Exploring How Light Therapy Can Help with Type 2 Diabetes

As we drift from the active summer months into the rigors of school and start seeing Fall on the horizon, we all start to feel the slow down.

This physical slowdown and refocusing on family and school often pulls us from the healthy eating habits and into eating out more often. Why do I bring this up? Because today I want to talk about Type 2 Diabetes and how it impacts so many of us - almost 1 out of 10 Americans!

What is Type 2 Diabetes?

First let’s get a clear understanding of what diabetes is and then the differences between the different types of diabetes. Both of these diseases can begin during childhood. However, older adults are more likely to experience Type 2 Diabetes.

Type 1 Diabetes is when your body's pancreas does not make insulin, because the body's immune system attacks the cells that produce this insulin.

Type 2 Diabetes is when the pancreas makes less insulin than it should which results in your body becoming resistant to insulin.

“Type 2 diabetes is a condition that happens because of a problem in the way the body regulates and uses sugar as a fuel. (Glucose) This long-term condition results in too much sugar circulating in the blood. Eventually, high blood sugar levels can lead to disorders of the circulatory, nervous and immune systems.” (Article 1.)

One thing that is very important to know is that there is no current cure for Type 2 diabetes. You can manage the disease with healthy lifestyle choices, however this only reduces symptoms.

What can lead to Type 2 Diabetes?

Type 2 diabetes is mainly the result of two problems (Referenced from Article 1):

  • Cells in muscle, fat and the liver become resistant to insulin. As a result, the cells don't take in enough sugar.

  • The pancreas can't make enough insulin to keep blood sugar levels within a healthy range.

Exactly why this happens is not known. It’s important to know that being inactive or overweight are both tied to Type 2 Diabetes and are seen as leading causes for it.

Referenced from Article 1.

  • Age

  • Inactivity

  • Overconsumption of sugar (Pre-diabetes)

  • Poor fat distribution

  • Family History

This can lead to…

  • Diseased heart & blood vessels

  • Nerve damage

  • Kidney disease

  • Eye damage

  • Skin conditions

  • Slow healing

  • Hearing impairment

  • Sleep apnea

  • Dementia

The core players when it comes to diabetes:


In your body, your pancreas produces the hormone insulin. This hormone regulates sugar and enables sugar to enter your cells while also communicating to your body how much sugar is in the bloodstream thereby having the pancreas release more or less insulin.


This alternative name for sugar, is what gives your cells the energy it needs for your muscles, tissues, and beyond. Glucose comes from your food and also from your liver. This is where insulin comes in and sees how much Glucose is in the bloodstream - allowing it to be incorporated into your cells. If you don’t have enough glucose, your liver will break down stored glycogen into glucose so you have enough in your body for energy.

What are the symptoms of Type 2 Diabetes?

Referenced from Article 1.

  • Increased thirst

  • Frequent urination

  • Increased hunger

  • Unintended weight loss

  • Fatigue

  • Blurred vision

  • Slow-healing sores

  • Frequent infections

  • Numbness or tingling in the hands or feet

  • Areas of darkened skin, usually in the armpits and neck

The biggest thing to be aware of is that maintaining a healthy lifestyle is the key to managing the disease as much as possible. Eating healthy, losing weight, and sustaining an active lifestyle is essential. This can also help to slow it’s progress.

How does light therapy help?

As with so many of the natural processes within your body, you want to focus on helping your body by eating clean and simple foods, exercising regularly (even a walk outdoors each day is helpful) and maintaining a healthy weight allows your body naturally regulate itself.

Light therapy will compliment these healthy lifestyle choices and help speed the process of healing along.

The blue, red and infrared lights all work together to actively increase circulation so your body can regulate and care for itself as it interacts with the different wavelengths of light.

During a session, light therapy helps your body devote energy to circulation, ATP production, and cellular healing which impacts your liver and pancreas, allowing your body to also regulate its hormones in a healthier way and reduce symptoms of Type 2 Diabetes (or help to prevent it.)

What does science say?

There are some really cool studies that are starting to be performed that show that near infrared light therapy helps to reduce inflammation and help your body gain more energy and better gut microbiota in general. This also helps to remediate the symptoms that occur with Type 2 Diabetes.

“In fact, recent in vitro and in vivo studies have demonstrated improvements in Insulin Resistance in skeletal muscle, adipose tissue, and hepatic cells mediated by PBMT (Photobiomodulation Therapy). Further, there is evidence that PBMT can potentiate exercise-induced improvement in Insulin Resistance through ameliorating mitochondrial dysfunction, reducing inflammation, and modulating oxidative stress. Moreover, reduced adiposity and altered gut microbiota also appear to mediate PBMT effects on Insulin Resistance. “ (Article 2.)

And again, Type 2 Diabetes is something that can’t be cured, but the work of light therapy is to reduce symptoms and lessen the impact of the disease on your life.
