  • 80–90% of people can adjust their routine if work/school requires it
  • 5–10% are extreme morning people
  • 5–10% are extreme evening people

This article is about the after-lunch tiredness. Before going there however, we have to talk about the sleeping cycle. According to this 2005 study from the University of Pittsburgh, what really influences your post-lunch fatigue are more elements like:

  • sleeping patterns,
  • melatonin level
  • carbohydrate amounts.

For a long time, many assumed that eating a heavy lunch was the only cause of sleepiness. However, it has much more to do with your circadian rhythm rather than the food you ate. What do I mean by that?

In the hottest days in the savanna, where the Homo sapiens developed, an afternoon nap was a good way of getting through the day. Predators were resting in the shadows and the early humans took advantage of this to recharge their energy by sleeping and eating.
