Description of intervention(s) / exposure
The Whole-Body Cryotherapy (WBC).

A cryotherapy chamber (CR 2002, Wroclaw type, provided by Creator Sp. z o. o.), cooled by liquid nitrogen consists of two rooms: the vestibule/antechamber (temperature: -60 C-degrees) and the proper chamber (temperature – days: 1st day: -110 C-degrees, 2nd: - 115 C-degrees, 3rd: -120 C-degrees, 4th: -130 C-degrees, 5th and 6th: -135 C-degrees, 7th: -130 C-degrees, 8th: -125 C-degrees, 9th: -120 C-degrees, 10th: -115 C-degrees). There is no direct contact with the liquid nitrogen in this type of device.
The usual WBC session lasts for 2 minutes in the main chamber with 30 seconds extra for adaptation in the vestibule before and after the proper session. Each procedure is under control by the personnel - the interevntion was administered by physiotherapist.
A group of 5–6 people usually uses the device at the same time. Participants are required to wear shorts and t-shirt, gloves, headband or beanie, a nose and mouth mask, high-knee socks and wooden shoes. This outfit should be woollen or cotton to reduce the risk of injuries caused by cold. Before every WBC session participants had the blood pressure measured.
Participants undertake 10 whole-body cryotherapy sessions for two weeks (Monday–Friday without weekend).

Summary
Brief summary
Mild Cognitive Impairments (MCI) and dementia are still incurable. The Whole-Body Cryotherapy (WBC) - short, cyclic exposure to extremely low temperatures - has proven anti-inflammatory and anti-oxidative effects. It can also induce hormonal, lipid and neural changes. This research project aimed to determine the efficacy of cognitive functioning and the biological mechanisms of whole-body cryotherapy in people with mild cognitive impairment (MCI).
