Doctor at Oxford University:

Pressing staff to work before 10 am is equivalent to torturing employees, making them sick, tired and stressed. It is claimed from research by experts at Oxford University.

Before age 55, the biological rate that appears once a day in humans will be completely disordered when working 5 to 9 hours. With that amount of work, work will become "a threat" to psychological health.

According to Dr. Paul Kelley at Oxford University, we need a major change in the timetable and current work , to better fit the human biological clock.

We need a big change in the timetable for learning and doing today.

Experimental studies of circadian rhythms show that an average 10-year-old child will not be able to concentrate fully before 8:30 am. In the same study, scientists pointed out that 16-year-olds should start studying at 10am, and 11am is the best starting time frame for college students.

Dr. Kelley believes that adjusting the school timetable as such will increase the student's average score by up to 10%. Previously, Dr. Kelley was a teacher at Monkseaton High School, north of Tyneside. At that time, he switched teaching hours from 8:30 am to 10 am, and found that the number of students' high scores increased by 19%.

Similarly, companies that force employees to go to work earlier than normal will cause them to reduce productivity as well as affect their health.

We are in the hands of a society that lacks sleep, which is very dangerous.

"This is an extremely big social problem , " Dr. Kelley said. "Staff should start working from 10 am, and when you are 55 years old, you should go back to the working hours starting at 9 am. We are in the hands of a sleepy society, it's very dangerous dangerous ".

"That lack of sleep affects and harms the body's functioning system, from the physical to the psychology and productivity of an individual."

According to Dr. Paul Kelley, liver and heart will have a natural tendency to work when making them work wrong hours. He said that this is a global problem, everyone is suffering from it now.

"We can't change the 24-hour biological rhythm of the human body. Your body will interact with the sun and that's what makes you wake up, not when you see the sun. wake up".

The lack of sleep is a physical and mental torture.

He also added that getting up too early can affect patients and prisoners, when they get up wrong, give them what they don't want. In summary, he said the lack of sleep is a physical and mental torture.

Research shows that lack of sleep affects work productivity, mental state, concentration, long-term memory and tends to make people seek drugs and drugs. Besides, other consequences such as irritability, inhibition, hypertension, weight gain, weakening of the immune system, etc.

Neuroscientists say that the biological mechanism of teenagers makes them go to bed at midnight, which will make them unable to fully awake until 10 am. According to Dr. Kelley, teenagers lack an average of 10 hours a week, when they have to get up early to prepare for school.

Late start of class will have a very positive effect.

"Just changing the time to start the morning study, we can enhance the quality of life of an entire generation," he added and emphasized. "We have the opportunity to create benefits for millions of people on this Earth."

The actual test showed that the group of students who started studying at 10 am had a better test score, indicating that the late start of class would have a very positive effect.

Currently, students from 100 UK schools will take part in a multi-year test, based on scientific evidence, indicating that teenagers are suffering from biorhythms when they have to go to school early. . The research team expects to announce the results of the study in 2018.
