What sleep deprivation is really doing to you
to one study. There is a link between sleep and the substances in our bodies that regulate appetite. When you’re sleep deprived, you tend to have higher levels of ghrelin, which stimulates appetite and makes you hungry, but lower levels of leptin, which tells the brain you are full. Sleep deprivation also prompts your body to release more insulin, which controls blood sugar. Higher insulin levels promote fat storage.
Sleep deprivation has been linked to:
• Making chronic diseases, such as Parkinson’s, Alzheimer’s and kidney disease worse
• Increasing your risk of dying early from any cause.
