How Are Blood Sugar and Sleep Connected?


We all know getting a good night's sleep is essential for our well-being. However, many people need to realize just how crucial sleep is for various aspects of health and functioning. Quality sleep is vital for physical health, cognitive performance, emotional regulation, and long-term disease prevention. It allows the body to repair and regenerate tissues, maintain a healthy heart, and manage weight. Furthermore, sleep enhances memory, attention, and mood while reducing the risk of chronic conditions like diabetes and cardiovascular disease. Yet, despite its importance, many factors can disrupt sleep, including lifestyle habits, psychological stress, medical conditions, and environmental influences. One often overlooked factor is blood sugar levels, specifically low blood sugar levels, which can significantly impact sleep quality and duration. This blog will explore the multifaceted relationship between sleep and blood sugar, offering practical tips and supplement recommendations to help you achieve better sleep by managing your blood glucose levels effectively. Additionally, we will discuss the critical role of blood glucose levels in controlling your sleep and overall health, particularly sleep deprivation, and its effects on blood sugar and poor sleep quality.

The Crucial Role of Sleep

Why Sleep is important:

Physical Health

  • Healing and Repair: When you sleep, your body fixes tissues, muscles, and bones. It helps heal wounds and strengthens your immune system so you won't get sick quickly.
  • Heart Health: Sleeping well means a lower chance of getting heart problems or high blood pressure. Your heart and blood vessels get to rest, too, when you're asleep.
  • Keeping Weight in Check: Not sleeping enough can cause weight gain because it interferes with the hormones that tell you when you're hungry or full, making you want to eat more.
  • Balance of Hormones: Sleep helps control many different hormones, including those that help you grow and deal with stress.

Cognitive Function

  • Remembering and Learning: Sleep helps you remember what you learn and be creative. When you're sleeping, your brain organizes everything you've learned.
  • Paying Attention: When you've had enough sleep, you can focus better and make good decisions. If you're tired, everything seems much more complicated.
  • Mood: Getting enough sleep makes you less cranky and in a better mood. If you don’t sleep well, you might feel up and down and even get anxious or sad.

Performance and Safety

  • Doing Great in Sports: Sleep makes you faster, stronger, and more coordinated, whether you play sports or exercise.
  • Staying Safe: If you sleep well, you're more alert and less likely to get hurt because you're paying attention. If you're sleepy, you could make mistakes that could cause accidents.

Long-Term Health

  • Keeping Away Long-term Illnesses: Good sleep over time can make it less likely for you to get diseases like diabetes, heart disease, or even some types of cancer.
  • Fighting Off Germs: When you sleep, your body's defense system strengthens, making it easier to beat germs and stay healthy.

Factors Contributing to Poor Sleep

There are many reasons why people might not sleep well. These reasons can include how they live, like eating junk food or looking at screens before bed, feeling worried or stressed, having health problems, or being in a place that's too loud or bright at night. Here are some common factors that can contribute to poor sleep: cognitive behavioral therapy (CBT), which is a first-line treatment for insomnia, lifestyle changes, restless leg syndrome (RLS) due to an iron deficiency or high blood glucose levels, circadian rhythm disruptions, and other sleep disorders such as obstructive sleep apnea. These factors, including RLS and circadian rhythm disruptions, should be addressed to improve sleep quality.

Lifestyle Factors

  • Sleeping at Different Times: When you don't go to bed and wake up at the same time every day, your body's clock gets mixed up, and you might have trouble falling asleep or waking up when you want to.
  • Caffeine and Other Wake-Up Things: Drinking soda, coffee, or tobacco near bedtime can keep your brain too active to sleep.
  • Not-So-Cozy Bedrooms: A not-so-cozy bed, too much light, loud sounds, or a room that's too hot or cold can make it challenging to sleep well.
  • Looking at Screens Before Bed: The light from electronic gadgets like phones and tablets can trick your brain into thinking it's still daytime, making it hard to feel sleepy.

Psychological Factors

  • Stress and Worry: If something's bothering you, it can make your brain stay awake trying to figure it out instead of letting you sleep.
  • Feeling Sad: People dealing with sadness might find it hard to sleep well or too much.
  • Too Many Thoughts: If your mind keeps reviewing things repeatedly, it's like your brain doesn't know it's time to rest.

