Sleep
During daytime, the sun is out, and most people are awake. They work, go to school, or complete daily errands and activities. Many people sleep for a short time in the early afternoon for a quick rest—or because they are not able to sleep during the day. This is called a nap. A successful nap should run between 15 and 30 minutes, and longer naps taking 30–60 minutes will result in feeling dazed and less attentive.
