A new study revealed that sleeping in a room vulnerable to artificial light at night may lead to an increased risk of diabetes, according to the American “CNN” website.
According to the study, which was conducted on nearly 100,000 Chinese adults and published in Diabetolaogia, people who live in areas in China with high light pollution at night were more likely to develop diabetes by 28% of people living in the less polluted areas.
The researchers said that more than 9 million diabetes cases in Chinese adults aged 18 years or older may be due to open -air pollution at night, adding that the number is likely to increase with the transfer of more people to cities, however the lack of darkness It affects more than urban areas.
The researchers said that optical pollution in urban areas is so widespread that it could affect suburbs and forest parks that may be tens of or even hundreds of miles from the light source.
“The study confirms the previous research of the potential harmful effects of light at night on metabolic function and the risk of diabetes,” said Dr. Felis Zi, Director of the Center for Sleep and Medicine at Northwestern University, which did not participate in the study.
The health effect of light at night
Previous research has shown a link between artificial light at night, weight gain and obesity, disorders in metabolic function, insulin secretion and the development of diabetes, and cardiovascular risk factors.
A study published earlier this year examined the role of light in sleeping for healthy adults in the twenties and revealed that sleeping only one night with a dim light, such as the TV with a loudest, led to raising blood sugar and heart rate in youth during an experiment Sleep Laboratory.
Previous studies have shown that high heart rate at night is a risk factor for future heart disease and early death, while high blood sugar levels are a sign of insulin resistance, which can eventually lead to type 2 diabetes.
“It is very important to sleep in preventing the development of diabetes,” said Dr. Gareth Nai, chief member of the University of Chester University in the United Kingdom.
He added: “Studies have indicated that unwanted sleep patterns have been associated with an increase in the risk of the second type of diabetes. “.
