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).
Interventions
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).

Inclusion criteria
Medically stable (based on physical examination, medical history and vital signs at screening) adults with a diagnosis of mild cognitive impairment (MCI; F06.7 according to research criteria of International Classification of Diseases, ICD-10) (World Health Organization, 2004) with additional inclusion criteria based on the Montreal Cognitive Assessment (MoCA) test (Magierska, Magierski, Fendler, Kloszewska, & Sobów, 2012; Nasreddine et al., 2005; Talarowska, Florkowski, Zboralski, & Galecki, 2011) (scores between 20 and 26).
Exclusion criteria
The exclusion criteria included 1) a lack of or more advanced cognitive decline (20<MoCA>26), 2) depression, 3) previous exposure to WBC 4) being over 85 years old and 5) all standard contraindications to use WBC (e.g. alcohol and drug abuse, inability to understand questions and written information, psychosis, suicidal thoughts, standard contraindications to use WBC (e.g. acute respiratory diseases, acute cardiovascular disease like coronary disease, circulatory insufficiency, unstable hypertension, cold intolerance, claustrophobia, cryoglobulinemia, cancer, deep vein diseases, hypothyroidism, neuropathies, purulent skin changes, Reynaud disease).
