Other forms: siestas
You can make your afternoon nap sound a little more exotic if you call it a siesta. In some countries, it's common for people to take a siesta after lunch.
In warm parts of Southern Europe and the Mediterranean, the siesta is an important part of the culture. It's especially ingrained in Spain—and in Italy, where it's called a riposo. The Spanish word siesta, "mid-day nap," comes from the Latin phrase sexta hora, "sixth hour," or noon. The prevalence of siestas in certain countries is probably connected to hot weather and traditions of large mid-day meals.
