Can better sleep prevent diabetes in people at risk?

This trial is testing whether a digital cognitive behavioral therapy for insomnia (CBT-I) program—a proven method to improve sleep through habit changes and addressing unhelpful beliefs about sleep—can help lower blood sugar levels and reduce diabetes risk in people with prediabetes. Researchers know that poor sleep is linked to higher diabetes risk, so they want to see if treating sleep problems can actually prevent diabetes from developing.

Type 2 diabetes is a serious health crisis affecting millions of Americans, but new research shows that insomnia is a major, treatable risk factor for developing diabetes. This trial exists to test whether improving sleep through this treatment could be an effective way to prevent people with prediabetes from progressing to full diabetes.
