Study: NCT05181345

Intervention type: OTHER
Intervention: Heat exposure
Description: The subjects will be exposed twice (2 different visits) to heat (45°C; 60-70% humidity rate) for 3 hours in a climate chamber.~The subjects will be equipped with various external sensors allowing the continuous recording of core temperature, mean skin temperature (9 skin measurement points), heart rate, cerebral electrical activity, cerebral oxygenation, skin vascular conductance (blood flow by laser-doppler), blood pressure and skin conductance.~Neurophysiological and cognitive exploration (NPCE) includes the Stroop test, the Psychomotor Vigilance Task (PVT) and the odd-ball test.

Intervention: Normal sleep
Description: The night before one of the two heat exposures (first visit for the Normal sleep first group and second visit for the Reduced sleep first group), the participants will have a normal night at home. The duration and quality of sleep will be measured using a connected headband (Dreem®) allowing for polysomnography.

Intervention type: OTHER
Intervention: Sleep restriction
Description: The night before one of the two heat exposures (first visit for the Reduced sleep first group and second visit for the Normal sleep first group), the participants' sleep will be restricted. The sleep restriction will correspond to a reduced sleep period with a bedtime of 3 hours (04:00 - 07:00). This night of sleep restriction will be carried out in a sleep apartment (at the lab). The duration and quality of sleep will be measured using a connected headband (Dreem®) allowing for polysomnography.
