Diabetes and sleep: how to get better rest?

When managing type 2 diabetes, the focus is often on factors like diet, exercise, and medication. Sleep is often overlooked, yet it plays a crucial role in regulating blood sugar levels.¹ Understanding the connection between sleep and diabetes is important, as it reveals how better sleep can help people with type 2 diabetes manage blood sugar levels.

People with diabetes frequently face sleep problems, including insufficient sleep, obstructive sleep apnea, and insomnia, making it harder to control blood sugar levels.^1–3  Factors that may contribute to sleep disorders include:⁴

• Peripheral neuropathy — weakness, numbness, or pain in the hands and feet
• Restless legs syndrome
• Fluctuating blood sugar levels
• Nocturia — frequent urination at night
• Depression

Understanding and addressing these factors can help improve sleep quality. Here are some ideas to help you start making changes to your routine that will improve your sleep.

As you may have experienced, poor sleep quality and a late bedtime can lead to elevated blood sugar levels after breakfast the next morning.⁵ Getting good, uninterrupted sleep is important to keep your blood sugar at healthy levels. It can also improve how your body handles blood sugar after meals.

Making small, intentional changes to your daily routine can improve your sleep hygiene and help you achieve a restful night's sleep.⁴ These changes may also help with sleep disorders or irregular sleep patterns.

Get cozy

Exercising, doing chores, or running errands right before bed can actually wake you up and make it more difficult to fall asleep. Try to complete these tasks at least one hour before going to bed. 

Engage in relaxing activities such as reading a book, taking a warm bath, or practicing breathing exercises. This change in pace signals to your body that it is time to go to sleep.

Go to bed on time

A consistent bedtime is an important part of establishing a routine.⁴ Do your best to go to bed at the same time every day, even on the weekends, if you can. Avoid napping late in the day, as this can disrupt your sleep patterns and make it challenging to get a good night's rest.

Watch what you eat or drink

What you eat before sleep actually matters.⁴ It’s good practice to avoid heavy meals right before bedtime, as well as alcohol or caffeine. In fact, limit your fluid intake to at least one hour before bedtime so you won’t have to wake up in the middle of the night to use the bathroom. Just in case, use the bathroom right before bed as well.

Minimize stress

If you feel as though stress and anxiety interfere with your ability to relax and rest, discovering effective ways to manage them is key.

Stress can significantly impact your ability to get a good night's rest. If you find yourself feeling stressed or anxious, relaxation techniques such as meditation or journaling can be a helpful way to recenter and refocus your energy.

Set up your environment

A comfortable room can make it easier to fall asleep. Ensure the temperature is neither too hot nor too cold, and that the environment is quiet and dark. If you use your bedroom for work or to watch television, you may want to consider adjusting your setup, as these activities can be distracting.⁶

And as much as you love your pets, they can interrupt your sleep. If you have allergies, try to keep them off the bed (or out of your room altogether). Diabetes-alert dogs are excluded, of course.

Keep an eye on your blood sugar

Start the habit of checking your blood glucose one hour before bedtime.⁷ Doing this allows you to monitor how your body responds to the day’s activities, meals, and medications, which gives you insight into your nighttime blood sugar levels.

Additionally, high blood sugar can affect your sleep quality.⁸ With this in mind, you may also want to experiment with bedtime snacks that can help keep your blood sugar at normal levels overnight. Before making any changes to your routine, consult with your healthcare provider about your bedtime habits and blood glucose levels.

Improving sleep quality is essential for people with diabetes to manage their blood sugar levels effectively.¹ A consistent bedtime routine and improving your sleep hygiene may help you with any sleep problems or disorders you may have, allowing you to finally get some much-needed rest. 

Be sure to consult with your doctor or healthcare team to determine if there are any steps you can take to improve your sleep at night.
