1, sleeping under the light affects cardiac rehabilitation.
In a study funded by the National Institutes of Health, neuroscientists at the University of Texas at Austin and the University of West Virginia School of Medicine found that night lighting is usually used in wards, which is associated with high inflammation, brain cell death and heart disease patients.
The research team first reproduced cardiac arrest with animal models, and let three groups of subjects spend the night in weak red light, weak white light and darkness. After seven nights, the researchers assessed their health.
The results show that exposure to white light at night will lead to a series of adverse consequences: the mortality rate of the group exposed to white light increases, but there is no difference between the group exposed to red light and the group exposed to darkness. Researchers believe that exposure to white light at night will affect the hippocampus, leading to a stronger inflammatory response. Hippocampus is a part of the brain and plays a key role in the formation of memory.
2, turning on the light to sleep can easily lead to obesity.
Researchers say that night lighting can make mice gain weight quickly. In the eight-week experiment, mice exposed to light at night gained 50% more weight than mice exposed to dark environment. All mice eat the same amount of food. The difference is that mice exposed to light at night eat 55% more food at rest.
Professor falcone said that this research has not been tested on human beings, but the results are of great significance to human beings. She said: "If you eat at the wrong time of day, or when your body is resting, your metabolism will be disordered, which will lead to weight gain."
Turning on the light will disturb the biological clock.
Professor Ken explained that the night light disturbed the circadian rhythm of the human body, and black and white were reversed. In the research of many scholars, according to the biological rhythm of people's psychology, physiology and psychological activities, arranging the work and rest system for one day, one week, one month and one year can improve work efficiency and research results, relieve fatigue and prevent diseases and accidents.
On the contrary, if you don't arrange rest according to the circadian rhythm of the internal biological clock, you will feel physically tired and mentally unwell.
4, turning on the light to sleep will lead to insomnia.
According to a study published in the British journal Physiology Report, exposure to bright light during sleep may cause the body to stop producing melatonin, thus affecting the quality of sleep and leading to insomnia.
5, turning on the light to sleep will induce depression.
Ming, deputy director of Shanghai Chinese Medicine Insomnia Cooperation Center, said in an interview with The New York Times that if the light is too strong, sleeping in the bedroom will make the body's biological clock and endocrine disorders, and the biological clock and some endocrine disorders will lead to sleep problems. On the contrary, people's mood is changeable, and the longer the time, the higher the risk of depression.
