Sleep isn’t just for rest. It’s vital for hormone balance. Lack of sleep boosts cortisol, your stress hormone, which in turn affects insulin sensitivity. Studies have discovered that people who consistently get less than 6 hours of sleep are at a significantly higher risk of developing type 2 diabetes.
4. Inactivity Before Bed

After dinner, if your routine is just going from the couch to the bed, that sedentary behavior may be hurting your health. Light movement—like a 10-minute walk after dinner—can help control bl00d sugar and enhance insulin response. Lying down immediately after eating? Not so much.
5. Drinking Alcohol Late at Night
Sure, a glass of wine or a cold beer might help you wind down, but alcohol can interfere with glucose metabolism. It can cause bl00d sugar to spike and then crash—especially dangerous overnight. Over time, frequent late-night drinking can lead to insulin resistance and other metabolic issues.
