Two or three days after the festival, the work efficiency is very low, and I can't enter the state for a long time. Feeling irritable, inattentive, depressed, listless, even physically and mentally weak, headache, fatigue, loss of appetite, insomnia, drowsiness and other discomforts, and some even accompanied by negative emotional reactions such as depression, loss and anxiety. This is the so-called "post-holiday syndrome". This is because the Spring Festival is too busy, the body does not have enough rest time, and the biological clock is disrupted, leading to autonomic nerve dysfunction. Entering normal life, the biological clock can't be adjusted, and the relaxed "string" can't adapt to the busy work for a while, thus producing various symptoms.