Medical Conditions

  • Sleep Problems: Some people have specific sleep issues that make it hard to sleep well, like sleep apnea or restless legs.
  • Pain: If you're in pain, such as from a back injury or headache, it's tough to stay asleep.
  • Tummy Troubles: Heartburn can make you uncomfortable and wake you up.
  • Hormone Changes: At certain times, like when growing up, having a baby, or during monthly cycles, changes in your body can mess with your sleep.

Environmental Factors

  • Working Weird Hours: People who work at different hours, especially at night, can have a hard time getting enough sleep to match their schedule.
  • Traveling Across Time: Going to new places in different time zones can confuse your body, and you might not feel sleepy when it's actually bedtime.
  • Busy Homes: Living somewhere with lots of noise, sharing your space with many people, or having a baby who wakes up a lot can all make it harder to sleep through the night.

Blood Sugar and Sleep

Did you know that if your blood sugar isn't suitable, it can make it harder for you to sleep? When your blood sugar is too high or too low, it can cause sleep problems. Here's what can happen:

Effects of High Blood Sugar (Hyperglycemia)

  • You might have to go to the bathroom often at night, which can wake you up many times.
  • You can get thirsty, and your mouth might feel dry. This might wake you up because you need a drink of water.
  • Your body might feel too restless to sleep well.
  • If your blood sugar has been high for a long time, it might hurt your nerves. This can make your arms or legs feel tingly or painful, keeping you awake.

Effects of Low Blood Sugar (Hypoglycemia)

  • You might sweat a lot while sleeping, which can wake you up because it doesn't feel nice.
  • You could wake up hungry because your body needs more sugar.
  • You might feel nervous or shaky, which can stop you from falling asleep quickly.
  • It can even mess with your dreams and deep sleep, which helps your brain remember things.

Diabetes and Sleep Disorders

  • Some people with diabetes might snore a lot or stop breathing for short times while they're asleep. This is called sleep apnea, and it can make you tired during the day.
  • Diabetes can also make some people feel like they have to wiggle their legs a lot at nighttime, which can make it hard for them to fall asleep or stay asleep.

Managing Blood Sugar for Better Sleep

Blood sugar levels can significantly impact our sleep quality, but there are effective strategies to manage this:

Regular Monitoring: Consistently checking blood sugar levels to maintain them within the desired range can mitigate the sleep disturbances caused by high or low levels.

Healthy Diet: A balanced diet with regular meal times aids in stabilizing blood sugar levels. For better sleep, avoiding heavy, sugary, or caffeinated foods and drinks before bedtime is also wise.

Exercise: Regular exercise contributes to balanced blood sugar levels and can enhance sleep quality. Aim for mild to moderate activities, particularly in the evenings, to avoid stimulating the body too much before sleep.

Supplement Management: Adhering to prescribed supplements and discussing any sleep-related concerns with a healthcare professional can offer dual benefits for managing blood sugar and sleep quality.

Supplements for Balancing Blood Sugar

If you want to keep your blood sugar levels healthy, consider adding supplements. One great choice is chromium.

Why Upgraded Chromium?

Chromium is a unique mineral that helps your body manage blood sugar levels. Here's how it helps:

  • Boosts Insulin Work: Insulin is a hormone that helps your body use sugar from food for energy. Chromium makes insulin work better so your body can keep your blood sugar levels steady.
  • Helps with Sugar Use: Chromium helps your body use sugar more effectively. This means your body can avoid sugar highs and lows, keeping things balanced.

How Does Chromium Help with Diabetes?

  • Type 2 Diabetes: Research shows that people with type 2 diabetes might have better blood sugar control if they use chromium supplements. It might even help them use less medication.
  • Gestational Diabetes: For women with diabetes during pregnancy, chromium could help keep their blood sugar levels in check.

How Does Chromium Work?

  • Chromodulin: This compound in your body works with insulin to help sugar move into your cells, where it's used for energy.
  • Helps Insulin Work Better: Chromium also ensures insulin and its receptors work well together. This is important because it allows more sugar to enter cells, lowering blood sugar levels.

Adding chromium to your diet might be an excellent way to help control your blood sugar, especially if you’re dealing with diabetes or at risk for it. Talking to a doctor before starting any new supplement is always a good idea.

Why Upgraded Magnesium?

