How can a human being stand the temperatures below -120°F?

In a long term, it could not, as the cold would damage the tissue. This is the reason why cryosauna treatment needs to be so short. Length of the treatment has been established to get the skin temperature down to not less than 34 F. This way, frostbite does not happen, while the body thinks it is freezing and mobilizes all its resources to stay alive. 3 min treatment in cryosauna is much more effective and tolerable than taking a cold shower or sitting in an ice bath.

Does cryosauna treatment hurt?

No, it does not. Even though the temperatures used are extremely low, the air that circulates around the body inside cryosauna is completely dry. It makes the treatment surprisingly comfortable, much better than "wet cold" created by cold shower or a plunge in ice cold water. There is no actual freezing involved, no tissue gets damaged, and the chill that lasts for less than 3 minutes causes slight shivering, at most. Most people never do, while some are more cold-sensitive than the others. It is important to understand that cryosauna user will never be left alone, and the treatment could be stopped any moment if the cold feels too much. Many people start with a shorter first treatment to get used to it, but, in many cases, whole body cryotherapy is used even by people who "hate cold".

What do I wear?

We provide every client with a robe, socks, slippers and gloves that are used to protect your extremities during the treatment. Men are required to wear boxers or underwear. All clients must remove all jewelry and exterior metal/body piercings. Additionally, it is recommended that you pat yourself dry with a towel and do not apply oils, lotions, or cologne immediately prior to treatment.

Why is it necessary to take a cryosauna treatment undressed?

Since cryotherapy relies on the body's reaction to cold, it is essential that skin surface with its cold sensors is maximally exposed to the surrounding extreme temperatures. Every piece of cloth that is left on reduces effectiveness of the treatment. There are just a few exceptions: feet and, particularly, toes; fingertips; and genitalia in men. These areas are simply too sensitive to cold and could not stand it for the required 3 minutes. For this reason, men are required to wear briefs or other cotton protection, and everybody must have thick natural material socks and gloves to cover toes and fingertips.

Can one catch a cold from the effects of cryosauna?

No. The cryo session will enhance the blood flow and cause a short-term increase of the systolic blood pressure. Body temperature may go slightly up for a short period of time, but it will return to normal soon after the treatment is over. Actually, the stimulation of the immune system can help decrease the severity and frequency of future colds and susceptibility to the flu.

Why are socks and gloves required?

Toes and fingertips have an extremely high concentration of nerve endings that make them more cold-sensitive than other parts of the body. In addition, while in cryosauna, the body pulls the blood away from the extremities and into the core, so the extremities must have extra protection. Both socks and gloves shall be completely dry, thick and natural (preferably, cotton or wool).

Is there a need for a shower before and/or after the procedure?

No. This procedure requires the skin and everything on it to be completely dry (no water, sweat, body lotions, creams, or oils that, if used, should be wiped off by a dry towel before stepping into the cryosauna). Perspiration or any other secretion is not involved in the process. Damp socks or underwear are not permitted, either, as any residual moisture will freeze and lead to frostbites.

Isn't nitrogen dangerous to human beings?

No, it is not. Nitrogen is a non-toxic, natural gas that we constantly breathe - only 16% of the air is oxygen, while 78% is nitrogen! If one inhales too much nitrogen, it can cause slight dizziness or even passing out, but nitrogen-cooled cryosaunas prevent it from happening, as client's head is outside during the treatment, while more concentrated cold nitrogen vapor that is heavier than air stays inside the cryosauna cabin. To create the required cold, treatment providers receive nitrogen in its liquid form and under low pressure of 22 psi. It is neither flammable nor explosive. The specially designed cylinders prevent the extremely cold liquid from spilling, and the treatment equipment is built to make contact between client's skin and liquid nitrogen impossible. Therefore, all risks are eliminated.

What to expect from the cryosauna treatment?

