Having trouble sleeping? And then waking up to find your blood sugar has gone haywire?

You’re definitely not alone! A lot of us might not know, poor sleep can negatively affect diabetes.

No, you don’t need to jump to these sleeping pills. Getting a good night’s sleep is possible without any medications.

First, let’s understand the simple science behind why sleeping better can help you manage your diabetes better.

What is the Connection Between Sleep and Blood Sugar Levels?

To understand this, you’ll first need to understand the relationship between insulin and blood sugar.  

When we eat, our body turns the food into glucose, a type of sugar we use for any activity like standing, talking, moving around, or even just sitting.

Now enters Insulin’s role. Insulin is the hormone that helps the sugar go from our blood into our body cells to be used up.

But sometimes, our body doesn’t listen to insulin well, making it hard for sugar to get into our cells. This problem is called insulin insensitivity, which can make our blood sugar levels too high.

So, how does sleep help control your blood sugar levels & diabetes?

A good night’s sleep makes our body listen to insulin better. When we’re well-rested, the cells in our body are more willing to let sugar in, which ultimately helps keep our blood sugar at a healthy level.

That’s why sleeping well is important for controlling blood sugar and managing diabetes.

However, this process gets disturbed when we don’t get enough sleep.

Did You know

Can Poor Sleep Increase Your Blood Sugar Levels?

YES! Less sleep or poor quality sleep can totally affect your blood sugar level and, therefore, your Diabetes. How? 

So, when you don’t get enough hours of sleep, or your sleep is very disturbed, it makes your body less sensitive to insulin.

And when insulin is not able to do its job well it is not able to move the glucose in our bloodstream to the cells – which means more sugar remains in the blood. And more sugar in the blood = high blood sugar levels.

This is why poor sleep is often linked to an increased risk of type 2 diabetes.

And high blood sugar and poor sleep  are like a vicious cycle. One leads to the other. So, the best way to break this cycle is by doing something simple – SLEEP WELL!

Here are a few clinically validated strategies to help you sleep better at night:

Here’s a simple plan to help you sleep better at night:

Easy 8-Step Plan for Better Sleep

There are simple and easy techniques that fall under Sleep Hygiene, a collection of practices aimed at ensuring good nighttime sleep quality and full alertness during the day. You can give it a try once:

1. Creating a Healthy, Restful Routine – Dinner Time Habits:

  • Set regular dinner times.
  • Make mealtime a family time.
  • Enforce a ‘no devices at the dining table’ rule for everyone.
  • Engage in communication, sharing, and laughter.

2. The Bedroom: Remember the 3 Cs – Cool, Comfortable, and Clean

  • Adjust your bedroom temperature to what feels best for you, considering the weather.
  • Ensure mattresses and pillows are firm, supportive, yet comfortable.
  • Keep the bedroom clutter-free and smelling fresh, using essential oils or air humidifiers if needed.

3. Lighting

  • Switch to dim or warm lighting in the evenings. Bright lights can disrupt your circadian rhythm, making it hard to sleep at the ideal time.

4. Minimize Screen Exposure

  • Disconnect from devices at least 30 minutes before bedtime. Screens can keep your brain alert, preventing it from transitioning to rest mode.
  • Set your alarm for the next day, then set your phone aside and practice relaxation techniques.

5. Limit Alcohol and Caffeine Intake

  • Avoid caffeine 1-2 hours before bedtime, as it can keep you awake.

6. Engage in Physical Self-Soothing

  • Taking a bath or washing your face, feet, and hands 30 minutes before bedtime can help you cool down and relax.

7. Relaxation Techniques

  • Breathing Exercises: Try deep breathing, diaphragmatic breathing, or box breathing before bed to regulate breathing, calm the nervous system, and reduce stress.
  • Progressive Muscle Relaxation: Helps relax your muscles and control stress and anxiety.
  • Humming: Relax facial, neck, and shoulder muscles to fall asleep faster.

8. Sleep Journal

  • Keeping a sleep journal to note your sleep duration and disturbances can help identify what affects your sleep quality. Use this information to better manage your sleep.

Need One More Reason to Sleep Well?

When people don’t sleep well enough, they often feel tired and might eat more sugary foods to get energy. This can lead to weight gain leading to obesity, which increases the risk of diabetes.

Now, don’t steal those desserts from your fridge during the night!!

How Much Sleep Do You Really Need?

Figuring out how much sleep you need can be tricky. Most adults need between 7 to 9 hours of sleep.

But it can depend on each individual. What matters more than the sleep hours itself is the QUALITY OF SLEEP.

So, rather than counting your sleep hours, aim at getting good quality, undistubed sleep for 7-9 hours every night. This is all the more imporatnt if you have pre-diabetes or diabetes or are trying to lose weight.

How Can Technology Improve Your Sleep and Diabetes Management?

Before talking about this just ask yourself if that one more episode of your favorite web series is more important than your health? 

We know your answer!

  • Technology, specifically Continuous Glucose Monitors (CGM) and fitness bands, significantly enhances diabetes and sleep management. CGMs offer real-time blood sugar monitoring for immediate lifestyle or diet adjustments.
  • Meanwhile, fitness bands track sleep patterns, identifying disruptions and guiding towards better sleep habits. Together, these tools provide a holistic view of your health, empowering you to make informed decisions for improved well-being.
  • Skipping that extra episode for more rest or fine-tuning your daily habits can have a HUGE IMPACT on managing diabetes effectively.

We hope, this article helped you understand the importance of sleep especially if you are controlling diabetes.
