Ruz then went to the competition area. A doctor attached a pulse meter to her chest so the judge, sitting in a lifeguard-type chair overlooking the five sofas, could tell whether she's really asleep.
In this competition, the siesta is limited to 20 minutes, a duration which the organizers and some doctors say is optimal; a quick nap after lunch to get refreshed, without entering a deep sleep cycle.[...]
The intricate rules award points to contestants depending on how long they sleep during the 20-minute competition time, any unusual positions they sleep in, eye-catching pajamas they might be wearing, and yes, a lot of extra points for snoring.

The fact is napping during summer in Spain specially in the south it's a need because it's too hot to work so you only can sleep.
After at night you can't go to sleep because you had a nap in the afternoon so you go out at the terrace in a bar till late.
Next day in the afternoon it's too hot to work , and you feel sleepy , so we start all over again.
I some towns they had special laws for the napping time:
No noisy teenage motorbikes allowed in town
No bells from the church
