Topics: sleep disorders, Type 2 diabetes, Insulin resistance, Blood sugar control, Sleep quality, Diabetes management & Sleep science



Sleep and diabetes have a complex, bidirectional relationship. Poor sleep can affect blood sugar control and insulin sensitivity, while diabetes symptoms can disrupt sleep patterns. Living with type 2 diabetes is a journey filled with challenges and lifestyle adjustments. As millions of individuals around the world grapple with this chronic condition, it's crucial to explore every fact of its management, including its relationship with an often-overlooked factor that is sleep. Let's understand the connection deeply:



Diabetes is a condition that affects the body's ability to regulate blood sugar levels effectively. It is characterised by insulin resistance or insufficient insulin production. Meanwhile, sleep is a fundamental aspect of our daily lives, impacting everything from cognitive function to overall well-being.

In this blog post, we'll delve into the intricate connection between sleep and type 2 diabetes. You'll discover the science behind this relationship, the factors that can disrupt your sleep when you have diabetes, and actionable steps to improve both the quality of your rest and your diabetes management.

Let's begin our journey to better health by exploring the basics of type 2 diabetes.


What Is Type 2 Diabetes?

Type 2 diabetes is a chronic metabolic disorder that affects how your body processes glucose, the primary source of energy for cells. To understand its connection with sleep, it's essential to grasp the fundamentals.

Common Symptoms of Type 2 Diabetes:

  • Frequent Urination: Individuals with diabetes may experience increased urination as their kidneys work to eliminate excess glucose from the bloodstream.
  • Increased Thirst: Frequent urination can lead to dehydration, causing excessive thirst.
  • Unexplained Weight Loss: Despite eating more, some people with diabetes may lose weight due to the body's inability to use glucose for energy.
  • Fatigue: The body's cells aren't receiving enough glucose, leading to feelings of tiredness and weakness.

The Importance of Quality Sleep

Quality sleep is a cornerstone of good health, and its significance cannot be overstated. In the next section, we'll explore the stages of sleep and their functions, shedding light on why sweet dreams are essential for a sweet life.

Sleep consists of several stages, including REM (Rapid Eye Movement) and non-REM stages. Each stage has a specific purpose in maintaining your physical and mental well-being. Here's a brief overview of several stages of sleep:

1. Non-REM Sleep: This stage is divided into three phases. Stage 1 and 2 are lighter stages of sleep, while Stage 3 is deep sleep. Non-REM sleep is essential for physical restoration and growth.

2. REM Sleep: REM sleep is associated with dreaming and plays a crucial role in cognitive function, memory consolidation, and emotional well-being.

The recommended amount of sleep for adults typically falls between 7-9 hours per night. However, individual needs may vary. Adequate sleep duration is vital for:

  • Cognitive Function: Sleep enhances memory, problem-solving abilities, and concentration.
  • Emotional Well-being: Quality sleep can improve mood and reduce the risk of mood disorders.
  • Physical Health: Sleep supports the immune system, promotes tissue repair, and regulates hormones involved in appetite and stress.


Sleep and Diabetes Relation

Sleep disturbances can lead to elevated stress hormone levels, which can affect insulin sensitivity and glucose regulation. Blood sugar and sleep shows some connection, means that individuals with diabetes who experience poor sleep may have a harder time managing their blood sugar levels effectively. Moreover, sleep deprivation can trigger cravings for high-carbohydrate, sugary foods, making it even more challenging for individuals with diabetes to control their diet and maintain stable blood sugar levels.


Blood sugar and sleep


Among individuals with diabetes, there is a notably higher prevalence of various sleep disorders, including:

  1. Sleep Apnea: This condition involves intermittent pauses in breathing during sleep, leading to reduced oxygen levels in the blood. Sleep apnea can be associated with insulin resistance and higher blood sugar levels.
  2. Restless Legs Syndrome (RLS): RLS can disrupt sleep due to uncomfortable sensations in the legs, leading to frequent movements. It has been linked to a higher risk of developing type 2 diabetes.
  3. Insomnia: Insomnia, characterised by difficulty falling asleep or staying asleep, can contribute to poor sleep quality and potentially worsen diabetes symptoms.

