Your Genes Could Affect How Well Your Body Adjusts to Daylight Saving Changes - ScienceAlert

In a study of around 830 people, researchers found early birds who usually went to bed earlier weren't as badly affected by DST as night owls who tended to stay up late.

From a sample of 831 interns at medical school, the researchers used genetic DNA profiling and a measure called the Objective Sleep Midpoint polygenic score to sift out the main study candidates: the 133 individuals most genetically predisposed to be early birds, and the 134 individuals most genetically predisposed to be night owls.

Here there were no significant differences in how early birds and night owls adjusted, suggesting our bodies find it easier to cope with that particular change.

"These genetic differences may affect how individuals adjust to jet lag or shift work as well," conclude the researchers in their published paper
