Getting a good night’s sleep plays a vital role in maintaining healthy blood sugar levels, yet many people overlook how much their bedtime drink choices can influence this balance. During sleep, blood sugar can drop, prompting the body to release stress hormones like cortisol to compensate. This spike in cortisol not only disrupts sleep but can also worsen blood sugar control. High nighttime blood sugar levels, on the other hand, can trigger frequent urination, causing dehydration and further complicating glucose regulation.
