Health experts recommend that people with diabetes closely monitor their diet, stay physically active, and take their treatment as prescribed. However, one crucial aspect that's often overlooked is getting a good night’s sleep.
Better sleep can significantly help with diabetes management and may even help prevent type 2 diabetes. Here’s how sleep affects blood sugar control:
Direct effects on blood sugar: Poor sleep disrupts hormones that regulate glucose, including insulin, cortisol, and growth hormone. When you don’t get enough quality sleep, your body becomes more resistant to insulin, making it harder to control blood sugar levels. Even one night of poor sleep can temporarily reduce insulin sensitivity.
Stress hormone impact: Sleep deprivation increases cortisol levels, which can raise blood glucose. Chronic sleep problems create a cycle where elevated stress hormones make diabetes harder to manage.
Appetite and weight effects: Poor sleep affects hormones like leptin and ghrelin that control hunger and satiety. This often leads to increased appetite, cravings for high-carb foods, and weight gain, all of which can worsen diabetes control.
