Cold or sauna can improve metabolism, cardiovascular and brain health, balance hormones, and decrease inflammation. – Dr Andrew Huberman

At Encore Pilates, we’re committed to empowering you to live your healthiest life through holistic wellness practices. For those managing diabetes, innovative approaches like contrast therapy—combining infrared sauna and cold plunge—offer a powerful way to support your wellbeing. Backed by science and expert insights, this article explores how these therapies can benefit diabetes management, how to use them safely, and key precautions to consider.

The Power of Contrast Therapy

Contrast therapy involves alternating between heat (infrared sauna) and cold (cold plunge) to stimulate physiological responses that enhance circulation, reduce inflammation, and promote metabolic health. For people with diabetes, this dual approach may amplify benefits compared to using either therapy alone, as it challenges the body’s regulatory systems in a controlled way.

Infrared Sauna: Warming Your Way to Wellness

Infrared saunas use light wavelengths to deliver gentle, penetrating heat, typically at 40-60°C, promoting relaxation and detoxification. Peer-reviewed studies highlight their benefits for diabetes:

  • Blood Glucose Regulation: A 2010 study in The Journal of Alternative and Complementary Medicine found that far-infrared sauna therapy improved insulin sensitivity and reduced fasting blood glucose in type 2 diabetes patients. Heat stress mimics mild exercise, enhancing glucose uptake.

  • Improved Circulation: Research in Diabetes Care (2006) showed that infrared saunas enhanced blood flow and vascular function, reducing risks of neuropathy and cardiovascular issues common in diabetes.

  • Stress Reduction: A 2018 study in Evidence-Based Complementary and Alternative Medicine noted that sauna therapy lowered cortisol levels, helping to stabilise blood sugar by reducing stress.

Dr. Andrew Huberman, a neuroscientist, notes that infrared light supports mitochondrial function, which may improve metabolism in diabetes. He recommends 57 minutes of sauna exposure per week at a temperature that’s “uncomfortable but safe” for metabolic benefits.

Cold Plunge: A Cool Boost for Health

Cold plunge involves brief immersion in cold water (typically 10-15°C) to stimulate the body’s stress response and recovery mechanisms. Emerging research and expert insights suggest benefits for diabetes:

  • Insulin Sensitivity: A 2020 study in Frontiers in Physiology found that cold exposure increased insulin sensitivity by activating brown adipose tissue, which burns glucose for heat. This may help regulate blood sugar in type 2 diabetes.

  • Inflammation Reduction: Chronic inflammation exacerbates diabetes complications. A 2019 study in Journal of Physiology showed that cold water immersion reduced inflammatory markers, potentially easing diabetes-related inflammation.

  • Mood and Resilience: Cold exposure triggers endorphin release, improving mood and stress resilience, which can indirectly support blood sugar control. Dr. Gabrielle Lyon, a functional medicine expert, highlights cold therapy’s role in building mental and physical resilience, key for chronic disease management.

Dr. Huberman recommends 11 minutes of cold exposure per week, split into 2-3 sessions at 10-15°C, to boost metabolism and insulin pathways. He advises keeping sessions brief (1-3 minutes) to avoid overstress. Joe Rogan, a wellness advocate, praises cold plunges for recovery and mental clarity, noting their invigorating effects on his podcast.

Contrast Therapy: The Best of Both Worlds

Combining infrared sauna and cold plunge creates a synergistic effect. The heat dilates blood vessels, while cold constricts them, enhancing circulation and oxygen delivery. A 2021 study in International Journal of Environmental Research and Public Health found that contrast therapy improved vascular function and reduced blood pressure, both critical for diabetes management. The alternating stimuli may also enhance glucose metabolism by activating heat-shock and cold-shock proteins, as noted in a 2023 review in Metabolism.

David Goggins, known for extreme wellness practices, uses contrast therapy to push physical limits while stressing safety. His approach underscores the importance of listening to your body during these therapies.

How to Use Contrast Therapy for Diabetes

Sunlighten, a leader in infrared sauna technology and providers of our saunas, and health experts provide guidance on integrating these therapies safely. Here’s how to get started:

Infrared Sauna

  • Temperature: 45-55°C (gentle for diabetes patients).

  • Duration: Start with 15-20 minutes, 1-2 times per week. Gradually increase to 20-30 minutes, 3-4 times per week, as tolerated, per The Journal of Alternative and Complementary Medicine (2010).

  • Frequency: Aim for 57 minutes total per week, as Huberman suggests, split across sessions.

  • Tips: Stay hydrated, use a timer, and exit if lightheaded. Sunlighten saunas offer customizable wavelengths for optimal benefits.

Cold Plunge

  • Temperature: 10-15°C, as recommended by Huberman for metabolic benefits.

  • Duration: 1-3 minutes per session, 2-3 times per week, totaling 11 minutes weekly. Start with 30-60 seconds if new to cold exposure.

  • Frequency: Spread sessions across the week to avoid overstimulation, per Huberman’s protocol.

  • Tips: Submerge up to the neck, breathe steadily, and warm up gradually afterward (e.g., with a towel or warm shower).

Contrast Therapy Protocol

  • Sequence: Start with 15-20 minutes in the infrared sauna, followed by a 1-2 minute cold plunge. Repeat 1-2 cycles if comfortable, ending with cold for recovery or heat for relaxation.

  • Frequency: 2-3 sessions per week, combining both therapies. A 2021 study suggests 2-4 contrast sessions weekly for vascular benefits.

  • Tips: Allow 1-2 minutes between sauna and plunge to adjust. Monitor blood sugar before, during, and after sessions, as heat and cold can affect glucose levels.

Dr. Lyon advises consistency, integrating contrast therapy with nutrition and movement (like Pilates) for holistic diabetes management.

Contraindications and Safety Tips

Contrast therapy is generally safe but requires caution for people with diabetes:

  • Consult Your Doctor: Seek medical clearance, especially if you have neuropathy, cardiovascular disease, or unstable blood sugar. Both therapies can affect blood pressure and glucose levels.

  • Monitor Blood Sugar: Heat may cause hypoglycaemia, while cold can increase adrenaline, affecting glucose. A 2013 study in Experimental and Clinical Endocrinology & Diabetes noted hypoglycaemia risks with heat stress. Check levels before and after sessions.

  • Hydration: Diabetes increases dehydration risk. Drink water before, during, and after sauna and plunge sessions to prevent dizziness or electrolyte imbalances.

  • Temperature Sensitivity: Neuropathy may reduce heat or cold sensation. Use timers and avoid extreme temperatures (sauna >60°C, plunge <10°C).

  • Medication Interactions: Insulin or sulfonylureas may increase hypoglycaemia risk in heat or cold. Discuss adjustments with your doctor.

  • Contraindications:

    • Sauna: Avoid if you have severe cardiovascular disease, recent heart attack, or heat-sensitive conditions (e.g., multiple sclerosis). Pregnant women and those with implanted devices should consult a doctor.

    • Cold Plunge: Avoid if you have Raynaud’s disease, severe hypertension, or open wounds. Cold can trigger vasoconstriction, risky for unstable heart conditions.

    • Contrast Therapy: Not suitable for those with severe autonomic dysfunction or inability to tolerate rapid temperature changes.

  • Listen to Your Body: Exit immediately if you feel dizzy, nauseous, or short of breath. Goggins’ philosophy of respecting limits applies here.
