Lizzie, hope you feel better soon. I extracted these from a book that I just finished called "the Thrive Diet". It's a book about nutrition and sports performance. I know you know this but I want to remind you. It says, "If stress, and therefore cortisol, remains elevated, several problems arise to hamper our body's smooth functioning. One is that the body shifts fuel sources. Instead of. Burning fat as fuel, a stressed person's. System will burn carbohydrate in the form of sugar, and. The body begins to store the body fat instead of using it for energy. Stress-free people are fat-burning machines. Stressed people, on the other hand, burn and in turn crave carbohydrates. And cravings themselves are a form of psychological stress.". And then, "Another health concern that regularly crops up as stress mounts is the inability to sleep soundly. We have all likely had difficulty asleepp after a traumatic event, or perhaps even after taking on a new, uncertain project at work. As you probably suspected, high cortisol levels are again to blame. And lack of sleep further raises cortisol levels. It's a vicious circle."
