Sleep structure parameters regardless of air temperature in the control and the RF-EMF exposed groups.

Mean ± SEM values for active wakefulness (active W), quiet wakefulness (quiet W), total sleep time (TST), slow wave sleep (SWS) and paradoxical sleep (PS) for the light and dark periods and during 24 h periods. Amounts are in fact expressed as a percentage of the analysis time, which due to animal caring, is less than 24 h. Statistically significant differences between light and dark periods are represented as follows: (†) p<0.05, (††) p<0.01. Differences between the control and exposed groups are indicated as follows: (*): p<0.05.
