Research results that shift work such as night work is related to brain volume reduction

work (commutation work), including night work and early morning work, is a work style that can lead to sleep disturbances and fatigue. In order to find out how shift work affects the brain, Dr. Thomas Welton, a neuroscientist at Duke Singapore’s National University, analyzed over 14,000 脳 data.

There are many people who work in different time zones such as nurses, doctors and employees who work throughout the night. work has been reported to be related to sleep disturbance, co function, metabolic disease, and neurodegenerative disease risk, but the relationship with brain structure was not sufficient.

Wellton’s research team used UK Biobank data, a large-scale living database in the UK, to analyze 144 adult workers with no serious health problems. The median age was 47 years old. The research team compared 153 items related to brain structures such as brain volume and neurofibre state using self-declaration data related to health, sleep, co。tion and 。 of participants.

As a result of analysis, shift workers tend to have a small volume of right and left tonsills. The eyelid is a part that relays information in the brain. It is also related to sleep and stimulation adjustment and memory recall. The tonsil is a site that adjusts the reaction of恐怖s such as fear and anxiety.

The research team believes that some of the brain is becoming more susceptible due to disturbances in the body watch for the selective volume reduction of gaze and tonsils seen by a healthy shift worker. These areas relate to fatigue and mood disturbances related to shift work. In the following image, the area where volume declines have been shown in yellow, and the depth of yellow indicates that the volume tends to be small by shift workers.

However, Science Alert, a science-based media, noted that the part of the brain is not always dead because it has been affected by volume. The brain explains that it is a flexible organ that replaces the nervous circuit according to the situation, and some compensation may occur in the brain of the shift worker to work overnight. Similarly, the research team said, “A person who does not have a change in the brain can not withstand shift work, and as a result, it can be biased by a non-shift work.”

In addition, the research team reported that the decrease in volume of the brain related to shift work has occurred within 2.4 years as a result of tracking and、yzing the shift work. Mr. Wellton said, “The changes in the brain structure related to shift work are not fixed, and they indicate that it is subject to prevention and recovery,” he explains that measures such as monitoring, counseling, and working schedule adjustments can be considered to reduce the volume of shift workers.
