Are you more of a morning person or do you tend to be more productive at night? According to a new study, whether or not you’re an early bird or a night owl is actually in your DNA.

Researchers found 15 different spots in the genetic script that was likely between morning people and self-described evening people. Seven of these genetic swaps occur near genes involving regulating a person’s daily cycles or circadian rhythm.

Here’s my take:

• Try to really pay attention to your body and figure out if you’re a morning person or an evening person.

• Don’t fight mother nature. Although I’ve had to work many all-nighters as an OB/GYN, most of my life as a doctor and a mom involves waking up way before 6 am. But try to make me stay up late? That’s a different story.
