Are you an early riser or do you prefer waking up when the sun is overhead? Your hair may be an indicator — says a new study.
According to National Geographic News, that’s because the genes that regulate our body clocks can be found in hair-follicle cells, researchers have discovered.
Makoto Akashi, of the Research Institute for Time Studies at Yamaguchi University in Japan, and colleagues conducted the study on hair samples of four subjects who followed a strict schedule as per their preferences — waking up early or late and eating, among other lifestyle choices.
When the researchers tested the genes in the subjects’ follicles, they found that body-clock gene activity peaked right after a subject had woken up, be it 6 am or 10 am.
This indicates that the brain “turns on” the genes at different times of the morning in different people. —ANI
