What is Cryotherapy

Looking like something fresh out of an ’80s sci-fi flick, cryotherapy is the latest craze to hit the mainstream. Used by athletes and celebrities looking for their next holistic fix, the high tech treatment is said to be more than just a gimmick. According to its regular users, freezing yourself for several minutes can aid muscle regeneration, boost your immune system and rejuvenate your skin.

But what exactly is it? And does it really work? Well, I tried it out at Saisei holistic cryotherapy studio in North London to find out.

What is Cryotherapy?

Before going into how it feels to step inside a coffin-sized cryo chamber, let’s have a look at what exactly is cryotherapy.

Literally meaning “cold therapy”, cryotherapy is a technique where the body is exposed to extremely cold temperatures for several minutes. It can be delivered to just one area, or you can opt for whole-body cryotherapy like I did. The latter includes immersing the body in extremely cold air for several minutes, in the belief that you’ll receive a number of health benefits. You stand in an enclosed chamber that surrounds your entire body but has an opening for your head at the top, and the cool air, or liquid nitrogen vapor, circulates around your body in the chamber for 2 to 3 minutes.

How it works

The cold air is delivered to the chamber via a cylinder of liquid nitrogen vapor, with a temperature that ranges between -120˚C to -160˚C.

When I visited Saisei, I met with the studio’s owner, wellness and fitness strategist Nyambe Ikasaya. He told me that the cold air of cryotherapy is void of moisture, and so it’s much more tolerable. This means it doesn’t penetrate deep into other tissues like the muscle and bone, and thus works on the surface area of the skin. This is why you’re able to warm up back up fairly quickly after the treatment.

“On the surface of our skin we have skin receptors which pick up changes in temperature,” Ikasaya said. “We have heat and cold receptors. 50,000 heat receptors and 280,0000 cold receptors. When exposed to temperatures of -120 degrees and below, 280,000 cold receptors pick up this change in temperature and what the body does to adapt to this change is magic!”

He continued to explain that the first step the body takes to protect its core temperature is to redirect blood from superficial vessels and capillaries in the skin towards deeper structures. This causes blood to flow from the periphery (legs and arms) towards the central core.

“This blood is enriched with anti-inflammatory proteins, red blood cells, white blood cells, enzymes, endorphins along with dopamine and serotonin,” he added. “The rebound that happens after the treatment of two and a half minutes to three minutes is re-circulation of the enriched blood to the rest of the cells in the body.”

This, he said, leads to:

• Rejuvenation

• Pain reduction

• Reduction in inflammation including inflammatory conditions like arthritis

• Improved detoxification

• Repair cellular damage which aids recovery after exercise

• Increased circulation which leads to increased metabolism

My experience

What I liked the most about this treatment is that it’s very holistic, and it’s just about getting the body to do what it already does naturally in an enhanced way. After leaving the chamber, you’ll instantly feel more alert and – strangely – happier. Apparently, this is apparently normal, as cryotherapy is also known to raise endorphin levels temporarily.

I had quite a sore knee after training in the lead up to my triathlon and definitely felt like the soreness had been reduced immediately after the cryo treatment. Obviously, it’s very cold, but it’s not uncomfortable. It was, overall, a pleasant experience and I would do it again.
