Brief summary
The objective of this study is to assess the effectiveness of naps under different environmental conditions and a rest without nap, on driving, alertness and psychomotor performance. This study also aims to record during nap time, sleep, body temperature and heart rate.
Detailed description
Nap time is one of the most effective means of combating decreased alertness throughout the day and maintaining cognitive and psychomotor performance. As such, it is recommended for long-haul drivers driving their vehicle. However, these drivers have no alternative but to sleep in their seats. These conditions are not optimal for producing quality sleep. The motorcyclist, for his part, has no chance of sleeping without finding a place to feel safe to give himself up to sleep. On these bases, SOMBOX has developed a mini-hotel allowing drivers to find an optimized place to take a nap. Investigators propose an experimental study to evaluate the effectiveness, on simulator driving performance and on the results obtained during cognitive and motor testing, of a nap taken under three different conditions. The effect of the nap will be assessed by comparison to a rest awake. This study should include healthy volunteer participants.