Magnesium is essential for your body because it helps with many things, including keeping your blood sugar levels right. Here's how magnesium does its magic for blood sugar:

Insulin Sensitivity and Secretion

  • Boosts Insulin Sensitivity: Magnesium makes insulin, a hormone, work better. Insulin helps sugar in the blood get into the cells used for energy. When insulin works better, your blood sugar levels stay more balanced.
  • Helps with Insulin Production: Your pancreas makes insulin, and magnesium helps make sure it's doing its job right. This means your body can react better when your blood sugar goes up.

Cellular Glucose Uptake

  • Helps Sugar Transporters: Magnesium helps the "doors" (or transporters) that let sugar move from your blood into your cells work better, keeping your blood sugar levels healthy.
  • Turns Sugar into Energy: Magnesium is a helper for different reactions in your body that turn sugar into energy. This way, sugar doesn't just hang around in your blood.

Role in Diabetes Management

  • Lowering Risk of Type 2 Diabetes: People who get a lot of magnesium from their diet might have a lower chance of getting type 2 diabetes. And if someone already has diabetes, magnesium might help them manage their blood sugar better.
  • Fighting Insulin Resistance: If your body's cells aren't responding to insulin well (which means you have insulin resistance), magnesium might help make them listen better, which can lower your blood sugar levels.

Mechanisms of Action

  • Helps Enzymes Work: Magnesium is needed for enzymes that break down sugar and turn it into energy. This helps keep your blood sugar under control.
  • Fights Inflammation and Stress in the Body: Magnesium can reduce inflammation and protect cells from damage (oxidative stress). Since inflammation and anxiety can make it harder for insulin to work right, magnesium helps keep things running smoothly.

Adding magnesium to your diet can help manage your blood sugar, especially if you're concerned about diabetes or insulin resistance. Remember, talking to a doctor before starting any new supplement is always wise.

Why Upgraded Potassium?

Potassium is an essential mineral your body needs to keep everything running smoothly, including steady blood sugar levels. Let's talk about what potassium does to help with blood sugar:

Insulin Function and Secretion

  • Boosting Insulin Sensitivity: Potassium improves your body's use of insulin, a hormone that helps control blood sugar. When your body uses insulin well, sugar can more easily get into your cells, which helps keep your blood sugar from getting too high.
  • Helping Make Insulin: Potassium is essential for the cells in your pancreas that make insulin. It helps ensure these cells can do their job when your blood sugar changes so you get the right amount of insulin when needed.

Cellular Glucose Uptake

  • Keeping Things Balanced: Potassium is part of a group of minerals called electrolytes that help keep the water and minerals in your cells balanced. This balance is key for cells to work right, including taking in sugar.
  • Moving Sugar into Cells: Potassium helps proteins called glucose transporters move sugar from the blood into the cells, which is essential for keeping blood sugar at a good level.

Role in Preventing and Managing Diabetes

  • Lower Chance of Type 2 Diabetes: Eating foods with a lot of potassium may help lower your chance of getting type 2 diabetes. Potassium is good for keeping your blood pressure healthy and making it less likely for you to get insulin resistance, which can lead to diabetes.
  • Fighting Insulin Resistance: If your body isn't responding to insulin like it should (that means you have insulin resistance), not having enough potassium might be part of the problem. More potassium might make your cells listen to insulin better, which can help your blood sugar levels stay normal.

Mechanisms of Action

  • Keeping Beta Cells Happy: Potassium is involved in how the beta cells in your pancreas work. These cells must do the right thing when blood sugar levels go up by releasing insulin.
  • Muscle Power: Potassium helps your muscles contract and relax correctly, which is good for overall metabolism. Strong muscles that work well help you stay active, which helps keep your blood sugar in check.

So, including foods with potassium in your diet can help your body manage blood sugar better, whether you're trying to prevent diabetes or you're working to control it. But remember to talk to your doctor about how much potassium you need, especially if you're considering taking supplements.


In conclusion, if you're having trouble sleeping, it might be because of your blood sugar levels. When your blood sugar is too high or too low, it can make sleeping hard.

Managing your blood sugar with a healthy diet, regular exercise, and the right supplements like chromium, magnesium, and potassium can help you get better sleep. Always remember to talk to your doctor before starting any new supplements. Taking care of your blood sugar can significantly affect your sleep and overall well-being.
