A new Belgian study shows that people rely on two different internal “time keeping devices” to regulate their sleep patterns.

Scientists have long noticed how sunflowers turn toward the east as the sun rises, continuing to follow the sun as it journeys across the sky throughout the day. However, exactly why sunflower behave in this way hasn’t been known, until now.

The body seems to run like a well-oiled machine when people listen to their internal clocks. For example, the body “prefers” sleeping at night instead of during the day, and working during the day instead of at night.
The same is true when it comes to eating patterns, say researchers. When a person eats may be just as important as when they sleep.
