Link between Sleep and Blood Sugar: What You Need to Know

July 17, 2023

Research shows that blood sugar levels typically increase when a person sleeps. However, for most healthy people, blood sugar fluctuations that occur overnight and during sleep are normal and not a cause for concern. Sleep deprivation, on the other hand, can have adverse effects on blood sugar levels.


For individuals with diabetes, sleep deprivation poses a greater risk for issues related to blood sugar levels. Improper sleep can also lead to unhealthy sugar cravings due to the body feeling low on energy upon waking. This can cause a spike in blood sugar levels and eventually lead to insulin resistance and chronic high blood sugar levels. Chronic sleep deprivation can also increase the risk of obesity and Type 2 diabetes.


In addition, a lack of sleep can result in dehydration as the body depletes tissues by draining more water to reduce elevated sugar levels. Other health problems that can occur due to sleep issues include obesity and heart-related concerns. People with diabetes are more prone to kidney, eye, or heart diseases.


Maintaining stable blood sugar levels can help reduce the likelihood of chronic health issues, particularly heart disease and stroke. People with diabetes are at an increased risk of heart attack, making it crucial to manage blood sugar levels.


If you are concerned about your blood sugar levels, regularly getting a good night's sleep, avoiding eating late at night, and doing some exercise after dinner can greatly help your body use insulin effectively. If you have diabetes and consistently experience high blood sugar levels in the morning, talk to your doctor. Additional blood sugar testing or the use of a continuous glucose monitor may be necessary to determine the appropriate treatment, such as adjusting diabetes medication or daily exercise.


In conclusion, just as healthy eating and regular exercise are essential for a healthy body, sleep also plays a crucial role in maintaining healthy blood sugar levels.