Understanding and addressing these sleep disorders is crucial for individuals with diabetes to improve their overall health and diabetes management.


Factors Influencing Sleep in Type 2 Diabetes

Several factors can disrupt sleep in individuals with type 2 diabetes, making it essential to address these issues to improve both blood sugar and sleep.

  1. Diet: Pay attention to your meal timing and composition. Eating large or high-carbohydrate meals too close to bedtime can lead to blood sugar spikes, making it challenging to fall asleep. Consider having a balanced dinner a few hours before bedtime and avoid caffeine or alcohol, which can interfere with sleep.
  2. Physical Activity: Regular exercise is beneficial for diabetes management and overall health, but timing matters. Exercising too close to bedtime can increase alertness and make it harder to fall asleep. Aim for at least 30 minutes of moderate-intensity exercise earlier in the day.
  3. Stress: Chronic stress and anxiety can interfere with sleep patterns. Stress management techniques such as meditation, deep breathing exercises, or mindfulness can help reduce anxiety and improve sleep quality.
  4. Nighttime Hypoglycemia: Low blood sugar (hypoglycemia) during the night can wake you up and disrupt your sleep. To prevent this, consider adjusting your evening insulin or medication doses with the guidance of your healthcare provider.

Managing Type 2 Diabetes Through Better Sleep


Managing Type 2 Diabetes Through Better Sleep


Improving sleep quality can positively impact type 2 diabetes management. Here are some practical tips and strategies to help you get better rest:

1. Establish a Consistent Sleep Schedule: Try to go to bed and wake up at the same time every day, even on weekends. Irregular sleep patterns can disrupt your body's internal clock, making it harder to fall asleep and wake up. Also, while short power naps can be refreshing, excessive daytime napping can interfere with nighttime sleep. If you need to nap, aim for a short nap of 20-30 minutes.

2. Create a Relaxing Bedtime Routine: The blue light emitted by phones, tablets, and computers can interfere with melatonin production, making it difficult to fall asleep. Aim to avoid screens for at least an hour before bedtime. Develop a calming pre-sleep routine to signal to your body that it's time to sleep. Activities like reading a book, taking a warm bath, or practising relaxation exercises can be helpful.

3. Optimise Your Sleep Environment: Investing in a comfortable mattress and pillows that support your preferred sleeping position can significantly enhance sleep quality. Ensure your bedroom is conducive to sleep. Consider blackout curtains to block out light, and use white noise machines or earplugs to minimise disruptive sounds.

4. Monitor Blood Sugar Levels: Consistently monitor your blood sugar levels and keep a log to track patterns. Share this information with your healthcare provider, who can adjust your diabetes management plan as needed. If you need a snack before bed to prevent low blood sugar during the night, opt for a balanced choice like a small amount of protein and complex carbohydrates.

By implementing these lifestyle adjustments and sleep hygiene practices, you can significantly improve both your sleep quality and your ability to manage type 2 diabetes effectively. Remember that the relationship between diabetes and sleep is bidirectional, meaning that better sleep can lead to better blood sugar control and vice versa.


Does diabetes make you tired

Yes, diabetes can make you feel tired due to factors like fluctuating blood sugar levels, with both hyperglycemia and hypoglycemia causing tiredness. Insulin resistance in type 2 diabetes also contributes to this fatigue. Frequent urination can cause dehydration, further increasing tiredness, while the stress and sleep disturbances associated with managing diabetes can significantly impact energy levels. 

The reasons of diabetes makes you tired are multifaceted:

  1. Hyperglycemia
  2. Hypoglycemia
  3. Insulin resistance
  4. Dehydration
  5. Stress
  6. Sleep disturbances