Cryosauna uses nitrogen to lower the user's skin surface temperature to 34° - 40° F for up to 3 min. By getting in touch with the extremely cold environment, cold receptors located on the skin send powerful signals to the brain to turn on the protection mode. Reduction of the skin temperature serves as a stimulant to all regulatory functions of the body. It also engages the areas that may not be performing to their fullest potential. So, while the exposed to the cold human body feels the cryo chill and, maybe, slight tingling of the skin, it does its best to make sure all vital functions are sustained - blood vessel constriction on the surface drives blood to the core, systolic blood pressure increases, and all organs receive more oxygen and nutrients. As soon as the treatment is over, blood rushes back to the peripheral tissues and delivers more oxygen and nutrients there. The body feels warm and energized. Many have reported immediate reduction of aches and pains, and the released endorphins improve mood. The immediate effects can last for several hours, while the intangible improvements accumulate gradually. To achieve sustainable results, just one cryosauna treatment will never be enough.

Who should NOT use whole body cryotherapy?

Individuals with the following conditions are strongly advised not to use whole body cryotheraphy, as it may cause health-related issues:

  • Severe hypertension (BP>180/100)
  • Cardiovascular disorders and recent cardiovascular surgeries
  • Cerebral palsy
  • Uncontrolled seizures
  • Difficulty breathing
  • Cancers or tumors
  • Acute infections
  • Bleeding disorders
  • Cold allergies
  • Fever
Think of it this way: whole body cryotherapy enhances blood circulation and briefly increases systolic blood pressure. Most people benefit from it and are not in any kind of risk, but, in some cases, blood circulation improvement may be unwanted. For example, it may help spread a local infection. It is recommended not to use cryotherapy during pregnancy due to potential risks that have never been evaluated.

How often should cryosauna be used?

It is recommended to commit to at least 10 cryotreatments in the first 30 days for optimal results. Some people will need more, while some conditions will be better helped by maximum frequency (5-7 treatments per week). People suffering from pain may find more relief in more concentrated treatments for a longer period, until a remarkable improvement is achieved. In a post-surgery or post-injury stage, even a few consecutive treatments could substantially reduce the inflammation and swelling. A cryo technician will be happy to help customize a treatment plan, depending on the desired results.

Are there age restrictions?

Although the cryosauna produces completely natural results, the cabins are only designed for an adult-sized bodies. If height is sufficient, age does not matter, as long as the client is able to move enough to enter the cryosauna cabin and to stand unsupported for up to 3 minutes.

Can whole body cryotherapy be used by claustrophobic people?

Yes, it can. If you are afraid of close spaces. while in our cryosauna the client's head is above the edge of the cabin during the treatment, and the operator is always there, observing, communicating and ready to help, if necessary. Also, the door is never locked, and the treatment can be stopped any moment.

Is it ok to be active or exercise right before or after a cryosauna treatment?

Yes! It is completely safe, and beneficial, either way. A cryosauna treatment before a physical activity may lead to higher pain tolerance, more energy, greater flexibility, and better endurance. Cryo treatment after a workout will help to reduce inflammation and muscle soreness, lead to fuller relaxation and deeper sleep at night. Even though it is not recommended to do more than one treatment per day, as it could be too much stimulation and stress for the body, there can be exceptions. For example, marathon runners often do two treatments, before and after, on the day of the race.


How long will my tan last?

Most spray tans last roughly 7 to 10 days, though certain factors can extend or shorten that period.

Am I protected from UV sun rays?

No. Spray tan solution doesn't have any kind of sunblock in it. If you are going out, put on sunblock.

Is there anything I should do to prepare for my spray tan appointment?

Preparation and maintenance of your sunless tan is the KEY to sunless success.

