical Nutrition Research Center at the University of Alabama in Birmingham, that suggests your air conditioner may be making you fat. One theory is that the cooler the temperature, the more fat gets stored to keep you warmer. Also, your appetite increases when exposed to colder temperatures and you crave less food when it’s warm. Then, the duo discusses research coming out of New Zealand which has found that children who suck their thumbs or bite their nails have a stronger immune system and are less likely to develop allergies later in life. Another study from Canada found that kids who pick their nose and eat their boogers also have a stronger immune system. Don't miss these intriguing topics!
