Cold plunge therapy can improve sleep by regulating core body temperature and signaling the body to rest. The post-immersion cooldown mimics the natural pre-sleep temperature drop, making it easier to fall and stay asleep. Cold exposure also lowers cortisol, activates the parasympathetic system, and boosts mood-enhancing neurotransmitters like dopamine and norepinephrine, promoting relaxation and mental calm. For best results, plunge 2–3 hours before bedtime to allow your body to wind down naturally.

Cold is Medicine
Cold plunge therapy involves immersing the body in cold water (5–10°C) to stimulate natural healing, reduce inflammation, improve circulation, and boost endorphins. It supports muscle recovery, strengthens the immune system, and enhances mental clarity—making it ideal for both physical and mental wellness.
At our Lethbridge wellness clinic, you can book a cold plunge session alone or combine it with an infrared sauna for contrast therapy, amplifying the benefits of both. Sessions take place in a private room with a shower, providing a clean, comfortable, and calming environment for beginners and experienced cold therapy enthusiasts alike.
How can cold plunging help me?
Feeling stressed, burnt out, or in need of an immune boost? The cold plunge revitalizes your body and mind, leaving you energized, clear-headed, and refreshed!

Cold plunge therapy may support individuals with ADHD by regulating the nervous system and enhancing focus. The cold exposure triggers the release of dopamine and norepinephrine, boosting attention, mood, and alertness. It also promotes mindfulness and body awareness, helping manage restlessness and improve emotional regulation—offering a natural way to increase mental clarity and energy.
Cold plunge therapy helps manage anxiety and stress by resetting the nervous system and promoting calm. Immersion triggers deep, controlled breathing and activates the parasympathetic system, lowering cortisol and restoring balance. Many people feel mentally refreshed, emotionally grounded, and more resilient after a session, making cold plunging a natural way to support mood and stress relief.
Cold plunge therapy can enhance workouts by boosting recovery, reducing muscle soreness, and improving mental resilience. Post-exercise immersion decreases inflammation, flushes out lactic acid, and speeds up muscle repair. It also stimulates the nervous system, increasing alertness, circulation, and energy. The mental challenge of cold exposure builds focus, stress tolerance, and toughness, supporting better performance. For best results, plunge after workouts for recovery or before for a quick pre-workout boost.
Cold plunge therapy supports the immune system by stimulating the body’s natural defenses. Cold exposure activates the circulatory and lymphatic systems, flushes out toxins, and boosts white blood cell production. Regular sessions can reduce inflammation, build resilience, and improve overall immune function. Pairing cold plunges with wellness practices like infrared sauna enhances these benefits, helping your body stay healthy and strong.
Cold plunge therapy strengthens mental resilience by challenging focus, breath control, and presence in discomfort. Regular cold exposure builds willpower, emotional regulation, and stress tolerance, helping you better manage challenges both physically and psychologically.

This morning I took a Qi Gong class for the first time with a friend and it was incredible! Margaret is a wonderful teacher who gently guides you through the practice. We left feeling so much better than when we came in. I’ve been coming to the clinic for their floating and sauna options for a few years and every visit is fantastic. I’m always amazed at how clean the clinic is! If you’ve never been I highly recommend it! You can’t go wrong with whatever service you choose.
