Background: We aimed at evaluating the feasibility and effects of intense (i.e. -90°C) whole-body cryostimulation (WBC) on somnolence and psychological well-being in an older-adult patient diagnosed with restless legs syndrome (RLS).
Methods: An interrupted time series approach was used in which the efficacy of cryostimulation was evaluated by measuring self-reported fatigue, wake time sleepiness, and well-being several times prior to, during, and after exposure to treatment (i.e. daily 3-min sessions of intense WBC).
Results: No adverse event occurred. Reported levels of sleepiness decreased immediately following the beginning of the treatment phase. In the same time, self-reported well-being significantly increased. Effects sizes were of large magnitude.
Conclusion: In summary, the present study demonstrated that daily exposure to extremely cold air in an enclosed space for 2 weeks was feasible and effective in promoting physical and psychological states in an older patient with sleep disturbances.
