Today is part four of our sleep series. We will explain how a power naps works. If you have any questions, write to us, and we will answer them in our next Podcast!
How do I do a Power Nap?
- Put away your mobile phone
- Switch off disturbing noises through relaxed music
- darken the room
- Nap should be between 15 and 30 minutes long (2)
- Coffee-Nap: Drink a coffee before you want to do a Power Nap
- Avoidance of deep sleep phases (N3 and REM) (7)
How does a Power Nap work?
- Reduction of sleep deprivation (6)
- Improvement of acute performance in athletes who sleep <7h at night (1,2, 6)
- Increase of attention, alertness and concentration (4)
- Stress relief
- Reduced susceptibility to infections (2)
- A Power Nap 3 times a week reduces the risk of a heart attack by 37% (5)
The scientific evidence of the effectiveness of Power Naps is currently insufficiently researched. Studies often speak of a positive or no effect at all.
- Study by Waterhouse et al. 2007 shows an improvement of the sprint performance after a 30 min Nap (8)