Follow these important steps to ensure maximum sunless results:

  1. GENTLY exfoliate your skin prior to your sunless spray session. A gentle, sulfate-free skin polish, such as Norvell Renewing Sunless Exfoliator, can be used prior to your sunless session.
  2. Any waxing or shaving should be performed 24 hours in advance of applying sunless products.
  3. Remove any 'barriers' that may prevent the sunless product from absorbing into the skin evenly. These include, but are not limited to: make-up, deodorant, perfume, oils, moisturizers, residue from hair conditioners.
  4. Optimize your skin surface pH levels prior to application. Do not use bar soaps prior to your sunless tan, and ask your technician to apply Norvell Pre-Sunless xLaTan Ph Balancing Spray.

Whta is DHA (Dihydroxyacetone)

DHA is an acronym for Dihydroxyacetone.

DHA is the active ingredient found in all sunless tanning products. It is a simple carbohydrate that is primarily used as an ingredient in sunless tanning products. It is often derived from plant sources such as sugar beets and sugar cane, and by the fermentation of glycerin. DHA does not make your skin cells darker in pigmentation, but rather reacts with the proteins and amino acids found in the top layer of your skin to create a darkening effect or 'sunless tan'.

Will I turn orange?

When used as recommended, Norvell's professional products are formulated to give a natural, just off the beach™ color, starting with our perfectly blended instant cosmetic bronzers that allow you to gently transition into your DHA tan over 24 hours after application.

High pH levels in the skin can sometimes give individuals an undesirable, 'fake' non-natural looking sunless color. Sunless application on skin that is out of balance due to high pH levels sometimes results in what many people refer to as an 'orange' coloring.

To prevent this from happening, there are a few things you can do:

  • Do not use bar soaps before your sunless session. A properly pH balanced skin cleanser will not elevate pH levels on the skin, and result in more 'golden brown' sunless tanning results.
  • We recommend spraying the body with Pre Sunless xLaTan pH Balancing Spray prior to any sunless application. This product is formulated to lower the pH levels of the skin giving a more golden brown color, and maximizing your sunless results.

What should I wear to my appointment?

Wear loose clothing and shoes in dark colors. Your bra should also be the loose variety (no sports bras), and you may even want to leave it off after your treatment. During your session disposable thongs are available or feel free to wear a bathing suit or undergarments of your choice. Just know tan lines will apear where clothes are. Men are required to wear underwear, shorts or bathing suits.

When should I shower afterwards?

Wait at least 5 -8 hours before showering. Ideally you should wait 24 hours before showering. It's crucial to avoid any swimming or sweating, not to apply any products or moisturize, and not to exfoliate before this first shower. All of these things can make your spray tan uneven or streaky.

Is there anything I shouldn't use on my skin after my treatment?

Avoid scented lotions, perfumes, astringents, and cleaning solutions with acid or peroxide. Anything harsh or chemical will wear away your tan more quickly.

Is there anything I should use on my skin after my first shower?

Moisturize, moisturize, moisturize! Natural, fragrance-free lotions are best. This will ensure that your skin remains healthy and hydrated, and that your spray tan lasts longer.

How can I prevent patchy or uneven wear-off?

Many individual factors can contribute to patch or uneven wear-off, as each person's skin is different. It is best to follow our Preparation and Maintenance Guide for maximum sunless results.

  • Be sure to gently polish and exfoliate the skin before each sunless session using
  • Keep skin hydrated on the inside and out. Moisturizer will extend the look of your tan.
  • It is also recommended that individuals not tan more than 3 times in a 2 week period, to avoid build-up of tanning solution that will contribute to uneven wear-off.

How long after tanning should I wait to enjoy pools/spa/ocean?

We recommend avoiding these situations for the first 48 hours following your spray tan. Chlorinated pools & spas can increase the rate in which the skin exfoliates causing the tan to wear and fade rapidly.

What else can I do to make sure my tan lasts as long as possible?

While your spray tan is new, you'll want to avoid chlorinated water, as this can make the color fade faster. In addition, cut the amount of shaving you do down to a minimum, as this works as an exfoliant and will also make your tan fade. Once your tan has started fading naturally, you can resume most of your normal skincare regimen.
