Cold exposure has gone from a niche wellbeing experiment to something people are genuinely using to support long-term health. And unlike a lot of trends, cryotherapy actually holds up when you look at the research. Just a few minutes in the cold can spark a whole series of protective shifts in your body… supporting metabolism, easing inflammation and helping you recover better. It’s these small, powerful adaptations that leave you feeling clearer, stronger and more resilient over time.
This isn’t about suffering for the sake of suffering. It’s about using controlled cold as a reset. As Maria Ensabella, founder of LondonCryo, explains, “Whole-body cryotherapy awakens the embedded mechanisms of self-healing and self-regeneration.” Even a single session sets off biochemical changes linked to improved ageing, better hormone regulation and higher energy levels. It’s why athletes rely on it, longevity doctors recommend it and why so many are adding cryotherapy to their weekly routine.
If you’re curious about cryo yourself, here are the five biggest longevity benefits of cryotherapy and why it’s probably worth giving it a go.
Most of us know by now that inflammation plays a huge role in how we age; from how stiff we feel in the morning to how well our metabolism functions. Cryotherapy directly supports this. “Whole-body cryotherapy reliably lowers pro-inflammatory signals and increases anti-inflammatory responses, which is essential to slowing age-related disease processes,” says Maria.
It all starts with the cold shock. As your skin cools, sensors send a “something’s happening” message to your brain. In response, your nervous system flips into protection mode, switching on anti-inflammatory pathways and dialling down the ones that keep low-grade inflammation bubbling away. By the time you step out, your body is already moving into repair. The benefits go far beyond less soreness. Lower inflammation means better mobility, more balanced hormones, stronger metabolic health and a slowing of the everyday wear-and-tear that naturally ramps up as we age.
Movement is one of the biggest predictors of long-term health and cryotherapy helps you maintain it by lowering pain and making it easier to stay active.“By lowering inflammatory pain, people can move more,” says Maria, who notes the importance of movement when it comes to both lifespan and healthspan.
During a session, the cold temporarily slows nerve signals, which can reduce pain almost instantly. Once you step out and warm up, oxygen-rich blood floods back into muscles and joints, supporting comfort, mobility and recovery.
The result? Everyday movement feels more doable. Whether that’s your gym session, a morning walk or simply keeping active as you get older. And the more you move, the healthier your cardiovascular, metabolic and musculoskeletal systems stay over time.
Cryotherapy gives your metabolism and circulation a kind of “wake-up call.” As Maria explains, the body goes through “rapid stimulus then controlled stress and then adaptive recovery.” Essentially, your system gets challenged, responds and comes back stronger.
Here’s what’s happening behind the scenes:
- Blood rushes to your core to protect your vital organs.
- Your metabolism switches on to generate heat.
- Once you step out, warm, oxygen-rich blood floods back into your muscles and tissues.
Think of it like interval training for your blood vessels. That quick squeeze-release cycle helps keep them flexible and responsive. Over time, this can mean better circulation, more stable energy, a metabolism that adapts and responds more effectively and support for long-term heart, brain and overall health.
Cold exposure doesn’t just change how your body feels… it shifts your mind too. “Adrenaline increases alertness and focus, and afterwards endorphins and serotonin are released, which often produces a noticeable lift in your mood,” says Maria.
This is why people often leave a session feeling clear, energised and unexpectedly calm. Cryotherapy triggers a short, controlled stress response followed by a deep parasympathetic rebound… the state your body uses for rest, repair and sleep. Because chronic stress and poor sleep speed up ageing more than almost anything else, regularly resetting your nervous system can have powerful long-term benefits for emotional balance, recovery and overall resilience.
Cryotherapy doesn’t fight against your biology; it works with it. Maria describes the effect as awakening “the embedded mechanisms of self-healing and self-regeneration.”
The cold creates just enough challenge to activate the pathways responsible for repair, balance and recovery. With consistency, these responses strengthen, meaning your body becomes more resilient over time. Maria has seen this repeatedly in long-term users with reduced chronic pain, better mobility, improved sleep, more stable mood and energy and less reliance on pain medication “People regain their ability to live normally and that directly supports healthspan, not just lifespan,” she says. The real benefit isn’t just the three minutes in the chamber though… it’s how your body performs after. Think a clearer head, a calmer nervous system, better recovery and a body that ages more slowly and more comfortably.
What is cryotherapy and what happens during a session?
A typical whole-body cryotherapy session lasts just 2-3 minutes but a lot happens in that time. As Maria explains, the process follows a pretty predictable sequence:
- Skin receptors detect the rapid drop in temperature. This sends an immediate alert to the brain.
- The nervous system activates a short, controlled ‘fight-or-flight’ response. “The rapid drop in skin temperature signals the brain that survival is threatened,” says Maria.
- Blood flow shifts to the core. This protects vital organs and keeps your body temperature stable.
- Your metabolism ramps up as your body generates internal heat.
- Pain signals temporarily slow which is a big reason why relief happens so quickly.
- Once you step out, the recovery phase begins. Warm, oxygen-rich blood rushes back into the tissues which helps support repair.
- Mood-elevating chemicals like endorphins, serotonin, and norepinephrine are released which often translates into feeling more energised, calm and clear.
What makes cryotherapy unique is that this entire response happens without lowering your core temperature, meaning you get the systemic benefits without the physical strain or prolonged discomfort of an ice bath. Sign. Us. Up.
So, how often should you do cryotherapy?
There’s no one-size-fits-all approach. How often you should do cryotherapy really depends on what you’re trying to support. But after working with thousands of clients, Maria has seen some clear patterns. Her go-to guidance looks like this:
- For inflammation and longevity: 3-5 sessions a week for the first 2-4 weeks, then ease into a steady rhythm of 1-2 sessions weekly.
- For chronic pain: Daily or near-daily sessions to begin with, then regular top-ups once things start to improve.
- For mood, stress and sleep: 2-3 sessions a week works well for most people or short daily bursts if your symptoms are really showing up and need extra support.
- For athletic recovery: Pop in after heavy training days or competitions to speed up recovery without slowing performance.
Maria’s best advice? “Benefits are cumulative and consistency matters more than intensity.” Cryotherapy works like training… the more regularly you do it, the stronger and more adaptive you become.
Your most asked cryotherapy questions, answered
Yes, for most people. Those with uncontrolled hypertension, cardiovascular disease, Raynaud’s or pregnancy should avoid it though and we’d always suggest consulting a medical professional if you’re unsure.
Typically around 2-3 minutes which is long enough to activate systemic responses without lowering your core body temperature.
Many feel clearer and more energised immediately. Pain relief and improved sleep often happens after a few consistent sessions though.
Cryotherapy triggers a systemic thermoregulatory response in just a few minutes whereas ice baths cool tissue more slowly and locally, meaning you need at least 10-20 minutes for this to get to work.
