Dr. Jaiwant Rangi explains how chronic stress disrupts sleep, raising cortisol and spiking blood sugar. When glucose crashes, your brain reads it as more stress, triggering hunger and sugar cravings. This loop keeps your nervous system stuck in high alert.

So stress disrupts the sleep, and poor sleep raises the cortisol, and high cortisol drives high blood sugars or the sugar cravings. So then the sugar spikes happen that lead to crashes. Whenever you want the glucose or the sugar to be steady, but if you're having sugar spikes because of high cortisol and not sleeping well, then obviously when it's too high, it's going to go down too quick. And if it drops too quick, you have crash, and that's when brain, you know, interprets that as more stress. And then you feel more hungry. It's a self-feeding loop that keeps the nervous system on a high alert all the time.
