Scientists from the British Shari Sleep Research Center revealed that shift work disrupts the deepest molecular hierarchy of the human body.
Experts say that the scale, speed and severity of physical damage caused by staying awake at night is surprising.
The human body follows a natural rhythm, the so-called biological clock, which goes to sleep at night and stays awake during the day.
The biological clock has a profound impact on the human body, which is related to regulating hormones, body temperature, exercise capacity, emotions and brain operation.
This study tracked 22 subjects to observe their physical condition as they transitioned from a normal lifestyle to night shift workers.
Blood tests show that the human body usually has 6% of genes, which are precisely set to be more active or less active at specific times of the day.
Once the subjects switch to night work, that kind of gene precision regulation will be lost.
The researcher said: "This is time chaos. It's like living in a house where every room has a clock. Now, the time in every room is chaotic. Of course, the whole house will fall into chaos."
Studies have shown that shift workers sleep too little at the wrong time, which may increase the risk of type XNUMX diabetes and obesity.
This research was published in the American academic journal "Proceedings of the National Academy of Sciences."
