QUICK ANSWER Float tanks, ice baths and infrared saunas all support recovery but work through completely different mechanisms. Float tanks reduce stress, decompress joints and improve sleep. Ice baths manage acute post-training inflammation. Infrared saunas penetrate muscle tissue with heat to reduce soreness and support circulation. The best recovery tool depends on what your body needs — and they work even better when combined. |
Introduction
Cold plunges are everywhere right now. Infrared saunas have gone from niche to mainstream. And float tanks have been quietly delivering serious results for decades while the rest of the wellness world catches up. If you're trying to figure out which of these is actually worth your time and money — or whether they work better together — this is the honest breakdown.
Why recovery tools matter more than most people think.
Training, stress, poor sleep and daily physical load all break the body down. The question isn't whether you need recovery — it's which tool addresses what your body is actually asking for.
The three most talked-about recovery modalities right now — float therapy, ice baths and infrared sauna — each work through completely different mechanisms. They're not interchangeable. The one that's right for you depends on what you're trying to fix.
Float tank — what it does and who it's for.
A float tank fills a private pod with around 500kg of dissolved Epsom salt (magnesium sulphate) in water held at skin temperature — approximately 35.5°C. The salt creates buoyancy so complete that the body floats effortlessly on the surface. With the option to remove light and sound entirely, the nervous system receives something it rarely gets: no external input whatsoever.
What actually happens:
• Cortisol — the primary stress hormone — drops measurably within the first 20 minutes
• Magnesium is absorbed transdermally through the skin, supporting muscle function and nervous system regulation
• Every joint in the body decompresses simultaneously as gravity is removed
• The brain enters theta brainwave states — the same as deep meditation — naturally and without effort
• Deep muscular tension releases in ways that aren't possible in any other position
Best for:
• Chronic stress, anxiety and mental fatigue
• Back pain, joint pain and accumulated physical tension
• Sleep improvement — most guests sleep noticeably better the same night
• Athletic recovery — particularly in the 24–48 hours following hard training or competition
• Anyone who hasn't had a genuinely quiet hour in weeks
Not the tool for:
• Acute inflammation immediately post-injury (ice is better here)
• Someone who needs to feel energised and activated, not relaxed
Session length: 60 or 90 minutes

Ice bath / cold plunge — what it does and who it's for.
Cold water immersion — whether a purpose-built cold plunge, an ice bath or open water swimming — involves submerging the body in water typically between 10–15°C for anywhere from 2 to 15 minutes. Interest in cold plunge therapy has surged dramatically in recent years, with Yelp reporting a 521% increase in searches since 2022.
What actually happens:
• Blood vessels constrict sharply (vasoconstriction), reducing blood flow to muscles and blunting acute inflammatory response
• The body's stress response activates — cortisol and adrenaline spike briefly
• After exiting, blood rushes back to the periphery (vasodilation), clearing metabolic waste
• Cold shock proteins are triggered, which may support cellular repair over time
• Dopamine levels rise post-immersion, producing a mood elevation effect
Best for:
• Acute post-training inflammation — particularly in the first few hours after intense exercise
• Mental resilience and mood — the dopamine spike is real and well-documented
• Waking up and activating the nervous system — cold is stimulating, not sedating
• People who enjoy the challenge and the post-plunge feeling
Not the tool for:
• Chronic pain, stress or sleep issues — cold activates the nervous system rather than calming it
• People managing anxiety — the stress response triggered by cold can exacerbate anxiety symptoms
• Long-term muscle growth — some research suggests cold immediately post-strength training may blunt hypertrophy adaptations
NOTE: Tally Floathouse doesn't offer cold plunge — but if you're combining cold with float or sauna, the typical protocol is cold first, heat or float after. |
Infrared sauna — what it does and who it's for.
Unlike traditional steam saunas that heat the air to 80–100°C, infrared saunas use light wavelengths to warm the body directly at a far more comfortable 45–60°C. The lower ambient temperature means longer, more tolerable sessions — and deeper penetration into muscle tissue.
What actually happens:
• Infrared heat penetrates up to 4cm into muscle tissue, increasing circulation and accelerating the clearance of inflammatory markers
• Core body temperature rises, triggering a cardiovascular response similar to moderate exercise
• Deep sweating supports the body's natural detoxification pathways
• Cortisol decreases and the parasympathetic nervous system activates — producing relaxation rather than stimulation
• Magnesium and mineral absorption through the skin is supported
Best for:
• Muscle soreness and recovery — particularly for chronic tightness or post-training soreness
• Skin health and circulation — increased blood flow to the skin's surface delivers nutrients and supports collagen production
• Cardiovascular support — regular use is associated with improved circulation and blood pressure
• Stress and cortisol reduction — the heat response is calming, unlike cold
• Warming up the body before a float — the combination is particularly effective
Not the tool for:
• Acute post-injury swelling — heat increases blood flow and can worsen acute inflammation
• Anyone with conditions where elevated core temperature is a concern (pregnancy, certain cardiovascular conditions)
Session length: 45 or 90 minutes

