• During the treatment, guests lie in the pod and use a VR headset to see, hear, smell and feel sensations of nature.

• Proposed benefits include improved attention, stress reduction and mood enhancement.

• Cleaning takes two minutes and requires replacement of disposable face inserts on the headset and all contact surfaces being wiped with disinfectant wipes. The pod is capable of withstanding hospital-grade disinfectant.

• Benefits include enhancing immunity, anti-ageing, muscle rehabilitation and stress relief.

• It’s considered a COVID-safe treatment as it’s touchless and guests can wear protective masks and gloves and are provided with shoes so they don’t come into contact with surfaces.

• What’s more, viruses do not like the extreme cold temperatures (-110˚C) of cryotherapy.

• The stainless steel floor of the chambers are capable of withstanding hospital-grade disinfectant.

• Sessions cost £80 (€89, US$101), but guests can have up to five daily and artofcryo.com estimates spas could offer 50 treatments a day in a single chamber under corona-friendly restrictions. Or it says up to 200 sessions could take place a day in its multi-room vario Vaultz model under normal circumstances.

• Studies show halotherapy can relieve symptoms of upper and lower respiratory conditions and improve the skin.

• It also has anti-microbial and anti-bacterial properties which Himalayan Source claims will help protect treatment rooms from viruses.

• Cleaning takes 15 minutes and requires massage tables to be disinfected and disposable sheets on the bed to be replaced between sessions.
