Sleep State Expressed as a Percentage of Total Sleep Time in the Different Thermal Conditions
| Thermoneutrality | Warm exposure | Cool exposure | |
|---|---|---|---|
| Total sleep time, min | 112 ± 20 | 107 ± 39 | 98 ± 32 |
| Sleep state | |||
| Active | 65.4 ± 8.5 | 66.9 ± 7.1 | 72.7 ± 12.2a,b |
| Quiet | 25.3 ± 6.8 | 23.5 ± 7.5 | 19.9 ± 10.0c |
| Intermediate | 9.3 ± 4.9 | 9.6 ± 5.6 | 7.4 ± 5.7 |
Thermal condition × sleep state interaction: F2,84 = 2.94, P = 0.025.
a
Cool exposure vs thermoneutrality in active sleep: P = 0.013
b
Cool vs warm exposure in active sleep: P = 0.049
c
Cool exposure vs thermoneutrality in quiet sleep: P = 0.032
