^aChange in sleep parameters, total sleep, number of episodes, maximum episode length, P(doze), and P(wake) on the recovery day (21°C) were analyzed for day (LP) and night (DP) separately. One-way ANOVA followed by Bonferroni test or Kruskal–Wallis (K-W) followed by Dunn's test was applied based on distribution of the datasets.

*p < 0.05.

**p < 0.01.
