Yuma’s location at the confluence of the Colorado and Gila rivers makes for lush, fertile soil — every season is growing season here.

How Does Sunshine Duration Affect Sleep?

Exposure to sunshine is a key part of sleep hygiene. Light rays influence the brain’s biological timekeeper, which has been true since humans slept outside and would rise with the sun. In fact, light is one of the biggest external factors that influence sleep. The National Sleep Foundation recommends cocooning your bedroom in blackout curtains or blinds during the night to block artificial light and opening them to the sunshine when you are ready to begin the day.

In some areas of the world, such as Dikson, Russia, people can experience an entire month with no sunshine whatsoever. The absence of a typical day and night cycle can have significant affects on the sleep and wake cycle and studies have shown it can lead to symptoms such as insomnia, decreased total sleep time, decreased sleep quality and efficiency, and instability of the REM sleep stage.

  1. I have troubles understanding how no Spanish city (e.g. Malaga) would have more sunshine than Marseille in France. What’s the source for your data?
