Harness the power
of hot & cold therapy
in your recovery routine
For centuries, healthcare practitioners across cultures have utilized heat and cold therapy to treat injuries and illnesses. This timeless technique has also gained popularity among elite athletes and celebrities seeking to optimize their recovery.
But what makes thermal therapy so effective in accelerating the body's natural healing process?
Contrast Therapy - Combining heat & cold Therapy
Effect of thermal therapy on blood vessels (Vasodilation and vasoconstriction)
Heat increases the temperature of the blood vessels, causing the smooth muscle cells in the vessel walls to relax. This relaxation leads to an increase in the diameter of the blood vessels, allowing for more blood flow (vasodilation), which speeds up the delivery of oxygen and nutrients that are essential for repair & recovery.
Heat can also aid recovery in other ways, such as reducing pain (by blocking pain signals to the brain), reducing stiffness and increasing flexibility.
Conversely, cold temperatures cause the smooth muscle cells in blood vessel walls to contract, leading to a decrease in blood vessel diameter and a reduction in blood flow (vasoconstriction).
This allows for reduced inflammation and swelling in the short term during the acute phase of an injury.
Contrast Therapy - Combining both heat & cold therapy
“Wouldn’t cold therapy create a counter-intuitive effect that would impede recovery?”
The reason why contrast therapy works is that when we alternate between heat and cold therapy, there is a rebound effect that causes the blood vessels to dilate or constrict even more than they would otherwise have if only one therapy was used.
When both therapies are combined over multiple cycles, the constant switch between heat and cold creates a “pumping” effect that reduces inflammation, improves blood circulation, relaxes the muscles and stimulates lymphatic drainage.
HYDRAGUN’s
Contrast Therapy Bundle
with the Supertub Cold Plunge
& HeatPod Sauna Blanket
Contrast therapy has long been the secret to faster recovery and improved performance, reserved for elite athletes and celebrities.
However, accessing this powerful tool has been a luxury only a few could afford, with pricey wellness spas and centers being the only option.
That's all about to change. We're excited to introduce HYDRAGUN's Contrast Therapy Bundle, making this cutting-edge technology accessible to everyone.
For just $2999, you'll get not one, but two recovery devices:
- The Supertub Cold Plunge for cold water immersion
- The HeatPod Sauna Blanket for heat therapy
With the Contrast Therapy Bundle, you can unlock the full potential of contrast therapy from the comfort of your own home.
How to use the Supertub Cold Plunge & HeatPod Sauna Blanket
There’s no definitive way to use contrast therapy as part of your recovery protocol because our bodies are all different. However, we would like to suggest 2 ways to implement contrast therapy:
- Using it at different times of the day, multiple times a week
- Alternate between both devices in a single session.
Contrast therapy at different times of the day
Cold exposure has the effect of stimulating your body with a dopamine rush. It’s great for waking yourself up early in the morning and stimulating your parasympathetic nervous system.
On the other hand, heat exposure has the effect of relaxing your muscles, relieving stress and anxiety, and promoting melatonin production as your body cools off post-sauna session.
Therefore, we recommend using the Supertub Cold Plunge early in the morning, within 1 hour of waking up, and the HeatPod Sauna Blanket late in the evening, approximately 1-3 hours before bedtime.
Contrast therapy daily schedule
07:00 - Waking up
Waking up with sunrise helps regulate your circadian rhythm as morning light exposure:
- ⏰ Resets the internal body clock
- ☕️ Boosts alertness & energy
- 🧠 Enhances mental clarity
07:15 - Cold plunge
Try to cold plunge within 30 minutes of waking up. 2-5 min of cold plunging early in the morning can help with:
- ⚡️ Adrenaline release - increasing alertness & energy
- 💡 Dopamine release - improve mood & motivation
- 🧠 Nerve stimulation - increase electrical activity in the brain
21:30 - Sauna
20 min of sauna at 65-90°C (149-194°F) can help with:
- 💆 Promotes relaxation (by stimulating the parasympathetic nervous system)
- 😴 Melatonin regulation - induces sleepiness
- ☯️ Decrease cortisol and adrenaline, calming the body
23:00 - Bedtime
For consistent quality sleep, we recommend having a wind down routine.
- 📵 Reduce exposure to screen-time and blue-light 1-2 hours before bedtime which can inhibit melatonin production
- ❄️ Keep bedroom temperature at 18-23°C (64-73°F) for optimal sleep
Contrast therapy in a single session
Using both therapies in the same session can help boost recovery by creating the “pumping” effect in your blood vessels.
How to use the Supertub and HeatPod in the same session
Step 1: Use the HeatPod Sauna Blanket for 15-30 min at 70-85°C (158-185°F). Ideally you should be starting to sweat quite a bit.
Step 2: Rinse off your sweat
This is to keep the water in your cold plunge tub clean for longer so that you don’t need to change
it as often
Step 3: Dip your body into the Supertub Cold Plunge for 2-5 min at 4-10°C (39-50°F)
Over time, a thin, insulating barrier (Thermal Barrier) forms just above your skin, making the
effects of cold exposure less effective. Try moving your hands around to break it so that you will
continue to feel cold.
Step 4: Wipe yourself dry with a towel
Repeat Steps 1-4 for 1-3 sets.
