Feel more secure with a proper intake undergoing whole-body cryo, part 2: The intake session

We believe that every new client should start with a proper intake consult. In our previous blog, we discussed the first part of the intake consult, the intake interview. Remember, the intake interview enables you to create a foundation for the relationship with your new client, provides the opportunity to sell the concept, helps you to understand the clients’objective, and supports you to determines whether it will be safe for your client to be exposed. In this blog, we will capture the second part of the intake consult, the intake interview.

Potential clients who are curious about whole-body cryo should undergo an intake session to improve SAFETY, EFFICACY, and COMPLIANCE. This intake session is a session that is the same for every client and has a mild intensity; we recommend 2 minutes at -90°C/-135°F.

This standard, mild exposure session has multiple advantages:

  1. Safety: It helps the practitioner to assess if a client is cold susceptible
  2. Efficacy: It provides the practitioner information on how the client responds to whole- body cryo
  3. Compliance: It helps a client to get acquainted with whole-body cryo.

Whole-body cryo exposure will elicit bodily reactions. The heart rate goes up; breathing rate increases, etc. The environment is a treat for survival, so your body responds to survive. Everybody will respond similarly, however, because we are so different, the responses might be more or less intense. Also, subjectively, whole-body cryo is perceived differently by each individual.

In a healthy volunteer study performed by the ProCcare team at sports medical centerFysiomed Amsterdam, 97 volunteers were exposed to the same dosage of 2 minutes at -90°C/-135°F. One of the outcomes that were assessed was thermal comfort, according to Zhang and colleagues (2003). This mild exposure session already illustrated a wide difference in how people perceive whole-body cryo; 7% perceived it as comfortably normal, 76% as comfortably cold, and 17% perceived this mild session as uncomfortably cold (see figure 1).

Advantage 1: Safety

Some people are more susceptible to severe cold than others, which results in a more intense physiological response or even an allergic reaction on the skin. Research tells us that factors as age, skin type, gender, and fitness affect how people respond to such extreme temperatures. For instance, a woman, at a higher age, with darker skin and low fitness, appears to be at the highest risk. Cholewka and colleagues (2012, see figure 2) illustrated that people’s skin temperature responds differently to whole-body cryo and attributes this effect to different body adiposity.

Figure2: Skin temperature response of two patients undergoing the same dosage (30 sec at -60°C/-76°F and 120 sec at -100°C/-148°F) of whole-body cryo.

While the drop in general skin temperature of patient 2 stays rather high, as on average a drop of 10°C/18°F would be expected; patient 1 shows a general skin temperature of about 10°C/18°F at the end of the treatment. This temperature is pretty close to the reported barrier (skin temperature of 5-8°C/41-46°F) in which one can develop skin problems, like cold burns. The graph only shows the general skin temperature; local regions (for instance, the shins or triceps)might, therefore, already be at risk.

Patient1, in this example, seems quite susceptible to cold. Prescribing an intake session would have put the specialist in the position to act upon this information, making sure this patient would have been treated more safely.

Advantage 2: Efficacy

People come to your facility with a certain objective. They want to optimize their recovery, want to feel revitalized, or perceive less pain. To reach their goal, they look for the most optimal approach. They expect whole-body cryo can help them, not knowing how their body will respond. In case their body is more susceptible, the extent of their response might be more significant. Resulting in overstimulation and not reaching the wanted effect. For instance, when using whole-body cryo to enhance sleep when being more susceptible, it might result in excessive vasoconstriction, resulting in cold feet, which makes it even worse to fall asleep.

Advantage 3: Compliance

When your new client has never experienced whole-body cryo before, the first time(s)this client might come in a bit nervous. This client does not know what to expect.  Making sure that the client trusts you and acknowledges you as a specialist is essential to start with a session and becoming a regular client. An intake session is a perfect tool for your client to get used to the feeling, and for you to illustrate your expertise.

CustoRec whole-body cryo software solution

New clients should always start with an intake consult, consisting of an intake interview and an intake session. Therefore, the intake consult is one of the main assets that is integrated into our CustoRec whole-body cryo software solution. The input of the intake session determines the so-called “susceptibility factor,” while the intake interview results in providing the optimal treatment cycle in terms of duration, temperature, and the number of exposures. The susceptibility factor works as a corrective factor by taking into account the perceived thermal comfort, age, and fitness. This susceptibility factor increases the safety of your client, making sure the dosage will not be too intense. When, for instance, the standard protocol is set at 3 minutes at -120°C/-184°F, the sensitivity factor recalculates this protocol to 2minutes and 45 seconds at -120°C/-184°Fwhen someone appeared to be more susceptible — thereby improving safety, efficacy, and compliance!