Can you combine them? And should you?
Yes — and the combination is where things get genuinely interesting.
Sauna then float
This is the most popular combination at Tally and for good reason. The infrared heat loosens tight muscles and reduces cortisol before you enter the float pod, so the transition into deep relaxation happens faster and goes further. Many guests who try this describe their float as more immersive and more restorative than a standalone session.
Cold then heat (contrast therapy)
The protocol of cold plunge followed by sauna or float taps into the body's alternating vasoconstriction and vasodilation response to drive circulation, clear inflammation and produce a profound mood and energy effect. If you have access to a cold plunge elsewhere, doing it before your infrared sauna or float at Tally is a smart protocol.
Float and cold on the same day
Less common and generally not recommended back to back — the float produces a deeply sedated, parasympathetic state that cold immediately disrupts. If using both, float in the morning or cold plunge first, float after.
Which one should you start with?
Start with float therapy if:
• You're managing stress, anxiety, burnout or chronic mental fatigue
• You have back pain, joint pain or persistent muscular tension
• Your sleep is consistently poor
• You've never tried any of these and want the most complete, lowest-effort reset
Start with infrared sauna if:
• You want something more social or shared
• You're primarily focused on muscle recovery and skin health
• You want to try both — sauna first is the natural entry point to the float experience
• Budget is a consideration — sauna sessions start from $45
Add cold plunge if:
• You already float or sauna regularly and want to amplify the contrast effect
• You're training hard and want acute post-training inflammation management
• You enjoy the mental challenge and the post-plunge dopamine hit
The honest answer.
Float therapy, ice baths and infrared sauna all work. They work differently, for different things, at different moments in a recovery or wellness routine. The mistake most people make is treating them as competing options rather than complementary tools.
If you had to choose one to start with — and you're managing the kind of stress, tension and sleep disruption that most people in Melbourne are carrying right now — float therapy is the highest-leverage first move. It addresses the most things simultaneously, requires nothing from you, and the results are felt immediately.
If you want to go deeper, add infrared sauna. At Tally Floathouse, our 30 Minute Sauna & 60 Minute Float combo ($99) is the most popular session we offer — and it's popular for exactly this reason.

Frequently asked questions.
Is float therapy or infrared sauna better for muscle recovery?
Both are effective but work differently. Infrared sauna is better for post-training soreness and immediate muscle relief through heat penetration. Float therapy is better for full-body joint decompression, magnesium replenishment and nervous system recovery — particularly in the 24–48 hours after hard training. The combination of both in one visit is the most complete recovery option available at Tally.
Can I do a float and sauna in the same session?
Yes — and we recommend it. Our 30 Minute Infrared Sauna & 60 Minute Float combo is $99. Do the sauna first — the heat primes your body for a deeper float. Arrive 40 minutes before your booked float time for your sauna.
Is cold plunge or float therapy better for anxiety?
Float therapy is significantly better suited for anxiety. The sensory-reduced environment signals safety to the nervous system, cortisol drops measurably, and the parasympathetic response is deep and sustained. Cold plunge activates the stress response — which can be beneficial for mood but is generally counterproductive for anxiety management.
How often should I use infrared sauna vs float tank?
For most people, a combination of one float and one sauna session per week during busy or high-stress periods delivers the best results. Our Wellness Membership at $12/month gives you discounted access to both — 60 minute floats at $55 and 45 minute sauna sessions at $30.
